How to Maintain Motor Graders for Fine-Grade Accuracy?
Even trained and experienced operator may not be able to achieve the required accuracy if the motor grader is not in good shape and properly maintained.
One of the major problem in achieving the specific grade result is improper adjustment of the turn circle and blade lift contact points. Thus, as per the experts, operator experience, circle adjustments and visibility are few factors that can surely help in achieving fine-grade accuracy.
Here is a list of all those points and maintenance tips that you need to keep in mind so as to achieve fine-grade accuracy…
1. Pay heed to the circle and moldboard system:
Industry experts believe that most important maintenance items of the motor grader are in the circle and moldboard system, circle wear inserts, cylinder ball joint shims, moldboard cutting edges, circle and pinion teeth, moldboard pivot joint and saddle assembly. As more and more play is introduced in the system as these components wear, it can prove to be harmful in the longer run. In fact, if there is play in the system, then even if the operator tries to reach a specific grade, the elevation of the cutting edge may change. In such cases, even the electronics of the machine or operator can’t detect the change and the result can be the final grade which is not up to the mark.
Typically, after every shift every day, the turning circle, lift cylinders and moldboard slide should be checked for any play. Here, the role of operator comes into picture as it is he who needs to check whether these areas have started to wear and require adjustment and/or replacement. In fact, operator can better know when the time for maintenance is.
Further, it should be noted that if the joints become too sloppy and loose, then they can negatively affect the finished surface. In order to check for the excess wear, the drawbar, circle and moldboard should be lifted off the ground. If the lift cylinder rods move without immediate cutting edge movement, this linkage is considered loose and needs to be adjusted properly.
Another point towards which attention should be paid is when the moldboard slide rail is out of adjustment, then the moldboard may start to chatter which is when the moldboard wiggles back and forth, fore and aft. A washboard effect can be created on the finished surface due to this. Hence, an inspection should be performed and for that the end cap for the slide rail inserts should be removed. Then the moldboard should be lifted in the air and gaps between the insert and the rail should be checked. For checking the drawbar wear inserts, the moldboard should be raised off the ground and then inspected for a gap between the wear insert and the drawbar plate.
The other thing that should be checked regularly is cylinder ball joint wear which can be very easily seen from the operator’s seat. You should also make it a point to eye the upper saddle assembly and trunnion. They should be serviced as needed.
Last but not the least, speed and power of your circle turn can play a very important role when positioning a blade for final grade. A good operator should constantly adjust the circle turn and blade lift as per the need. Experts suggest that the clearance of the blade lift cylinder ball and socket arrangement should be checked every 250 hours.
2. Focus on the cutting edge
It is the cutting edge which helps the motor grader in maintaining the accuracy of a cut. Hence, it is extremely necessary to replace it if it is worn out unevenly. Cutting edge wear can occur in the middle as well as the corners creating an uneven surface. The edge should be replaced before wear occurs on the bottom of the moldboard and reduces cutting edge support.
For cutting edge replacement, there are no fixed rules. If the cutting edge sees even wear across the entire length of the edge or the edge is properly maintained, then accuracy may not be sacrificed. At the same time, the productivity will also be constant until the edge is worn down to the point that the cutting edge hardware is contacting the surface.
Generally, it is seen that the life of the edge depends on the operating conditions, blade down pressure and how abrasive the material is.
3. Pay attention to the tires and drivetrain
The tires and transmission which constitute the drivetrain play an important role in achieving accuracy of the final grade. Inconsistent tire pressure can have a negative impact on the ability of the equipment to reach the final grade. Here, it is to be noted that all the tires should have the equal pressure. This is because it changes the blade height, requiring a recalibration of the grade control system. Unequal tire pressure can also affect traction and the machine response.
Attention should also be paid to the tread pattern. Some tire tread patterns are better suited for finish grading than others. The final grade is also affected by the lug pattern.
When the discussion is about the tires, then it should also be noted that even mismatched tires can create a huge problem. Hence, it is necessary to use the same size tires of the same type and same age (tread).
When it comes to the drivetrain, then the most important thing is to have a selection of ratios in the working range of the machine.
4.Make use of the available technology
These days, the modern grade control systems allow you to make fine adjustments and tailor a motor grader for optimum performance. However, merely understanding the grade control system is not enough. Understanding of the equipment is also of vital importance. In addition, proper maintenance of both the motor grader and grade control system is necessary too. Lack of knowledge on the part of the operator can mean that all the technological features are not put to use which may affect the final result.
In a nutshell
Mastering the moldboard, circle, drive train and technologies can greatly impact the motor grader’s performance and help in achieving the fine-grade accuracy.
