3. Operation
•
Activate the PTO automatic start/stop by pressing the button for rear PTO
automatic start/stop.
You can activate the PTO automatic start/stop only if the PTO is engaged
and the linkage is not in the transport position. The automatic start/stop
cannot be active together with the U-pilot.
The light in the button is lit when the PTO automatic start/stop is activated.
The PTO is stopped automatically when you have activated the automatic
start/stop and set the lift/stop/lower switch to the transport position and when
the linkage has raised the lower links to the position of at least 70% of the
maximum lifting height. After an automatic stop, the light on the button and
the display symbol start to blink, indicating that the PTO automatic start is
standing by.
The automatic start takes place only if the PTO has been stopped with the
automatic start/stop. The PTO starts automatically if the driving speed is
between 1 and 25 km/h, the linkage is lowered with the lift/stop/lower switch
and the lower links have been lowered to 90% of the maximum lifting height.
•
Deactivate the automatic start/stop in any of the following ways:
•
•
•
The automatic start/stop is also deactivated if the driving speed at the
moment of lowering the linkage is outside the speed limits 1–25 km/h. When
the automatic start/stop is deactivated, the button is not lit.

Proportional ground speed power take-off
The proportional ground speed power take-off (PTO) is optional.
The proportional ground speed PTO is primarily used in the A and B speed
ranges. The proportional ground speed PTO is designed for the highest torque
values of the speed ranges A and B. In the speed ranges C and D, the
transmission shaft rotates faster, and therefore, the ground speed PTO must be
disconnected. The faster rotating speed may damage the propeller shaft between
tractor and implement. The trailer should be equipped with a means of
disconnecting the drive from the trailer.
IMPORTANT: Do not use the creeper gear together with the proportional ground
speed PTO to increase traction force. There is a risk of damage to the
transmission.
The proportional ground speed PTO can be engaged if the driving speed is 2
km/h or less. There is no speed limit for disengaging the ground speed PTO.
Before using a trailer with a powered axle, make sure that the drive is compatible
with the PTO of the tractor. The speed of the trailer should be 0-3% lower than
driving speed of the tractor.
Press the button for rear PTO automatic start/stop.
Use the switch for rear PTO on the armrest.
Keep the linkage raised, that is, in the standby position for at least 90
seconds.
CAUTION: When using the proportional ground speed PTO, the speed
of the PTO shaft varies according to the transmission speed of the
tractor. When the tractor is reversed, the PTO shaft also rotates in the
reverse direction.
