WING LIFT/FOLD - OPTIONAL AXLE LEVEL LIFT CYL’S
15 FT - OPTIONAL HYD LEVEL LIFT AXLE - W/ STD WING LIFT / FOLD
Note: Hydraulic Axle Lift Option. This has three axle cylinders, one center and one each wing. These
cylinder are different bore size, the center is 3-1/2" bore, RH wing 3-1/4" bore and LH wing 3" bore. The
hydraulic hose's are routed to largest bore, medium bore and then to the smallest bore cylinder. The hose
routing must be this way to work properly. The system has cylinders that have bypass grooves in the top
end of the barrels to allow the hydraulic oil to pass from one cylinder to the other. The return hose is
connected to the return valves return hose, this is recommended connection as this puts the return hose
at hydraulic oil level and helps prevent air from accumulating in the cylinders during use. If optional Valve
is not used and cylinders are connected direct to tractor, the return hose should be connected below
hydraulic oil to keep hose full of oil. Tractor connections must have the detent positions.
