Mow Circuit
The reel motor drive pump is directly coupled to the trac-
tion pump which is belt driven by the engine. Taking its
suction directly from the reservoir, the reel motor drive
pump supplies oil flow to the hydraulic manifold block
and to the reel motors.
compensated by the logic cartridge valve (LC1). Any ex-
cess flow above what the speed control valve is set for
is bypassed to the reservoir through the logic cartridge
valve. With the backlap valve (MD1) in the MOW posi-
tion, oil flows through the valve and reel motors which
are connected in series. Oil flows through the right, cen-
ter, and then left reel motor as it turns the motors in the
mow direction. The oil then returns to the reservoir.
With the engine running and the cutting unit switch in the
DISENGAGED position, oil flows into inlet port (P1) and
through deenergized solenoid valve (S1) bypassing the
reel motors. Oil then flows directly back to the reservoir
through the oil cooler.
Relief valve (R1) limits system pressure and is set at
3000 PSI (207 bar). When the valve opens, oil is di-
verted back to the reservoir.
When the cutting unit switch is in the ENGAGED posi-
tion with the engine running, solenoid valve (S1) is ener-
gized and shifted, hydraulic system pressure builds up,
and flow is diverted to the reel motors. Oil flow from port
(P1) flows through the 11 position reel speed control
valve. Flow across the speed control valve is pressure
Backlapping operation is the same as mowing opera-
tion, except for the position of the backlap valve (MD1).
When the backlap valve is in the BACKLAP position, oil
flow is directed through the left, center, and then right
reel motor as it turns the motors in the backlap direction.
