3. Operation
2. Press the lifting/lowering switch or the lifting/lowering push buttons to lift or
lower the lower links.
The lower links lift or lower for as long as you press the switch/button.
3. Connect the implement.
IMPORTANT: Make sure that the implement is correctly attached and that it
does not hit the other parts of the tractor when lifted to the selected transport
height.
Side limiters must be locked with pins when transporting implements that are
carried by the three-point linkage.
4. Follow the implement manufacturer's instructions.
Correct adjustment of harrows, ploughs and cultivators reduces the required
tractor power. An incorrectly adjusted plough, for instance, creates a badly
shaped furrow, tends to twist the tractor away from the driving direction,
increases fuel consumption and wastes power due to wheel slip.
5. Activate the linkage with the lift/stop/lower switch.
After using the lifting/lowering switch or the lifting/lowering push buttons, you
have to activate the position control system again.

Using quick couplings for lower links

DANGER: When attaching or releasing implements, always stand
outside the implement and beside the tractor. Never stand on the
implement or between the implement and the tractor.
WARNING: The linkage movement speed increases when the
lifting/lowering switch is pressed for a longer time.
CAUTION: The lifting height selector does not limit the lifting
height when the lifting/lowering switch or the lifting/lowering push
buttons are used.
DANGER: The implement has to be mechanically connected to
the tractor (the lower links and the top link) before connecting the
quick couplings.
DANGER: Make sure that at least 20% of the total combination
weight rests on the front wheels. When needed, use a sufficient
number of front ballast weights.
DANGER: Clean the quick couplings and ball joints before attaching
an implement. There is risk that the implement is not attached
properly.
