OPERATION
Differential Operation Modes
The 4X4 rear axle is equipped with a lockable differential that allows
the operator to choose between an open differential or a closed differen-
tial.
AWD
Press the top of the rocker switch to
engage All Wheel Drive (AWD). When
in AWD, the rear wheels rotate at the
same speed. The front wheels also rotate
at the same speed. See page 57 for AWD
operating instructions.
2WD/Rear Differential Locked
Move the rocker switch to the center
position to lock the differential and oper-
ate in two wheel drive (2WD). Locking
the differential in slippery or low traction
conditions helps improve traction. When
the rear differential is locked, both rear
wheels rotate at the same speed.
OFF/Differential Unlocked
Press the bottom of the switch to unlock the differential and allow the
rear drive wheels to operate independently (1WD). When the rear differ-
ential is unlocked, the rear wheels can rotate at different speeds. Unlock
the differential to make maneuvering easier and minimize damage to
turf.
NOTICE: Damage to the differential can occur if it is engaged while the vehicle
is traveling at high speeds or while the rear wheels are spinning.
Slow the vehicle to nearly stopped before engaging the differential.
