OPERATION
6.1 Connecting the Mower
1. Make sure the tractor is equipped with the
correct PTO shaft. Change shafts if needed.
2. Shorten or remove the tractor drawbar to avoid
interference when raising and lowering the
mower.
3. Board the tractor and start the engine. Position
the tractor to the mower with the 3-point lift arms
positioned at the same height and to the outside
of the mower hitch pins. Note: Set the 3-point lift
control to “Position Control” so that the lift arms
maintain a constant height when attaching the
mower. See the tractor Operator’s Manual for
correct settings when attaching 3-point
equipment.
4. Turn off the tractor engine, set the parking
brake, place the tractor in park, and dismount.
5. One lift arm at a time, position the tractor lift
arms over the A-frame hitch pins. Insert lynch
pins to retain lift arms to the mower. Walk
around to opposite side and repeat procedure
for remaining lift arm and hitch pin.
Note: Lower hitch link bar has two adjustment
positions. Bar can be extended 4” for additional tire
clearance.
6. Extend or retract the 3-point top link to align its
end hole with the holes of the mower’s top link.
Insert the top link hitch pin and insert retaining
pin into hitch pin.
7. Adjust any lower link check chains, guide
blocks, or sway blocks to prevent the mower
from swaying side to side and possible contact
with tractor rear tires.
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
