Putting into service
Pressurizing the hydraulic ground pressure
circuit
The optimal suspension is obtained with the mowing unit
ground pressure set to the minimum, in such a way that
the unit does not lift off the ground when going over
irregular ground contours.
- Couple the machine to the tractor
• ( See section: Coupling the machine ).
- Lower tractor lift linkage until obtaining a distance of
450 mm (1’5’’) between the hitch pin pivot point and
the ground.
- Open valves (1) using 18 mm box spanner:
• (a) Hydraulic valve bank.
• (b) Ground pressure circuit.
- Activate the transport/work cylinder control valve in
the "pivot into transport" position.
- Check the pressure increase indication on the gauge.
- Shut-off valve of the hydraulic valve bank when the
pressure reaches 105 bar (1523 psi) on the gauge
The machine hydraulic ground pressure
circuit is factory set without pressure.
Conventional pressure = 105 bar (1523 psi)
Hydraulic valve:
- Valve open (a)
- Valve closed (b)
Ground pressure circuit valve:
