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 cutter is raised and lowered.
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.

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.
4. Level the cutter 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 cutter when making adjustments.
to adjust rod length, loosen jamnut and screw ratchets. to lower the front, lengthen the rods
and to raise the front, shorten the rods.
DO nOt unscrew ratchets to the point that either rod threaded ends becomes disconnected
which will cause cutter to fail. Re-tighten jamnuts when deck is leveled.
ImPORtant: alternate adjustments between rods and
adjust at equal lengths to maintain equal tension. Improper
adjustments may cause rods to snap or bend.
5. Place split collar assemblies on the center axle hydraulic cylinder rod to maintain a set cutting
height each time the cutter is raised and lowered.
If wing(s) are not level (parallel to center section), back jamnut off and adjust ratchet shorter to
raise the wing outside edge and longer to lower the wing outside edge. It may be necessary to use
wing lift cylinder to relieve pressure from the linkage retaining pin.
tighten jamnut when complete.
to avoid serious injury or death: operating cutter with rear lowered excessively will result in an
uneven cut and could cause rapid blade, skid and driveline wear and possibly cause structural
failures in the wing hinge area.
