6. Raise or lower park jack (#3) to align hitch (#10) with
bolt hole in swivel clevis (#9).
7.
Restart tractor and back up to cutter hitch until hitch
bushing (#10) aligns with holes in swivel clevis (#9).
8. Shut tractor down before dismounting according to
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.
10. Lower park jack (#3) until hitch weight is supported
by the drawbar.
11. Remove detent pin (#8) and relocate park jack (#3)
from the hitch mount to the storage mount on the left
side of the cutter. Secure jack with its detent pin.
Make sure the jack base is level with, or lower than
the jack crank head. See cover picture for the correct
mounting positioning.
12. Attach hitch safety chain (#4) to the tractor. Adjust
chain length to remove all slack except what is
necessary to permit turning. Lock chain hook
securely 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 (two-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.
Refer to Figure 1-15:
•
The black handled hose is connected to the lift cylinder.
•
The red handled hose is connected to the right wing
folding cylinder on models RC5710 and RCM5710.
•
The yellow handled hose is connected to the left wing
folding cylinder on models RCL5710 & RCML5710.
•
When setup for dual-action, the handles have
directional arrows to identify which hose extends the
cylinder and which hose retracts the cylinder.
IMPORTANT:
Before moving the cutter, relocate the
park jack to its storage mount on the cutter. Make
sure the jack is stored with its base level or lower
than the head to prevent water and freeze damage.

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
Refer to Figure 1-14:
1. Route hydraulic hoses (#1) through hose support
loop (#2) 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 (#3) to hydraulic hoses (#1)
as needed to keep hoses from becoming pinch while
raising and lowering the decks, folding and unfolding
the wing, and while making turns with the tractor.
