Controls and Instrumentation
Rear PTO control (for tractors
equipped with a hydraulic lift)
To engage the rear PTO, the key switch
(4) and push-button switch (5) located on
the panel above the right control board
are used. The switch (4) has two fixed
positions:
• “PTO ON” – when pressing the
lower part of the key switch;
• “PTO OFF” – when pressing the up-
per part of the switch.
To engage the PTO:
• Press the lower part of the key switch;
• Shortly press push-button switch (5).
Control lamp (3) will be on and PTO
shank will start rotating.
NOTE: On stopping the engine, the PTO
is disengaged automatically.
To disengage the PTO, press the up-
per part of the switch. The pilot lamp
will become dim.
ATTENTION! The PTO engagement
operations shall be only performed with
the engine running.
Rear axle differential lock control (for
tractors equipped with a hydraulic lift)
The differential lock (DL) is controlled
with key (1) having three positions:
• “DL OFF” – mid fixed position to be
used when performing the transport
works on the hard surface roads;
• “DL ON automatically” – by pressing
the upper part of the key (1). Fixed
position. It is to be used when per-
forming the works with substantial rear
wheel skidding.
In the automatic mode, the rear wheels
are locked during the straight-line motion
and unlocked when turning the guide
wheels at the angle exceeding 13 in any
direction.
• “DL ON forcedly” – by pressing
the lower part of the key (1). Fixed posi-
tion. It is to be used for locking shortly
the rear wheels when overcoming the
obstacles. On releasing the lower part of
the key, it returns to the mid position. On
activating the DL, the pilot lamp (2) lights
up, which becomes dim when unlocking
the DL in the automatic mode and on set-
ting the key (1) to the mid position.
ATTENTION! Activate the DL under the
increased skidding conditions when per -
forming the field and transport works.
IMPORTANT! Disable the D L at the
tractor motion speed exceeding 1 0 km/h.
Otherwise, the service lift of the power
transmission would be shortened and
the tractor control would be impeded.
The forced locking shall be used shortly
only to overcome road obstacles.
