Mow
Hydraulic flow for themow circuit is supplied by twosec-
tions of the gear pump. The gear pump section closest
to the piston (traction) pump supplies hydraulic flow to
the side cutting decks, while the next gear pump section
supplies the front cutting deck.
Returnoilfromthedeckmotorsisdirectedtotheoilcool-
er and oil filter. Deck motor case drain leakage returns
to the hydraulic reservoir.
Maximum mow circuit pressure is limited at each deck
by a relief valve (RV1) in the hydraulic manifold. The
front and left deck relief valves are set at 3000 PSI (207
bar)andtherightdeckreliefvalveissetat2000PSI(137
bar).
Each cutting deck is controlled by a hydraulic manifold
equipped with a solenoid control valve (S), bypass car-
tridge (LC1), brake cartridge (LC2) and relief cartridge
(RV1).Whenthe thedeck solenoid valve (S)is notener-
gized (PTO switch OFF), hydraulic flow by--passes the
deck motor through the bypass cartridge (LC1). When
the PTO switch is turned ON, the solenoid valve (S) en-
ergizes, causing a shift of the by--pass cartridge (LC1)
andallowinghydraulicflowtothedeckmotor.Brakecar-
tridge (LC2) and relief cartridge (RV2) control the stop-
ping rate of the blade when the solenoid control valve is
de--energized as the PTO switch is turned OFF.
Circuit pressure can be measured at port (G) of the hy-
draulic manifold for each cutting deck.
