The differential lock can be selected in order to override the normal operation of the front axle differential. The differential lock will help maintain traction when the ground conditions are soft or slippery. When the differential lock is selected, torque is transmitted to both wheels even though one wheel may not have traction.

The differential lock control is operated by a spring return switch on the dash panel. Push the top of the switch and hold the switch in order to engage the differential lock. In order to disengage the differential lock, release pressure from the accelerator pedal and release the switch.

NOTICE
Use the differential lock only in conditions where wheel spin has, or will be encountered. If wheel spin has already developed, release pressure from the accelerator pedal and allow the engine speed to fall sufficiently to stop wheel spin before engaging the differential lock. Failure to follow this procedure can result in machine damage. Keep steering maneuvers to a minimum when the differential lock is engaged. Steering maneuvers with the differential lock engaged can result in machine damage.

The differential lock should only be engaged with all of the wheels in the straight ahead position. The differential lock should only be engaged when the machine is stopped.
