Fig.
14. Valve settings on the hydro - pneumatic suspension
The valve which is set for operation (hydro-pneumatic suspension) is shown on Fig. 14.
Itshould be remembered that this valve must be closed after finishing operation. In the event when
the system pressure is greater than 0 (manometer reading) and the mower is at rest, the valve must
always be in the "Rest" position. Changing it to the "Work" position can cause sudden lifting of the
hitch which will make connecting the mower to the tractor again very difficult.
