SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION

DIFFERENTIAL LOCK
Four wheel drive tractors have a differential lock
installed in the front and rear axles to lock all four
wheels together in conditions where wheel slip may
occur. Two wheel drive tractors have a differential
lock in the rear axle only.
The differential locks are controlled by a spring
centered rocker switch on the console to the right of
the seat.
The differential lock(s) may be operated in manual
mode or automatic mode. To confirm mode selected,
the appropriate symbol on the switch will illuminate
when engaged.

WARNING
Avoid using the differential lock at speeds above
8km/h (5 MPH) and never at speeds above 15 km/h
(9 MPH) or at any time when turning the tractor.
When engaged, the differential lock will make
steering the tractor very difficult.
IMPORTANT:
If wheel spin is encountered, reduce
engine speed before engaging the differential lock,
to avoid shock loads to the transmission.
Operating in Manual Mode
In slippery conditions, momentarily depress the
bottom of the switch (1) Figure 150 , to lock both
wheels together. The differential lock(s) will engage
and a warning light in the switch and on the
instrument panel (2) will light up.
When one or both brake pedals are applied or if the
switch is returned to the off (central) position,
disengagement will occur and the warning lights in
the switch and instrument panel will go out.
Alternatively, depress the bottom of the switch again
to disengage the differential lock(s).
NOTE: The lock(s) will remain engaged until traction
at the wheels equalises.
