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, one on the wing for lifting the cutter and one
for folding the wing. 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 1-17:
•
The black handled hose is connected to the lift cylinder.
•
The red handled hose is connected to the right wing
folding cylinder on models RCB5710 and RCBM5710.
•
The yellow handled hose is connected to the left wing
folding cylinder on models RCBL5710 & RCBML5710.
•
When setup for dual-action, the handles have
directional arrows to identify which hose extends the
cylinder and which hose retracts the cylinder.

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 1-18:
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 deck, folding and unfolding
the wing, and while making turns with the tractor.
