11.3.12 Adjusting the restoring force of
the hydraulic stone protection
system (additional equipment)
Set the restoring force so that the plough
bodies sit firmly in the ground but can
deflect upwards slightly over stones.
If the deflection of the plough bodies is
insufficient, increase pressure gradually.
Minimum pressure:
120 bar (factory setting)
Maximum pressure:
170 bar
Connect the hydraulic hose of
the automatic stone protection system
to a single-acting control device on
the tractor.
Open the stopcock (
1
); set the hydraulic
pressure with a manometer (
2
).
Once the pressure has been reached,
close the stopcock.
