Hydraulic line Support
after connecting the cutter 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 braces to
lower the cutter 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 braces. neVeR drive out bar pins and
neVeR remove braces that have tension on them.
SEtting tHE cutter
Properly setting the cutting height is essential for efficient and safe operation. a properly set cutter
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 cutter and drive.
Blades contacting the ground may cause objects to be thrown out from under the cutter deck.
always avoid operating the cutter at a height which causes the blades to contact the ground.
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. (SG-14)
Setting deck Height
lEVEling dEcK cEntER SEction
1. Place the tractor and cutter on a level surface and
lower both wings.
2. using the center section hydraulic cylinder, position
the cutter so the skid shoes are 1” less off the ground
than the desired final cut height. For example, for a
3” cut raise or lower the cutter until the skid shoes
are approximately 2” off the ground.
3. Shut down the tractor, place the transmission in
park, and set the parking brake before dismounting.

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 braces 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 braces. NEVER drive out bar pins and NEVER remove braces that have tension on
them.
7.1 Setting Deck Height
LEVELING DECK CENTER SECTION
1.
Place the tractor and mower on a level
surface and lower both wings.
2. Using the center section hydraulic cylinder,
position the mower so the skid shoes are 1”
less off the ground than the desired final cut
height. For example, for a 3” cut raise or
lower the mower until the skid shoes are
approximately 2” off the ground.
3. Shut down the tractor, place the
transmission in park, and set the parking
brake before dismounting.
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 serious
injury or even death.
