OPERATION
7.1 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.
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health.
(SG-23)
Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions.

6. CONNECTING THE MOWER TO THE TRACTOR
Use extreme caution when connecting the mower to the tractor. The mower should be securely resting on
front stands or tongue jack stand and rear gauge wheels. Keep hands and feet from under the mower ends
and clear of pinch points between the tractor hitch arms and mower pins. OPS-F- 0035
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.

7. 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
