has leaked from the hydraulic circuit (a small oil leak can
change settings).

- Shift the mowing unit lift cylinder directional control
valve in float position.
- Open valve (position (a)).
- Release pressure until the gauge needle reads 0.
- When the pressure reaches 0 bar (0 psi) bar on the
pressure gauge, close the valve (position b.
