In adjustable valves, the position lock is always disengaged when the tractor
engine is shut down. This prevents unexpected hydraulic movement and
decreases the engine load during start. The basic valve 1 does not have this
function. The floating position stays engaged, regardless whether the tractor
engine is running or shut down.
The tractor is equipped with an auxiliary hydraulic return coupling 1/2” (12,5 mm).
When the front linkage has been connected to the rear valve, the tractor is
equipped with the front linkage shut-off valve.
