DIFFERENTIAL LOCK
FIG. 4-7: Differential lock pedal, 1, should only be de-
pressed when required as steering ability is greatly
reduced.
To engage differential lock, allow rear wheel move-
ment to stop. Depress lock pedal.
To disengage differential lock, release differential
lock pedal. Lock pedal should normally return to the
“OFF” position;
NOTE: On occasion, differential lock pedal may
remain, engaged due to torque difference
exerted by rear wheels, in this case, depress
the HST pedal while Tractor’s slowly in mo-
tion to release the pedal.
CAUTION: DO NOT use differential lock
on hard surfaces or when transporting
unit. DO NOT, engage with rear wheel(s)
spinning as severe damage may result.
DO NOT attempt to steer with the deffer-
ential lock engaged.
FOUR-WHEEL DRIVE
FIG. 4-8: Four-wheel drive models have a mechani-
cally driven front axle. Engagement and disengage-
ment of front drive axle is controlled by lever, 1, on
right side of tractor.
IMPORTANT: Prior to engaging or disengaging
4WD, Tractor stopped.
FIG. 4-9: When front axle is engaged, ground speed
of front tires is slightly faster than the ground speed of
rear tires. This is to assist steering when 4-wheel drive
is selected.
For this reason, front axle must be disengaged when
Tractor is transported of operated on a hard, dry sur-
face. Failure to do so will result in rapid wear of front
drive tires and possible driveline damage.
IMPORTANT: Always disengage front drive axle
when operating in, conditions with
minimal wheel slippage (DRY OR
HARD SURFACES). If tire replace-
ment is neccessary, identical replace-
ments must be installed to maintain
correct front/rear axle ratio.
