Toro 08162SL Model 30413 Groundsmaster 4100 D Service Manual

Raise Cutting Deck
A four section gear pump is coupled to the piston (trac-
tion) pump. The  third gear pump section supplies  hy-
draulicflowtothelift/lowercontrolvalveandthesteering
control valve. Hydraulic flow from this pump section is
delivered to the two circuits through a proportional flow
divider. The gear  pump takes its suction  from the hy-
draulic reservoir.
To raise a wing deck, the appropriate lift lever on the lift/
lower control valve is pulled to allow valve shift in the lift/
lower control valve. This valve change allows hydraulic
pressure to the piston end of the wing deck lift cylinder
and causes the cylinder shaft to retract, raising the wing
deck. Oil from the rod  end of the cylinder flows to  the
tractionchargecircuit.Whentheliftleverisreleased,the
lift cylinder and wing deck is held in position.
When the cutting deck  is in a stationary position, flow
from the gear pump is by--passed through the lift/lower
control  valve, counterbalance  manifold,  oil filter  and
traction charge circuit.
Anadjustablecounterbalancevalve(CB)inthecounter-
balance manifold maintains back pressure on the deck
lift cylinders to allow some of the cutting deck weight to
be transferred to the traction unit to improve traction. A
reliefvalve located inthelift/lowercontrolvalve   limitslift/
lower circuit pressure to 1500 PSI (103 bar). Excess cir-
cuit flow is routed to the oil filter and then to the traction
charge circuit.
To raise the cutting deck, the center lift lever on the lift/
lower control valve is pulled to allow valve shift in the lift/
lower control valve. This valve change allows hydraulic
pressure to the rod end of the  front deck lift cylinders,
causing the cylinders to retract. As the cylinders retract,
thecutting deckraises.Oilfromthepiston    endofthecyl-
inders returns to the hydraulic reservoir. When the lift le-
ver is released, the lift cylinders and cutting deck is held
in position.

  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.
