Pull Type Models
Cutting height is set by adjusting ratchet jack which rotates rear wheel bar. On units fitted with hydraulic
cylinder, height is set by adding split collar spacers around cylinder rod. Avoid any scalping or ground contact
which may result in knife breakage. Cutting height should be set to avoid any ground contact. For optimum
knife wear, raise knife tips above dust clous (approximately 3-4 inches above row). On larger units, the overall
level of rows should be considered to avoid ground contact over width of machine. Side plate should be
parallel to ground. Tongue assembly has two height positions. Pin in top holes for standard shredding of crops.
In tall crops such cotton, pin in lowes holes for additional crop clearance.
Lift Type Models
Adjustment of the wheel bar combined with the tractor lift arms maintain cutting height. The 3-Point Hitch is
fitted with a floating link to reduce any load transferred to top link. The tractor lift should be set to correct level
to maintain correct height at front of machine.
Machine should be held level by tractor lift while mowing. Link float may be locked out by reversing center lock
plate in link assembly. This lock plate should only be used in level conditions and on tractors which are unable
to maintain lift level.
Semi-Mount Models
The cutting height is maintained with a combination of tractor 3-Point Lift adjustment and wheel bar
adjustment. Individual caster adjustment is to level caster pivot pin angle perpendicular with the ground, for
proper operation. Tractor should be attached to lower hitch point only. Always use a quick hitch to attach to
mower otherwise driveline failure may result.
Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches.

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
