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.
- The hydro-pneumatic accumulator system also
operates the "safety breakback " function.
- In case an obstacle is struck:
• The suspension pressure increases in order to
decrease the ground pressure.
• The mowing unit can pivot up to 18° to the rear.
• Once the obstacle is passed, the mowing unit
automatically regains its initial position.
To check the ground pressure:
- Place the machine in working position.
- Check that the chassis height is correct
H = 550 mm (1’10’’).
- Check the pressure given on the gauge:
• NORMAL operating pressure = 66 bar (957 psi).
• MINIMUM operating pressure = 55 bar (797 psi).
• MAXIMUM operating pressure = 83 bar (1203 psi).
- The pressure must be adapted to the nature and
moisture degree of the ground.
The ground pressure adjustment determins the
safety breakback adjustment:
Example: when the pressure in the gauges
increases, the mowing unit ground pressure
decreases and the breakback force increases.
In case an obstacle has been struck, check
that the mowing unit has not been damaged.
Never adjust machine to a pressure not
comprized between these limit values.
