6.1 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.
4. Level the mower deck front to rear by
adjusting the leveling rods linking the
tongue to the rear axle. DO NOT allow feet
or other body part underneath the mower
when making adjustments. To adjust rod
length, loosen jamnut and screw
turnbuckles. To lower the front, lengthen
the rods and to raise the front, shorten the
rods. DO NOT unscrew turnbuckles to the
point that either rod threaded ends
becomes disconnected which will cause
the mower to fall. Re-tighten jamnuts when
deck is leveled.
5. IMPORTANT: Alternate adjustments
between rods and adjust at equal lengths to
maintain equal tension. Improper
adjustments may cause rods to snap or
bend.
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.
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.
