OPERATION

DIFFERENTIAL LOCK
FIG. 5-11: Differential lock pedal, 1, should only be
depressed when required as steering ability is greatly
reduced.
To engage differential lock, depress clutch pedal and
allow all rear wheel movement to stop. Depress lock
pedal and slowly engage the clutch.
To disengage differential lock, depress clutch pedal
and 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, tap brake pedals
alterna-tively while Tractor is slowly in motion 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.
FOUR-WHEEL DRIVE
FIG. 5-12: Four-wheel drive models have a mechanically
driven front axle. Engagement and disengagement of
front drive axle is controlled by lever, 1.
IMPORTANT: Prior to engaging or disengaging 4WD,
clutch pedal must be depressed and
Tractor stopped.
FIG. 5-13: When front axle is engaged, ground speed of
front tires will vary from ground speed of rear tires. This
is to assist steering when four-wheel drive is selected.
For this reason, front axle must be disengaged when
Tractor is transported or operated on a hard, dry surface.
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
w h e e l s l i p p a g e ( D RY O R H A R D
SURFACES).
If tire replacement is necessary, identical
replacements must be installed to
maintain correct front/rear axle ratio .
