TRANSMISSION SERVICE
DIFFERENTIAL OPERATION
Transmissions equipped with Turf Mode have two
traction
operational
modes:
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 terrain.
When
“Differential-Unlock”
is
selected,
the
rear
differential becomes unlocked for tighter turns. An
electrical solenoid mounted in the rear portion of the
gearcase actuates the shift fork. The solenoid plunger
extends out to move the fork and slides the engagement
dog away from the side gear that is part of the planetary
differential assembly. This unlocks the rear differential.
The rear drive shafts are now dependent on the
differential allowing for tighter turns.
When “Differential-Lock” is selected, power is removed
from the electrical solenoid allowing the solenoid plunger
to retract. Spring tension moves the shift fork back into
place and mates the engagement dog to the side gear
that is part of the planetary differential assembly. This
locks the rear differential as a solid rear axle, increasing
traction.
