HYDRAULIC SYSTEM ______________________________________________________
The hydraulic system on this vehicle is referred to as a
“live” system. This means the hydraulic pump operates
whenever the engine is running.
The operation of the hydraulic system is determined by
the selector valve. When the selector valve knob (AA) is
pushed down, the hydraulic lift system is active, and the
remote hydraulics are disabled. When the selector valve
knob is pulled up, the remote hydraulics are active, and
the hydraulic lift system is disabled.
Refer to the decal on the hydraulic connector cover to
determine proper accessory connections. Always stop
the engine before changing hydraulic connections
Hydraulic Lift System:
When hydraulic lift system is active, the system is
controlled by the lift valve. The lift valve includes two
check valves and a relief valve. The check valves prevent
unwanted movement of the cylinder.
The lift valve has four positions, raise, neutral, lower, and
float. The handle (AB) will automatically return to the
neutral position when released from the raise or lower
position. When in the float position, the handle must be
pushed forward and to the left before it will return to the
neutral position.
1.
Pulling back on lift valve handle (AB) will extend the
cylinder, raising the utility vehicle bed.
2.
Pushing forward on lift valve handle (AB) retracts
the cylinder, lowering the utility vehicle bed.
3.
Pushing lift valve handle (AB) forward and to the
right will place the lift valve into the float position.
This position bypasses the check valves, which will
allow the accessory to follow the ground contour,
even in undulating terrain.
To use the utility vehicle bed cylinder, connect cylinder
hose (4) to coupler (1), and lift valve hose (2) to coupler
(3). To use an accessory cylinder, connect accessory
cylinder hose (5) to coupler (1), lift valve hose (2) to
accessory cylinder hose (6), and utility vehicle bed
cylinder hose (4) to coupler (3).
Remote Hydraulic System:
The remote hydraulic system is used to operate
accessories such as the Hydraulic PTO, Core Harvester,
Top Dresser, or remote hydraulic powered hand tools.
To prevent overheating and/or damaging the hydraulic
system, always keep the remote hydraulic system
connected in a closed loop. Connect hose (8) to coupler
(7) when accessory is not connected.
To use a hydraulic accessory, connect accessory hose
(9) to hose (8), and accessory hose (10) to connector (7).
Refer to the instructions that come with the accessory
from proper operation