Maintaining Tight Motor Grader Circles to Get Accurate Grades Fast
Thus, in order to get the accurate grades fast, an experienced operator needs to take into account various factors.
In order to understand in detail about how to get accurate grades fast, the below mentioned tips should be followed…
1. The importance of maintaining tolerance
a) It is better to keep the components tighter for faster grade accuracy. Tightness in the moldboard slides, circle supports, drawbar ball stud and even the operator’s seat are all important factors to consider when determining if the grader can produce a finish grade to the tolerance specified. For that, the critical areas of the circle and moldboard slide should be inspected frequently, if not daily.
b) There are chances of wear and loss of blading tolerance wherever there is a sliding surface. Hence, the circle support shoes, moldboard slides and connection between the lift and sideshift cylinders and the drawbar should always be considered by the experienced operator.
c) It is generally seen that when the clamp and guide shoes in the circle turn system are worn or out of adjustment, it can restrict the circle’s rotation, thereby not allowing quick and accurate adjustments while grading. Hence, care must be taken.
d) Close attention should also be paid to the trunnions which hold the blade shift cylinder and receive the majority of the shock loads during grading. If the grader develops excessive wear in the trunnions, then the ability to hold tighter tolerances is lost.
e) Further, even out-of-tolerance components can create excessive wear. If the circle and slide is not maintained within 1/16 to 3/16 in., the result is premature wear. Hence, close attention should be paid towards this.
2. Cutting edge monitoring
The cutting edge of the motor grader is highly affected by the type of material the equipment is working with. For example, very rough material can cause wear to the cutting edge in a very short span of time like an eight-hour shift and soft material can help the cutting edge to last for a month. Hence, the cutting edge should be checked frequently. Since critical tasks are performed by the cutting edge, a worn blade can make it nearly impossible to achieve a close tolerance grade. This can result in more time needed to complete the task which in turn can affect the operating cost. Hence, the cutting edge should be maintained properly and changed if needed as the cost of re-grading the surface to compensate for the worn edge may be much more.
There are a couple of indicators that can alert the operator about when the cutting edge should be replaced. Two main indicators include when the cutting edge wears to be even with the moldboard and when the uneven wear across the width of the cutting edge can be visually seen. Typically, all the edges should be changed across the length of the moldboard at one time, otherwise, it might not give the required finish grade. Also, the mating faces of the edge and moldboard should be free of any dirt and grit. Here, it is to be noted that the quality of blade when replacing the cutting edge can also make a difference and here the operator experience comes into picture who knows what is best for the equipment keeping in mind the operating conditions.
3. The need for maintaining the components
If the motor grader is not maintained properly, the ability to get accurate grades fast will definitely suffer. So, here are some maintenance tips:
a) The turntable and moldboard slide tolerances should be maintained as close as possible as if the wear reaches or exceeds the tolerances, then it might not be possible to achieve accurate grades fast. Hence, regular maintenance of critical moving parts is the key to help prevent excessive wear. This requires vigilant record keeping of the service intervals. The service intervals for all parts as recommended by the manufacturer should be followed.
b) There are various wear areas in the motor grader that require constant attention. The most common wear points include the cutting edge, blade slide guides, circle guide shoes on the turntable and blade lift cylinder connections. As these components wear, more play is introduced into the system. Hence, they need to be regularly checked for excessive play which is the enemy of accuracy and productivity and make the system loose. It is better to inspect the equipment every day before use.
c) All the wear items ranging from the ball stud to the drawbar, along with the clamp and guide shoes and cutting edges that are critical for the motor grader’s daily performance should always be stocked.
d) All the moving parts of the equipment should be properly greased.
Thus, by following the above mentioned tips, accurate grades can be reached much faster.
In a nutshell
Overall, the tighter the system, the faster the grade can be achieved. Hence, all what is needed is maintaining tolerance, cutting edge and various other important components of the motor grader that have a maximum impact on the grading performance.
Tips for Keeping the Motor Grader Blade Sharp
If the blade is worn out, then it can cause major problems in the future. For example, if you want to penetrate and cut material but your blade is dull or badly worn out, then it can give an excessive shock. Also, it can put pressure on the rest of the motor grader including the frame and drivetrain. This can further damage or significantly shorten the life of components that may be very expensive and difficult to replace.
Worn out blade can also make the motor grader less efficient and impact the overall productivity. This is because the motor grader would require more horsepower to force the blade through each cut which can lead to higher fuel costs and more wear and tear on tyres. Looking at the above scenarios, it goes without saying that keeping the motor grader blade sharp at all times is of utmost importance and the responsibility of doing so is on the shoulders of the motor grader operator. An efficient motor grader operator should have knowledge about how to protect the blade when needed to keep its edges sharp.
