3. ADJUSTMENTS AND DRIVING
TURNING
Fig. 3-10 When turning in the field, use the lifting cylinder A on the boom (Easy Lift).
THE BREAK-AWAY MECHANISM
A mechanical stone release enables the cutting unit to swivel backwards in case of
collision with foreign matter.
When the stone release is activated, disengage the power take-off and stop driving
immediately.
Disengagement is important as the PTO shafts will otherwise be exposed to a large
angle due to the backwards movement of the cutter bar.
The stone release can be reactivated by reversing the tractor with lowered cutting
unit.
The factory setting of the stone release is adjusted to most conditions.
Fig. 3-11 Tighten the spring to 145 mm (5 mm = 3 turns of the nut).
If the break-away mechanism is activated too often, it is of course possible to tighten
the initial tension of the spring. Never tighten the spring so much that it blocks the
mechanism due to insufficient spring travel.
SECURING AGAINST OVERLOAD
IMPORTANT: The tractor driver can secure the transmission against overload!
When using the machine, the following should be considered:
1) Always start the machine with the engine running at low speed. This especially
applies to tractors with electro-hydraulic connection of the PTO shaft.
2) The machine must be in working position when starting.
3) A sudden increase in the number of RPM of the machine, e.g. when driving into
the field or after turning in the field should also happen with the machine close
to working position.
4) Listen to the RPM of the tractor when working in the field. If the RPM falls slowly
or is suddenly reduced it may be a sign of overload of the transmission due to
too high driving speed or foreign matter in the cutting unit. In this case, the
friction clutch will slip and you should disconnect the PTO immediately and let
the machine “rest”.
