Hydraulic Hook-up
!
DANGER
Hydraulic fluid under high pressure can penetrate skin. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Use a piece of cardboard or wood
rather than hands when searching for hydraulic leaks. If
hydraulic fluid is injected into the skin or eyes, it must be
treated by a doctor familiar with this type of injury within a
few hours or gangrene may result. DO NOT DELAY.
There can be two dual hydraulic hose hook-ups. They are
hydraulic motor for chute rotation and optional hydraulic
cylinder for deflector adjustment. Be sure tractor
reservoir is filled properly before operating hydraulic
motor and/or hydraulic cylinder. If tractor reservoir is low
on hydraulic fluid, there is a chance of drawing air into the
system causing jerky or uneven movements.
Hydraulic Motor (Chute Rotate)
Refer to Figure 2-10 on page 19:
1. Locate hydraulic motor hoses (#9) and connect quick
disconnect couplings to a single duplex outlet on the
tractor. This is best if connected to the control lever
closest to the operator.
2. Set tractor control lever in the non-float position.
3. Cycle hydraulic system by rotating chute until it points
to the left at 90
o
to the direction of travel and then
rotating chute 180
o
in the opposite direction. Do this
several times to purge hydraulic motor of air.
4. It is best if chute rotates to discharge to the right
when pushing control lever on the tractor forward. If
chute does not rotate in the direction desired, switch
quick disconnect couplings at the duplex outlet.
Hydraulic Cylinder
(Deflector Adjustment Option)
Refer to Figure 2-10 on page 19:
1. Locate hydraulic cylinder hoses (#8 & #10) and
connect quick disconnect couplings to a single
duplex outlet on the tractor. This is best if connected
to the control lever next to the hydraulic motor control
lever.
2. Set tractor control lever in the non-float position.
3. It is best if deflector adjusts up when pushing control
lever on the tractor forward. If deflector does not
adjust in the direction desired, switch quick
disconnect couplings at the duplex outlet.
4. Cycle hydraulic system by extending and retracting
the cylinder several times to purge hydraulic cylinder
of air.
5. Purge hydraulic system if hydraulic cylinder operates
unevenly after cycling it several times:
a. Loosen elbow fitting at the rod end of the hydraulic
cylinder.
b. Slowly retract and extend hydraulic cylinder until
all trapped air is purged from the cylinder and
hose.
c. Retighten elbow fitting.
d. Loosen elbow fitting from the base end of the
hydraulic cylinder.
e. Slowly retract and extend hydraulic cylinder until
all trapped air is purged from the cylinder and
hose.