Here is a close look at the tips shared by various industry experts on keeping the motor grader blade sharp…
1. The role of motor grader operator in keeping the blade sharp:
Everything boils down to the fact that it is the motor grader operator who through his skills, experience and know-how can make the proper use of the blade. An expert operator is expected to keep the blade sharp and even by significantly reducing wear and tear on the graders cutting edge. For that, it is extremely important for the operator to position the moldboard correctly and use appropriate speed, thereby, avoiding jerky movements.
2. The importance of positioning the blade right
Sometimes, in an attempt to see the cutting edge, operators might keep the moldboard pitched forward. However, this can prove disastrous as this can prematurely blunt the edge, thereby, making the task of cutting and trimming much more difficult. So, it is best to avoid such a positioning of the blade. As a matter of fact, the top of the blade should be just moved slightly forward of the cutting edge, so as to pitch the blade forward only when it is necessary to make a cut.
Apart from this, it is equally important for the motor grader operators to change the blade angle periodically. If the moldboard is kept forward, it might result in wear just along the front of the cutting edge. Hence, periodically tilting it back like in case of carrying, mixing, spreading or combing material can even out the wear across the edge, thus, keeping the blade even and sharp.
In order to prevent the cutting edge from becoming rounded along just one side, the motor grader should be used to scarify or rip a surface. This can also help in keeping the blade sharp.
At the time of grading curbs, it is very important to switch between leading with the left and right side of the blade. In fact, the entire length of the moldboard should be used, preventing uneven wear only to the outer sides of the leading edge.
3. The importance of speed
Typically, in the grading processes, the motor graders should be operated slowly and smoothly, so as to avoid unnecessary wear and tear of the blade. In fact, it is best to keep the speed below 10 kilometres per hour and should never be exceeded above 16 kilometres per hour.
Apart from keeping the speed slow, avoidance of jerky motions can also help in minimising the stress on the blade. This can prevent shock loads that can damage other parts of the motor grader.
Replacing the blade when necessary
Given the above tips for keeping the motor grader blade sharp, it cannot be denied that the cutting edge will wear off in some time due to continuous usage and will have to be replaced eventually. This makes it important to inspect the blade regularly.
Generally, a motor grader gives optimal performance with about 3.5 centimetres of useable space exposed on the cutting edge. If this edge gets worn down further, the grader will not work efficiently.
As per the manufacturers, depending on the type of material that is being cut by the motor grader, it is recommended to visually inspect the cutting edge after every 25 to 50 hours.
To sum up, the blade of the motor grader is an important component and should be used and inspected wisely. Here, it is to be noted that if you opt for Mahindra RoadMaster G75 or G90, then you might not worry much about the cutting edge of the blade as it has lasting life of about 600 hrs on standard operation cycle.
A note on Mahindra RoadMaster G75’s and G90’s blade and its cutting edge
The 3000 mm moldboard of RoadMaster G75 and G90 come with an option of having its size reduced by 400 mm. Depending on the requirement, the blade size can be reduced by 200 mm on both sides. The cutting edge of the blade of the two equipment is in four separate pieces for ease of handling and replacement. It is convenient, affordable and any blade part can be easily replaced in case of damage. The two equipment also offer full blade visibility from operator station for superior grade finish.
In a nutshell
Since blade is the most expensive or time-consuming part to replace, it is better to keep the blade in good order and sharp so as to avoid many problems later on. Above mentioned are few tips that the motor grader operators can follow to achieve maximum efficiency and productivity with their motor graders at the jobsite. Further, it is better if the motor grader operators or contractors opt for an equipment whose blade’s cutting edge can last long. Here, RoadMaster G75 and G90 deserve a special mention. Isn’t it?

12. Ensure that the bucket teeth are all there with retainer pins.
13. You need to check all the attachments of the BHL before and after work.
14. You also need to make it a point to check the fuel levels and document the periodic refills. Also, the hydraulic fluid level before and after using the equipment should be checked.
15. Use fuel which is prescribed by the manufacturer and avoid adulterated fuel which can reduce the life and productivity of the equipment.
16. Without fail, look out for any clear signs of oil leakage. There are many protocols and ways to carry out this inspection. If you are smart enough to pay attention to the leaky valves, you can carry out repairs much faster, thereby, preventing the machine from further damage.
17. Properly grease and lubricate all moving parts of the equipment in order to save them from failing to work and creating excess friction leading to severe wear and tear of the machinery, frequent breakdowns and shorter life span. If you hear noise coming from any part of the equipment like around pins, bushings, pivot points and bearing joints, you need to grease those parts properly. For greasing, refer to your operation and maintenance manual to learn about the specifications of the manufacturer.
18. All the electric wires in the Backhoe Loader should be protected from exposure to harmful external elements. This can be done by covering critical wires properly or sheltering the whole equipment under a covering.
