REAR GEARCASE (DIFFERENTIAL)

General Operation

The RANGER 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 - Locked
Differential - Unlocked
When the "Unlocked" option is chosen on the selector, the rear
differential becomes unlocked for tighter turns. An electrical
solenoid mounted on the rear axle housing actuates the shift
yoke and slides the clutch gear to lock and unlock the rear axle
housing.
When switch position is set
to "Unlock", the solenoid is
powered and the
plunger extends
to disengage the
clutch gear and
unlock the
axle housing.
When the clutch gear is unlocked the rear axle becomes a
differential. When it's locked it becomes a solid rear axle
increasing traction. (See images below)
