Digging Safely

TY1226

c CAUTION: Avoid injury! To dig safely: • Sit in backhoe seat. • Lower stabilizers to ground. • Keep loader bucket low or on ground.

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:

Gear Drive Tractor...........................................2400 rpm

Hydrostatic Drive Tractor.................................2700 rpm

Faster engine speeds result in faster backhoe movement. When operating where precise movements of the backhoe are required, slow the engine to slow backhoe movement.

Digging forces and breakout forces are functions of hydraulic pressure only, and are the same at any digging rpm.
