OPERATION
6.2 Connecting Mower Hydraulics
1.With the tractor shut down and secured in position, move the hydraulic remote valve lever back and forth several times or place the hydraulic lever in the float position to relieve all hydraulic pressure. When connecting the mower hydraulic lines to the tractor, keep the hose, quick couplers, and swivels free of dirt and other contaminants. Wipe all dirt and other contaminants from the tractor hydraulic remote ports and mower hydraulic hose coupler with a clean rag before connecting.
2.Connect mower hydraulic hose to the tractor
remote port. Ensure the coupler locks in place making a good connection. Different tractor models receive hydraulic lines dif- ferently. Refer to the tractor Operator’s Man- ual for connecting and operating hydraulics for your particular model tractor.
Some tractor models allow the remote hydraulic valve to be configured for single acting cylinders. Refer to tractor operators manual and follow the appropriate instruc-
tions for single acting cylinder | operation. |
3.Ensure hydraulic hoses will not contact or become entangled with mower drivelines, do not bind when turning, or become pinched or kinked when operating, raising, and lowering the mower.
Hydraulic Cylinder Priming
Hydraulic Cylinders must be filled with hydraulic oil before releasing the wing transport locks to lower the mower. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position until the cylinders fully extend then place the control lever in the float position. Repeat the process several more times to ensure wings are entirely supported by the hydraulic cylinders before releasing the transport locks and lowering the mower.
