DIFFERENTIAL LOCK
FIGS. 4-29 & 4-30:
When the differential lock, 1, pedal
or lever is lowered, both sides of the rear axle are
locked together to ensure traction to both rear wheels.
This is especially important when operating in loose
soil or slippery conditions.
To engage the differential lock - Depress the clutch
pedal or lever and allow all rear wheel movement to
stop. Depress the lock pedal or lever and slowly en-
gage the clutch.
IMPORTANT: DO
NOT engage with rear wheel (s)
spinning as severe damage may re-
sult.
To disengage the differential lock - Depress the clutch
pedal and release the differential lock pedal or lever.
The lock pedal or lever should normally return to the
“off” position.
NOTE: On
occasion, differential lock pedal or lever
may remain engaged due to torque differ-
ence exerted by rear wheels. In this case,
tap brake pedals alternately while tractor is
slowly in motion to release the pedal.
CAUTION: When differential lock is
engaged, steering ability of tractor will
be greatly reduced. Disengage before at-
tempting a turn.
CAUTION: DO NOT use differential lock
on hard surfaces or when transporting
the tractor.
FOUR-WHEEL DRIVE
FIG. 4-31:
The four-wheel drive shift lever, 1, engages
and disengages the drive for the front axle. With the
lever down, the front axle (4WD) is engaged. With the
lever up, the front axle is disengaged, and power is
available to both front and rear axles.
NOTE: 4WD indicatior lamp will be illuminated when
you push down the 4WD control lever.
IMPORTANT: Depress main clutch pedal and stop
tractor before engaging or disengag-
ing four-wheel drive.
When front axle is engaged, ground speed of front
tires is slightly faster than the speed of the rear tires.
This is to assist steering when four-wheel drive is
selected.
For this reason, the front axle must be disengaged
when the 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.