19. BHLs are often employed in rough terrains and this may lead to misalignment of the equipment in certain situations. Although, BHLs are made in such a way that they can withstand adverse conditions, however, assuring proper alignment of the equipment remains a crucial task.
20. It is necessary to confirm that all safety features of machine are working aptly.
21. The equipment should be stored in cool and dry place, protected from all the contamination.
22. Always avoid engine idling as much as possible.
23. Create and follow a maintenance schedule. Include notations on how often each part of the machinery should be inspected for problems, repairs and general maintenance.
24. BHL operators should be trained well regarding Backhoe Loader operation and preventive maintenance measures. Without proper operator training, operators can damage the machinery or even injure themselves or others.
Overall, by following these simple preventive maintenance safety tips, BHL’s lifespan can be increased considerably. These small but important tips can help to increase productivity as well as efficiency of the equipment to a very large extent.
In a nutshell
From construction work to building roads, utility work to landscaping, backhoes are used almost at every jobsite and in every industry due to their versatility. Since, BHLs are put to use for numerous applications, they work for long hours and in difficult terrains. This increases the need for BHL maintenance. In fact, if not properly cared for and maintained, BHLs can go from productive and valuable to idle and costly. Hence, following the preventive maintenance in case of BHL is very important.
Motor Grader Inspection Checklist
Here is an extensive check list of things to inspect before and after a motor grader is used for the task for the day.
From the ground
1. Check the condition and cleanliness of steps and handholds since they are used to take support when getting on board the machine. Broken steps may lead to injuries opening up the company to compensation claims.
2. Its necessary to check the inflation of tires to ensure they can take the weight of the machine and the stress that the machine has to put up with. If the tyres re not inflated enough, it burdens the motor and may lead to higher fuel consumption as well.
3. Damage to lug nuts needs to be inspected thoroughly to avoid possibilities of any major damage to the machines and or break downs.
4. Stem covers of brakes need to be check to ensure that the brakes are covered and protected.
5. Tandem housings need to be checked for dirt, trash build up and leaks. They should be kept clean at all times.
6. Articulation area needs to be checked for trash or dirt build up since the build up can lead to problems with movement of the machine parts and eventually break downs and system failures.
7. Air reservoir should always be checked for drain water and sediment. Build up in the air reservoir leads to reduced efficiency of cuimbsion in the engine thus increasing fuel usage.
8. Transmission leaks should be for regularly. Transmission leaks can lead to malfunctioning or underperformance due to the leaks. Any leaks that are found should be repaired immediately on priority.
9. Differential and tandem leaks under the machine need to be checked when doing an inspection. Leaks in differentials can again lead to power loss issues and break downs in the long run if they go unchecked.
10. Hydraulics powers all the hard work that the machines does. Fluid levels, drainage and leaks of hydraulic oils should be kept in check. Low oil levels can affect the performance of the machine while drainage and leaks can cause power loss and malfunction if gone unchecked
11. Check if the covers are damaged and if guards are secure
12. Batteries and hold downs need to be checked for loose nuts, bolts and cleanliness. Loose nuts and bolts in the battery and dirt at connection points can cause the battery to under perform and get discharged faster.
13. Fuel tanks tend to get dirty very fast and need to be kept clean to ensure no debris make it into the engine. Fuel levels if below 30% should be topped off. Any damage to the fuel tank must be reported and repaired immediately. Leaks, drain water and sediment in the tank are signs of bad maintenance.
14. Hydraulic cylinders, tubes, hoses and fittings should be checked for any damage, leaks wear and tear from working in harsh conditions at construction sites. Damage to hydraulic cylinders brings down the performance and can result in major expenses due to system break down.
15. Circle drive leaks should be checked and repaired if any are found.
16. Front wheel spindle bearings should be checked for leaks and should be reported and repaired immediately if any are found
17. All wheel drive motors should be checked extensively for damage and leaks. Damage to the wheel drive motor can bring the grader to a stand still if left unchecked.
18. Blade linkage should be checked for damage and loose or missing bolts. Damage to the linkage can eventually lead to damage to the whole linkage system and by extension the blade too.
19. Blade and end bits need to be checked for excessive wear or damage. The blade is at the forefront of the war being done on site at receives the most stress during execution so should be kept in the best of states at all times and cleaned regularly to ensure rust doesn’t set in.
20. Over all the machine should be checked for loose or missing nuts & bolts in addition to loose guards, the over all wear and tear of the machine and its cleanliness.
Engine compartment:
1. Engine oil Fluid levels should be checked and topped up if required, with appropriate quality and quantity of the recommended oil.
