RESERVOIR
Mnt-FL-0080
The reservoir stores hydraulic system oil. The breather cap which is mounted on top of the reservoir prevents
a pressure buildup or vacuum from occurring in the tank as oil level changes. Their is also an oil filler cap
which is used to fill the reservoir with oil. To help prevent dirt from entering the tank, clean the top of the
reservoir before removing the cap. THE BREATHER CAP HOLDS APPROX 11 PSI PRESSURE IN TANK.
REMOVE FILLER CAP SLOWLY
The oil level sight glass is located on the side of the reservoir. The oil level should be even with the sight glass
and checked with the cutter unit in the transport position. The oil temperature should not exceed 180 degrees
F.
The oil return hoses are connected to the hydraulic filter on top of the reservoir. Oil is returned from cutter unit
cooling tubes and filtered before entering the hydraulic reservoir.
SOLENOID CONTROL VALVE
A. CONTROL VALVE
B. SOLENOID
The solenoid control valve directs oil flow from the
hydraulic pump. When the mower ON/OFF switch
is in the "ON" position, the solenoid is energized
and the spool within the valve is positioned to direct
oil to the cuttershaft motor.
When the mower ON/OFF switch is in the "OFF"
position, oil pressure within the valve pushes the
spool back which allows the oil to circulate through
the cutter unit before returning to the reservoir.
