8.2.2 Ground pressure
The mowing unit suspension is obtained by 2 hydro-
pneumatic accumulators.
By modifying the pressure in the accumulators, the
mowing unit ground pressure is altered.

To check the ground pressure
- Place the machine in working position.
- Lower the tractor's lift linkage to tension the check
chains.
- Check that the chassis height is correct:
500 mm (1’8’’).
- Check the pressure given on the gauge:
• NORMAL operating pressure = 75 bar (1088 psi).
• MINIMUM operating pressure = 60 bar (870 psi).
• MAXIMUM operating pressure =
100 bar (1450 psi).
The pressure must be adapted to the nature and
moisture degree of the ground.
