From the transport position:
- Pull on cord to release latch.
- Activate the transport/work cylinder control valve in
the "pivot into work" position.
- Activate the transport/work cylinder control valve in
the "lift into headland turn" position.
The machine takes up the headland turn position.
Measure and adjust the height of the hitch pins until the
same measure is obtained on each side:
- Note the difference in height between the two hitch
pins.
Place the machine in transport position:
- Pull on cord to release latch.
- Activate the transport/work cylinder to bring the
mowing unit in transport position.
- Rest cutterbar on the ground.
Adjust the tractor left levelling rod according to the
difference in height.
Place the machine in headland turn position.
Check the difference in height between the 2 hitch pins.
Proceed the same way to obtain identical (A) and (B)
heights.
-
For an optimum adjustment, when the machine
is in headland turn position, the mowing unit
must never be in horizontal position or sloping
downwards.
