OPERATION
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.
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. Place split collar assemblies on the center
axle hydraulic cylinder rod to maintain a set
cutting height each time the mower is
raised and lowered.
LEVELING WING SECTIONS WITH CENTER
To level the wing sections with the deck center,
adjust the leveling screw between the wing axle
and the center axle. To lower the wing, loosen the
jamnut and shorten the screw assembly, lengthen
the screw assembly to raise the wing. After wings
are leveled, retighten jamnuts to maintain settings.
