Mow Circuit
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 wing decks, while the next gear pump section sup-
plies the center deck.
The solenoid valve (S) for each wing deck is de--ener-
gized any time the wing deck is raised.
Returnoilfromthedeckmotorsisdirectedtotheoilcool-
er and oil filter. Deck motor case drain leakage returns
to the hydraulic reservoir.
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.
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).
Circuit pressure can be measured at port (G) of the hy-
draulic manifold for each cutting deck.

  1. At only 700mm wide the Mini Dumper is even at home on tight access
    sites. No need to grunt, groan, and force the
    mower about the yard. The US will be getting a revised 2011 Jeep Wrangler but the diesel option will not be offered in the United States.
