Hydraulic Line Support
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 Cylinder Priming
Hydraulic Cylinders must be filled with hydraulic oil before removing the wing transport lock pins to lower the
mower wings. 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 a second time. Ensure wings are entirely supported by the cylinders before
removing the transport lock pins. NEVER drive out bar pins and NEVER remove bars that have tension on
them.
7. 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. OPS-U- 0010
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 death
or serious injury.