2. Engine coolant fluid levels should be checked properly and topped off as required. Low levels of coolant may lead the engine to heat up too much and cause damage.
3. Engine pre cleaner dirt build up should be checked.
4. Air filter restriction indicator should be monitored. Choked air filter can lead to poorer performance of the machine and also increased fuel intake.
5. Radiator Fin should be checked for blockage and leaks. Radiators are essential in helping keep the engine cool enough to ensure optimal performance.
6. All hoses should regularly be checked for cracks, wear spots, leaks. Weak spots can give in and cause major damage unless monitored regularly with inspections and maintenance. Hoses again have to manage a lot of harsh conditions and need additional scrutiny to ensure the machine keeps running at optimal efficiency.
7. All belts should be checked for tightness, wear and cracks. Loose belts cause increased loss of power during the transfer. Belts may break and cause damage if the wear and tear isnt kept in check.
8. Over all engine compartment should be kept clean and tidy. Dirt and grease build up in the compartment affects the performance of the engine negatively.
Outside the cab
1. Light lenses should be checked for cleanness and damages. Dirty lenses reduce the lighting necessary for the operator to have the adequate visibility required when working at night or early evenings
2. Mirrors and windows should be checked for damage and cleanliness. Dirty windows and mirrors affect operator visibility and can led to accidents.
3. Windshield wipers and washers Wear, damage, fluid level should be checked and topped up as and when required
Inside the cab
1. SeatAdjustment and pedal travel should be checked. Pedal travel should be checked to ensure that the pedals are functioning properly and arent jammed.
2. Seat belt &mounting should be checked for damage, wear and adjustment. They are mandatory for the safety of the operator when operating the machine.
3. Fire Extinguishers have to be present in the cabin and be charged. Any damage to fire extinguishers should be reported. Fires getting out of hand can cause a lot of damage.
4. Horn, backup alarm and lights should be checked to ensure they are functioning properly. Failure of any of these things can lead to accidents on rather noisy sites.
5. Controls and gauge lenses should be checked for damage, cleanliness andits operational states. Malfunctioning gauges and controls can led to under or over utilisation of the machines and eventually cause damage.
6. Overall Cab InteriorCleanliness should be maintained.
Regular maintenance and inspection is necessary to keep the machine in the a robust condition to get all the necessary work done without burning a huge hole in the owners pockets and at the same time mining larger profits from using the machine.
Major Characteristics of an Excellent Mini Grader Mechanic

While India doesn’t have a very strong infrastructure for certifications when it comes to mechanics, any kind of government recognised certification is always a plus to add credibility to the mechanic’s skills. While certification is not a requirement for mini grader mechanics, it demonstrates a sense of motivation and ambition to both employers and customers. Certification also ensures that the mechanic is up-to-date on the latest technologies and techniques in the industry. Constantly upgrading certifications can help them be better at diagnosing and solving problems that are constantly evolving with newer technologies.
Personal Tool Inventory
Construction equipment like mini graders have at times common and at times special tool requirements. Though not always required of a mechanic, a personal inventory of high-quality tools can ensure that a mechanic feels comfortable using tools, and learning new tools as they become available.. Many mechanics use their own tools on customers’ mini graders. However in case a certain type of custom tools are required for a certain brand of graders, then the mechanic should be well informed and comfortable using the same to ensure best service to the customers.
Strong Customer Service Skills
Depending on the ownership of the machine, the mechanic may be required to deal with all kinds of people who may or may not know enough about the mini graders. Given that generally it is the operators and managers that look after the machines, it is necessary for the mechanic to have good communication skills to both listen and understand the problem and be able to explain in simple terms as to what the issue with the machines is how to best solve it. Mechanics needs to have great interpersonal skills to be able to put all kinds of customers at ease not only about their diagnosis but repair suggestions too.
Strong Communication Skills
Good communication skills are a must for a mechanic, so as to ensure that the customer understand clearly the issue with the machine in simple terms. A mechanic should have adequate understanding of how to translate technical and complex jargons in simple layman terms in order to enable the customers to understand it better. Good communication skills are required to enable the process of diagnosis and repair to move faster through approvals with the concerned people.
Solid Work Ethic
Work ethics are necessary given the fact that these are pricey machines that have a lot of time and money invested in them. A great mini grader mechanic has a solid work ethic. He is committed to quickly solving and repairing problems and is honest with customers.
Perseverance
Even with the most finely-honed problem-solving skills, mechanics are bound to encounter issues they can’t solve the first time around. they need to have the ability to stick to it until a solution is found. Having the necessary perseverance to see that the issue is solved is a solid characteristic of a great mini grader mechanic. Great mechanics are willing to collaborate with others to ensure that their customers get the best possible service and the solutions are in their best interests.
