OPERATION
5.1 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 differently. Refer to the tractor
Operator’s Manual for connecting and
operating hydraulics for your particular
model tractor.
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 low-
ering the mower.
6. SETTING MOWER CUTTING HEIGHT
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower makes a
more uniform cut, distributes clippings more evenly, increases tractor efficiency, and follows the contour of
uneven terrain. Note: Avoid very low cutting heights, striking the ground with the blades gives the most
damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may
cause objects to be thrown out from under the mower deck.
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death.
