WING LIFT & FOLD - STD AXLE LIFT CYLINDERS

Note: Standard Hydraulic Axle Lift. This has one axle cylinder on center axle only. This cylinder is 3" bore.
The hydraulic hose is routed to the base end of cylinder. The hose routing must be this way to work properly.
There is NO return hose connected to gland end of center axle cylinder, only a vent plug, this vent plug
allows cylinder to move freely without creating a vacuum inside cylinder barrel. If optional Valve is not used
and cylinders are connected direct to tractor, it is recommended tractor have at least three remotes. It is
also recommended these remotes have detent on them to allow wings to float or damage to deck could
occur. The wing axles are adjusted manually using the mechanical lift screws. This can be used on tractor
with only two remotes by connecting the wing cylinders together with a Tee fitting, but if doing this you will
lose the ability to decide which wing folds first (The wing with the least resistance will fold first).
