6. SETTING THE MOWER
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a
more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow 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. Always avoid operating the mower at a height which causes the blades to
contact the ground.
5.2 Connecting Mower Hydraulic Lines to the Tractor
With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the
control levers back and forth several times or placing the levers in the float position. Keep mower hydraulic lines,
hoses, quick couplers, and swivels free of contamination. Never leave a disconnected hose end open and cap the
tractor hydraulic outlet ports when not in use. If the tractor ports or mower hydraulic hose ends become contaminated,
wipe clean with a rag before connecting.
After connecting the mower hydraulic lines to the tractor, support the hoses with the equipped brackets. Ensure
that hoses do not contact the driveline, do not bind while turning, and do not become pinched or kinked.
Hydraulic Line Support
Hydraulic Cylinders must be filled with hydraulic oil before removing the wing transport pins to lower the mower
wings and deck. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position
until the cylinders fully retract (wing cylinders) and extend (center cylinder). Place control levers in the float
position and repeat process several more times to purge all air from the system. Ensure wings are entirely
supported by the cylinders before removing the transport pins. NEVER drive out pins and NEVER remove
transport pins that have tension on them.
Hydraulic Cylinder Priming
Never work under the Implement, the framework, or any lifted compo-
nent unless the Implement is securely supported or blocked up to
prevent sudden or inadvertent falling which could cause serious injury
or even death.
