7.
Restart tractor and back tractor up to cutter hitch until
hole in 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 snugly to remove all
play.
Do Not
torque 1" locknut.
10. Lower park jack (#3) until hitch weight is supported
by the drawbar.
11. Remove park jack (#3) from hitch frame and attach it
to the left-hand wing storage base with detent
pin (#8). Make sure base is level with or lower than
the head especially after the wings are folded up. See
cover picture for correct positioning.
12. Attach hitch safety chain (#4) to tractor. Adjust chain
length to remove all slack except what is necessary
to permit turning. Securely lock chain hook to the
safety chain.
13. Continue with
Hydraulic Hook-up
The required number of duplex outlets at the tractor is
dependent upon how the cutter is set-up. The standard
cutter is equipped with three hydraulic cylinders with one
in the center for lifting the cutter and one on each wing for
folding the wings simultaneously. All three cylinders are
set-up for single-action (one-way) operation.
Each duplex outlet on your tractor can perform only one
operation. One outlet is needed for lifting the cutter and
one for lifting the wings simultaneously. It is highly
recommended to connect the wing fold hose to a duplex
with float capabilities and use the float when in field
operation.
The black handled hose is for the lift cylinder and the red
handled hose is for the fold cylinders.
WARNING
!
To avoid 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:
Protect park jack by storing it on the
Hydraulic Hook-up (LP Performance Hitch Shown)

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.
