OPERATION
Never stand or allow another person to stand between a running Tractor and the Mower
when attaching the Implement to the Tractor. Always shut the Tractor completely off before
attempting to connect the Mower pins to the Tractor hitch.
5.1 Connecting the Boom 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
boom mower.
3. Board the tractor and start the engine. Position
the tractor to the boom mower with the 3-point
lift arms positioned between the respective set
of A-frame lift lugs. NOTE: Set the 3-point lift
control to “Position Control” so that the lift arms
maintain a constant height when attaching the
boom mower. See the tractor Operator’s
Manual for correct settings when attaching 3-
point equipment.
4. Turn off the tractor engine and dismount.
5. One lift arm at a time, align arm end hole
between the set of A-frame lift lugs. Insert hitch
pin through the lug and arm holes and insert
retaining pin into hitch pin.
6. Walk around to opposite side and repeat
procedure for remaining lift arm and hitch pin.
7. Extend or retract 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.
8. 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.

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