Attention to detail
Great mechanics need to have an eye for attention to detail given the complex structure of the mini graders. Whether working on maintenance, diagnostics, or repairs, mechanics have to perform thosetasks with exacting detail. That is because careful work on important vehicle components could save someone’s life!
Motor Grader Tips: Changing and Keeping the Blade Sharp
They have a long wheel base that can span short depression or humps. Typically, motor graders possess a centrally located blade that can be angled to cast out on either side. The part of the grader which is used to cut, mix, windrow and spread material is called the mouldboard. Mouldboard with the cutting blade is attached to the circular part of the motor grader located under the frame i.e., the circle. The mouldboard allows the blade to be adjusted for height, angle, pitch and reverse direction. Blade angle refers to the angle of the blade in relationship with the mainframe which generally represents a 180 degree or straight line.
By the above description, you might have understood that motor graders are a little tricky to handle and generally, out of all the heavy equipment, they are perceived to be the most difficult vehicles to drive as they differ in terms of setting the controls such as the angle and height of the blade which requires certain skills, especially when setting them to obtain fine degree of result. Hence, motor graders demand experienced and trained operators who can move the maximum amount of material in the minimum possible time, safely run the machine and are aware about how to cut down on the unnecessary wear and tear. Above all, one of the most important roles of the motor grader operator is to keep the cutting edge sharp. This involves knowing how to operate the grader to protect the blade and when necessary, to whet its edges.
Why the hoopla about motor grader blade?
You might wonder as to why so much worry about the blade. Well, you must know that the efficient working of the motor grader depends on its blade, its condition and position. Further, since blade is the most expensive or time-consuming part to replace, it is crucial for the motor grader operator to always think about the blade and operate it wisely.
In fact, if the blade is not in a good condition, then it might pose many problems. For example, if you want to penetrate and cut material but your blade is dull or badly worn out, then it can give an excessive shock, putting pressure on the rest of the motor grader (including the frame and drivetrain). This can even damage or significantly shorten the life of components that may be very expensive and difficult to replace.
Further, a worn out blade can also make the motor grader less efficient. How? Well, more horsepower would be needed to force the blade through each cut. This may result in higher fuel costs, more wear and tear on tyres, thereby, lowering overall productivity.
Tips for keeping the motor grader blade sharp
1. It goes without saying that an expert motor grader operator can significantly reduce wear and tear on the graders cutting edge and help to keep it even and sharp. Here, it is to be noted that in order to keep the blade of a motor grader sharp, its vital for the motor grader operators to position the moldboard correctly and use appropriate speed avoiding jerky movements.
2. When operating a grader, the operator may choose to keep the moldboard pitched forward so as to see the cutting edge. However, this can be a disastrous move and can prematurely blunt the edge. This can make the task of cutting and trimming very difficult. Instead of this, in order to keep the motor grader blade sharp, experienced operator need to keep the top of the blade just slightly forward of the cutting edge, so as to pitch the blade forward only when its necessary to make a cut.
3. It is also required of the motor grader operators to change the blade angles periodically. If the mouldboard is kept forward, it might result in wear just along the front of the cutting edge. Hence, periodically tilting it back like in case of carrying, mixing, spreading or combing material can even out the wear across the edge, thus, helping keep it even and sharp.
4. Employing the motor grader to scarify or rip a surface can also help keep the blade sharp. This can prevent the cutting edge from becoming rounded along just one side.
5. At the time of grading curbs, it is very important to switch between leading with the left and right side of the blade. In fact, the entire length of the moldboard should be used, preventing uneven wear only to the outer sides of the leading edge.
6. Typically, in the grading processes, the motor graders should be operated slowly and smoothly, so as to avoid unnecessary wear and tear of the blade. In fact, it is best to keep the speed below 10 kilometres per hour and should never be exceeded above 16 kilometres per hour.
7. Last but not the least, avoidance of jerky motions also help minimise the stress on the blade and prevent shock loads that can damage other parts of the motor grader.
Tips for changing the motor grader blade
It should be remembered that even if the motor grader operator is highly experienced and trained, yet the cutting edge of the motor grader can show signs of wear due to continuous usage and will have to be replaced eventually. Hence, it is very essential that the blade is regularly inspected and replaced if it shows signs of excessive wear or bending, or if there are missing bolts.
In a nutshell, changing and keeping the blade sharp are two of the most crucial tasks of the motor grader operators. Above mentioned are few tips that the operators should always follow in this regard to achieve maximum efficiency and productivity with their motor graders at the jobsite.
Extending the Life of a Motor Grader
Given that, it is not an unknown fact that all the heavy equipment like motor graders depreciate over the years due to continuous usage. Hence, it becomes imperative to take all the steps that extend the life of the motor grader considerably. The most basic step in achieving this aim is having a proper maintenance plan and applying proper operating techniques.
