Operating Tractor
Operate tractor engine at the proper speed to reduce hydraulic system heat buildup in hot conditions.
-
Operate engine at the following maximum speeds when using backhoe in hot conditions:

Faster engine speeds result in faster backhoe movement. When operating where precise movements of the backhoe are required, throttle back on engine speed. This will slow down the speed of the backhoe movement.
Digging forces and breakout forces are the same at any digging rpm. The forces are a function of hydraulic pressure only.
