1. Make sure the tractor is equipped with the
correct PTO shaft and the drawbar is extended
14" from the end of the PTO shaft to the hitch
point.
2. Block the mower wheels in place and use the
attached parking jack to raise or lower the
tongue clevis to the height of the tractor
drawbar. Note: Always place jack foot on firm
surface or place board under jack for support.
3. Board the tractor and start the engine. Back the
tractor to the mower aligning the drawbar hitch
hole with the mower hitch clevis. Turn off the
tractor engine, set the parking brake, place the
tractor in park, and dismount.
4. To attach the mower, place two 1" flatwashers
(1) positioned under top lip of tongue clevis and
to the top of drawbar.
flatwashers (2) between the bottom of drawbar
and bottom lip of clevis to fill open space. Insert
a 1" x 4-1/2" grade 5 or 8 bolt (3) through clevis
and drawbar and retain in position with a 1"
locknut (4). The bolt and locknut should be
tightened securely to support the tongue
properly without springing or breaking the clevis.
Never attach mower to the tractor with a pin not
having a nut.
5. Securely attach mower safety chain to tractor
drawbar or drawbar support frame.
6. Lower the jack until the tongue is completely
supported by the drawbar. Remove jack from
the tongue and place on storage bracket of
mower main frame.
7. If using a hydraulic cylinder, connect hydraulic
hose ends into tractor hydraulic ports.

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
