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
left-hand wing storage base with detent pin (#8).
Ensure jack base is level with, or lower than the jack
crank head, especially after the wings are folded up.
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 three hydraulic cylinders with one
in the center for lifting the cutter and one on each wing for
folding the wings simultaneously. The center lift cylinder
is set up for single-action (one way) operation. The wings
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 wings simultaneously. Two outlets are
needed to fold the wings independently. It is highly
recommended to connect the wing fold hose(s) to a
duplex outlet with float capabilities and use the float
when in field operation.
The black handled hose is for the lift cylinder. The red
handled hose is for simultaneous fold or right hand wing
fold when setup independently. The yellow handled hose
is for left hand wing fold when set up independently.
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 by storing it on the left wing deck. Make
sure the jack is stored with its base level or lower
than the head to prevent water and freeze damage.
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.
