The backhoe’s mainframe fits into rear mounting brackets installed on the tractor. This provides the following important features:

Vertical or side-to-side movement is virtually eliminated, providing more stability. The design of the mainframe also positions the entire backhoe close to the tractor. Operators are also able to benefit from the total weight transfer between the backhoe stabilizers and loader bucket.
The tractor chassis is protected because the mainframe integrates the tractor and backhoe combination together as one.
Once the mounting frame is installed, attaching and detaching is quick and easy.
