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 differential.
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 41 for AWD operating instructions.
2WD/Rear Differential Locked
Move the rocker switch to the center position to lock the
differential and operate 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 differential 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.
