REAR GEARCASE

General Operation

The rear gearcase has three traction operational modes: AWD,
Differential Lock, and Differential Unlock. Locking the rear
differential is beneficial in low traction and rough terrain
conditions. Unlocking the rear differential makes maneuvering
easier and minimizes damage to turf and sensitive terrains.
AWD
Differential - Lock
Differential - Unlock
When "Differential-Unlock" is selected on the switch, the rear
differential becomes unlocked for tighter turns. An electrical
solenoid mounted in the rear gearcase housing actuates the shift
yoke. The solenoid plunger extends out to move the shift yoke
and slides the clutch gear away from the engagement dogs that
are attached to the differential gear assembly. This unlocks the
rear differential.
When switch position is set
to "Unlock", the solenoid is
powered and the
plunger extends
to disengage the
clutch gear and
unlock the
differential.
Shift Yoke
Differential - Unlock
When "Differential-Lock" is selected on the switch, power is
removed from the electrical solenoid allowing the solenoid
plunger to retract. Spring tension moves the shift yoke back into
place and engages the clutch gear into the engagement dogs that
are attached to the differential gear assembly, locking the rear
differential as a solid rear axle.
When switch position is set
to "Lock", power is removed
from the solenoid and spring
tension retracts the
plunger to engage
the clutch gear
and lock the
differential.