Here are all the steps that can help you to extend the life of your motor grader at the construction site and get the best possible performance from your equipment…
1. Having the right preventive maintenance plan ready
Regular check-ups are a must to ensure that the motor grader is properly maintained as poorly maintained equipment can result in major faults. Thus, a proper maintenance strategy in place can identify all the faults before they happen. The first step in this direction is formulating a detailed plan having mention of even the minute things. Apart from this, a maintenance schedule should be created and followed religiously. This should have notations on how often each part of the machinery should be inspected for problems, repairs and general maintenance. You should make it a point that during each scheduled service, the machine is examined from top to bottom and special attention is paid to possible weaknesses, defects or component faults. By proactively detecting and repairing flaws, considerable amount of time and money can be saved.
2. Applying condition monitoring system or carrying out checks in between the maintenance schedule:
If you see any change in certain conditions like reaction time, vibration or temperature, it is usually indicative of a developing problem. Hence, it is necessary to carry out checks or perform conditioning monitoring in between the maintenance schedule to rectify the defects as soon as possible. These days, condition monitoring has become much more quick and intuitive. There are sophisticated condition monitoring technologies that carry out the essential functions by performing various tasks to keep the machine in good condition and extend its life.
3. Checking the motor grader regularly:
While having a regular maintenance schedule is important, it is also extremely necessary to maintain and inspect the equipment on a day-to-day basis like after use every day so as to keep it safe, corrosion-free and in the best condition. The day-to-day machine inspection list should include the machine frame, circle, tires, wiring, cylinders, hoses, tools and any areas susceptible to damage or wear and tear. You should always make it a point to check the tires for the right pressure and replace badly worn tires to reduce slippage and resistance caused by bald or under-inflated tires that result in an inefficient use of the machine’s power. Also, you should check for any leaks as it can lead to a big disaster. If you hear any unusual sounds from the engine, then take it as a warning sign. Make it a point to keep the motor grader properly greased during winters. Also, the air filter needs to be regularly checked and cleaned for optimal functioning.
It is a known fact that motor graders are exposed to extreme operating conditions like extremely rocky terrain which puts extra pressure on the cutting edge and leads to fine dust clogging up in the air filter, thereby, compromising the blade slide and turntable functionality. In such a scenario, you may have to readjust your maintenance schedule and carry out maintenance more frequently. This may include checking the blade more frequently for wear or changing the oil filter and lubricating or replacing slide guides and other small moving components.
4. Hiring an experienced motor grader
Being highly technical equipment, motor graders demand well-trained and experienced operators who can handle the equipment wisely, maintain it regularly and identify defects and malfunctioning of the equipment. Thus, an experienced motor grader is always one of the prime factors in extending the life of the motor grader. By using the proper techniques, an experienced motor grader operator can keep the cutting edge sharp and even, position the mouldboard for optimal performance and adjust the tools to align with the conditions. Also, a skilled and experienced motor grader is well-aware of the techniques to reduce wear on the cutting edge.
5. Rebuilding or reconditioning the motor grader to instil second life into it:
Equipment rebuilding or alternatively called as reconditioning is a systematic approach where in a controlled environment, a skilled technician totally rebuilds the equipment and restores the equipment as ‘New’. With this, your machine is re-engineered according to the original specifications, properly tested and thus, is able to work for long. In the equipment rebuilding process, even new software and engineering upgrades are incorporated into the equipment so that it can become even better than before. Thus, reconditioning can help the equipment to deliver better performance and make the machine more reliable at a fraction of the cost of a new machine. In fact, if the rebuilding process is conducted in the right manner by an experienced team, then it gives a second life to your equipment. It is one of the cost-effective, smart and sustainable ways for extending the life of the motor grader.
6. Repairing the motor grader
Repairing is quite an easy and a fast process as essentially it involves identifying the problematic parts and components like what is broken or worn out and fixing or replacing with a new part. It is generally cheaper or more economical way to repair the equipment’s parts and extend the overall life of the equipment. However, the motor grader repair might not be a long-lasting solution for increasing the life of the motor grader.
So, if you possess a motor grader which is being used for years now and is showing the signs of depreciation, then do take the above mentioned steps to extend the life of your equipment considerably and use it happily for some more years without any of the major wear and tear.
Motor Grader Operation and Maintenance Manual
They are undoubtedly very expensive and highly technical equipment. Further, being heavy equipment in nature, they need to be regularly maintained. Also, operators of motor graders need to know about proper operating procedures, safety procedures, preventive maintenance and the overall equipment.
