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,
raise to transport height and loosen level rod
jam nuts. Position the mower so the skid shoes
are 1” less off the ground than the 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 parts underneath the mower when making adjustments. To adjust rod length
turn the 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. Raise to transport height and 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
Wings should be adjusted before use if they are not level with center deck section. Lower cutter until skids on
center section are approximately 1-2 inches off ground. Remove wing transport lock pin(s) and place in pin
storage hole. Lower wing(s) to ground allowing weight to rest on wheel(s). If wing(s) are not level (parallel) to
center section, loosen jam nut and turn turnbuckle body to adjust. Adjust longer to raise the wing outside edge
and shorter to lower the wing outside edge. It may be necessary to use wing lift cylinder to relieve pressure
from the linkage retaining pin. Tighten jam nut.
