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
Refer to Figure 1-18:
1. Route wing folding cylinder hose (#6) through hose
support loops and connect to a remote outlet with
float option if available.
2. Route rephasing lift cylinder hoses (#7) through hose
support loops and connect to a tractor duplex outlet.
3. Secure hydraulic hoses together with zip ties (#13)
as needed to keep them from pinch areas caused by
raising and lowering the deck, folding the wing, and
making turns with the tractor.

Rephasing Lift Cylinders & Plumbing
Refer to Figure 1-18:
The deck cutting height and transporting height are
controlled by two rephasing cylinders (#1 & #2) which are
plumbed together to operate in unison. The decks will not
lift properly if rephasing cylinders are plumbed
incorrectly. Use Figure 1-18 to verify plumbing.
