Construction and Operation
100
The panel (1) accommodates the key-
switch (17) of the rear axle DL control
and a warning light (16) of the rear axle
DL engaged state.
The key-switch (17) has three positions:
•
Automatic lockup (upper fixed posi-
tion);
•
Forced lockup (lower non-fixed posi-
tion);
•
Lockup disengaged (fixed middle posi-
tion).
In the “Lockup disengaged” position of
the switch (17) the electrohydraulic dis-
tributor (6) is devoid of electric power
supply; the rear axle DL clutch communi-
cates with the drain pipeline, and the rear
axle differential is unlocked.
In the “Automatic Lockup” position of the
switch (17) (when performing the farming
jobs with considerable relative slipping of
the rear wheels), the electrohydraulic dis-
tributor (6) is energized; it directs the oil
flow under pressure towards the rear
axle DL clutch and locks the differential.
Unlocking of the differential will be ef-
fected automatically whenever the steer-
ing wheels will turn through an angle
which exceeds 13° in any direction or
whenever one or both service brakes are
applied.
If temporary lockup of the rear wheels is
required, including situations with turns,
press down the lower part of the key-
switch (17), set it in the “Forced Lockup”
position and retain it therein. When the
key-switch is released, unlocking results
(“Lockup Disengaged”).
ATTENTION!
With the differential lock
mechanism engaged, the tractor
ground speed should not exceed 12
km/h. NEVER operate the tractor on
haulage missions over hard-surfaced
roads with the differential constantly
locked!
