7.
Restart tractor and back up to cutter hitch until hitch
bushing (#10) aligns with holes in swivel clevis (#9).
8. Shut tractor down properly before dismounting.
9. Insert 1" x 6 1/2" GR5 hex bolt (#2) through swivel
clevis (#9) and hitch bushing (#10). Secure bolt with
locknut (#1). Tighten locknut snug to remove all play.
Do not torque 1" locknut at this time.
10. Lower park jack (#3) until hitch weight is supported
by the drawbar.
11. Relocate park jack (#3) from hitch frame to storage
base and secure with detent pin (#8). Ensure base of
park jack is level with, or lower than the jack crank
head. See cover picture for correct positioning.
12. Attach hitch safety chain (#4) to tractor. Adjust length
to remove slack except what is necessary to permit
turning. Securely lock chain hook to the safety chain.
Hydraulic Hook-up
The required number of duplex outlets on the tractor is
dependent upon how the cutter is set-up. The standard
cutter is equipped with two hydraulic cylinders with one in
the center for lifting the cutter and one for folding the
wing. The center lift cylinder is set up for single-action
(one way) operation. The wing can be set up with single-
action (one way) or dual-action (both way) operation.
Each duplex outlet on your tractor can perform just one
operation. One outlet is needed for lifting the cutter and
one for folding the wing. It is highly recommended to
connect the wing fold hose to a duplex outlet with float
capabilities and use the float when in field operation.
The black handled hose is for the lift cylinder. A red
handled hose is for right wing fold used only on RC4710
and RCM4710 models. A yellow handled hose is for left
wing fold used only on RCL4710 and RCML4710 models.
When set up for dual-action fold, the handles have
directional arrows to identify what the hose does when
charged. See
.
WARNING
!
To prevent serious injury or death:
Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. 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 leaks. A doctor familiar with this type of
injury must treat the injury within a few hours or gangrene
IMPORTANT:
Before moving the cutter, relocate
park jack to the storage base located on the left wing
or weight box. Make sure jack is stored with its base
level or lower than the head to prevent water and
Hydraulic Hook-up (LP Performance Hitch Shown)
Figure 1-13
Refer to Figure 1-13:
1. Route hydraulic hoses (#7) through hose support
loop (#14) and attach couplers to the tractor remote
outlets. If tractor has a float option on one of the
outlets, connect wing lift hose to that outlet and set
tractor control lever for that outlet in float position
before cutting.
2. Apply spiraled hose wrap (#12) to hydraulic
hoses (#7) as needed to keep the hoses from pinch
areas caused by raising and lowering the deck,
folding the wing up and down, and while making
turns with the tractor.