Well, here is a quick manual regarding motor grader operation and maintenance…
1. Before starting to move the motor grader, the blade or mouldboard should be raised.
2. The mouldboard should always be kept straight up and rolling the grader blade forward to make the edge blunt. This also results in better rear visibility.
3. When ripping across a slope, the mouldboard should be kept parallel with the front axle, centred to the frame and lowered close to the ground to provide protection against rolling over.
4. Operating speed of the motor grader highly affects the quality of work. So, while ditching or blading, there should be no hurry. Higher speed can sometimes cause the motor grader to bounce and gauge the surface rather than smoothen it. Sometimes, in extreme cases, bouncing can cause the operator to lose control of the grader, producing a potential accident situation. So, the machine travel speed should be low enough to prevent machine bounce (generally 3 to 5 mph).
5. The motor grader should never be articulated when operating on steep slopes as the grader can roll over and sever personal injury or death can be caused.
6. Articulating the rear frame toward the toe of the mouldboard by 2 to 5 degrees helps reduce motor graders’ tendency to bounce.
7. When using the ripper, the teeth should be lowered into the ground with the grader in motion. If the rear wheels lose traction, operators need to raise the ripper until the wheels regain traction. For especially hard surfaces, the number of teeth should be reduced.
8. When turning around the motor grader, the wheels should always be leaned in the direction in which the turn is being made. This will help the motor grader to turn with ease.
9. Only required amount of downward pressure should be applied to accomplish any task as excessive unnecessary downward pressure on hard and dry surface can cause rapid cutting edge wear and will require more horsepower and fuel, thereby, reducing productivity.
10. When operating, it is imperative to watch both ends of the blade as lifting one end of the blade may cause the other end of the blade to drop about ¼ of that distance.
11. If the circle is not in a level, then the blade setting may change with the angle of the blade. So attention should be paid to it.
12. When not in use, the blade should be put on the ground.
13. The motor grader should be brought to a complete stop before shifting from a forward gear to a reverse gear or from a reverse gear to a forward gear.
14. Before operation the machine, operators need to ensure that the construction equipment is properly equipped with lights, flashing beacons, turn signals etc.
15. Last but not the least, operators need to note and avoid all hazards and obstructions such as over-hands, ledges, slide areas, electrical lines, underground cables, water mains or gas lines while operating the machine.
Motor grader maintenance tips
1. Perform pre-operation and start-up checks daily.
2. Survey under and around the machine before starting it.
3. Walk around the machine for visual inspection of controls, engine, compartment, cooling system, gear boxes, hydraulic parts and other parts for leaks and broken, worn out or missing parts.
4. Make it a point to check for any leaks in the circle drive, dirt and debris build-up in pivot point and blade shift and excessive play, damage, loose or missing parts in the blade linkage.
5. All controls, steering and accelerator should also be tested before starting the equipment.
6. Dirt should be kept out of the engine openings by wiping off dirt and grease before opening filler necks and dipsticks.
7. Do not oil, grease or adjust the machine when the engine is running.
8. The battery ground strap should always be disconnected before making adjustments on the engine or electrical equipment so as to prevent fire hazards, explosions and accidental operation of the starter.
9. The pivot points should be lubricated according to the defined specifications.
10. The blade circle and side shift cylinder should also be cleaned and lubricated with graphite as per the recommendations in the Operator’s Manual.
11. The blade should be checked for loose bolts, amount of remaining cutting edge, wear, damage and loose or missing parts.
12. The hydraulic system should be checked for leaking lines and connections, bent or kinked lines and lines rubbing against other parts. Also, check for loose, worn or broken parts and check hydraulic oil level, filters, hoses and fittings.
13. The cooling system should be checked regularly. This includes checking the coolant level in the radiator, adding coolant if needed and checking the radiator cap, hoses, clamps and fan belts.
14. The belts should be checked for tension and condition.
15. Checks also need to be performed for transmission leaks and gauging transmission fluid level.
16. One should never coast the machine with the transmission in neutral or with the clutch disengaged.
17. Check for damaged tires and wheels should also be performed. Also, it is necessary to check the tire pressure.
18. The lights, back-up alarms and other warning or safety devices should also be checked thoroughly.
19. Checking the brake adjustment and condition is also important.
20. All the wiring, insulation and connections of the equipment should also be checked.
21. All the signals, lights and flags on mouldboard and cab should be thoroughly checked too.
22. All the moving parts of the machine should be lubricated well as they can fail if they aren’t lubricated properly.
Well, above mentioned are just few major points from the very vast motor grader operation and maintenance manual. If you follow these tips, then motor grader’s life can be increased considerably and machine breakdowns can be reduced drastically. So, it is extremely necessary to follow motor grader operation and maintenance manual whenever operating the motor grader.
