How to Replace Backhoe Bucket Teeth
On a typical construction site, the backhoe loader operators usually use all the three of its components to get the job done. These include tractor, loader which is attached in the front and the backhoe which is attached at the back.
Out of all the three, backhoe is the main component of the Backhoe Loader (BHL) and is used to dig up hard and compact material, usually earth or to lift heavy loads. This backhoe again constitutes three segments i.e., boom, stick and bucket. The backhoe can dig all sorts of holes but is especially suited for digging ditches.
In this task of digging ditches, penetrating and breaking of compacted dirt and rock, the bucket teeth provide an edge to the backhoe bucket. They are fitted into the corresponding slots on the bucket and are held firm with the pins.
Why backhoe bucket teeth need to be replaced often?
Given the heavy tasks they perform, the bucket teeth are subjected to high wear and tear. Thus, they are designed in such a manner that they can be easily and inexpensively replaced. In many cases, there are tooth bars instead of individual teeth in the bucket. In these types of equipment, the entire tooth bar has to be removed for replacing the teeth.
