Hydraulic system, components
Pressure to the hydraulic system is provided by the
hydrostatic pump. A pressure limiting valve limits
the maximum system pressure to about 45 bar/
630 PSI.
A hydraulic oil filter of the spin-on type is used to
filter impurities. There is also a filter in the
hydrostatic transmission. Both filters work together
to keep the system as clean as possible.
The control valve is a slide valve. The lever is found
in the lever housing to the rear and is connected to
the slider. Pressure supply and exhaust takes place
via the valve block. Hydraulic oil for the lift cylinder is

provided via two hoses. The hose's nipple for the
cylinder's piston side is equipped with a throttle.
Between the slider and the throttle, there is a
mechanically controlled return valve. The purpose
of the rear valve is to contain the oil so that the
cutting unit doesn't lower when the lever is not
activated.
The lift cylinder is a double-action hydraulic cylinder,
and is connected to the lever housing's shaft.
The power steering is described under "Steering" on
page 22.
