operators of other vehicles. Comply with
all Federal, State, and local laws.
CAUTION
TRANSPORTING
MOWING INSTRUCTIONS
OPERATING INSTRUCTIONS
NOTE: Always disengage PTO before raising mower to
transport position.
Before beginning to mow, the following inspection should
be performed:
1.When raising the mower to transport position, be sure
that driveline does not contact tractor or mower. Adjust
and set the tractor's 3-point hitch lift height so that the
driveline does not contact mower deck in the fully
raised position.
2.Be sure to reduce tractor ground speed when turning,
leaving enough clearance so that the mower does not
contact buildings, trees, or fences.
3.Select a safe ground travel speed when transporting
from one area to another. When traveling on roadways,
transport in such a way that faster moving vehicles may
pass safely.
4.When traveling over rough or hilly terrain, shift tractor to
a lower gear.
1.Check oil level in gearbox.
2.Check that all plugs in gearbox have been replaced and
tightened properly.
3.Be sure all mower knives, bolts and nuts are tight.
4.Be certain all guards and shields are in place and
secure.
5.Grease driveline shaft and all other grease fittings.
6.Clear area to be mowed of rocks, branches and other
foreign objects.
7.Lower mower to ground. Set tractor throttle at approxi-
mately 1/4 open. Engage PTO to start blades rotating.
8.Operate with 540 rpm PTO tractor.
9.At first begin mowing at a slow forward speed and shift
up until the desired speed is achieved - maintaining 540
PTO rpm.
10.Mower knives will cut better at a faster blade speed
than at reduced throttle.
11.After mowing the first 50 feet, stop and check to see
that the mower is adjusted properly.
12.Do not make sharp turns or attempt to back up while
mower is on the ground.
13.Do not engage PTO with mower in the fully raised
position. Do not engage PTO at full throttle.
1.Clear area to be mowed of objects and debris that might
be picked up and thrown by the mower blades.
2.Grass is best cut when it is dry. Mowing wet grass can
cause plugging resulting in grass clumps behind the
mower.
3.Grass should be mowed frequently as shorter clippings
deteriorate faster.
4.If mowing extremely tall grass, it is best to raise
cutting height and mow the area, then lower cutting
height and mow a second time at the desired height.
Proper servicing and adjustments are the key to the long
life of any machine. With careful and systematic inspec-
tion of the mower, costly maintenance, time and repair
can be avoided.
THE GEARBOX AND TRANSMISSION ARE SHIPPED WITH-
OUT OIL.
ADD OIL BEFORE FIRST USE!

CAUTION
LEVELING THE MOWER
NOTE: Tractor and mower should be on level ground.
Leveling can be adjusted at the tractor's 3-point arms and
center link.
CUTTING HEIGHT ADJUSTMENT
3-POINT HITCH ADJUSTMENTS
The machines cutting height depends upon the position of
the rear roller.
1.Remove the bolts that fix the roller on both sides.
2.Lift or lower both sides of roller in equal measurements.
3.Replace bolts and re-tighten.
1.Tension on the belt can be adjusted with the belt
tension bolt. Turn the bolt until desired tension is
achieved. When the belt has the correct tension the
gearbox should be adjusted so that the gearbox exten-
sion is running straight (parallel) with the flail mower.
Loosen bolts at the bottom of the gearbox and move
gearbox until gearbox extension is running straight.
2.Excessive tension on the belt may lead to premature
failure of belt and drive components.
The 3-point hitch system on this mower has been
designed for front to back flotation when mowing on
uneven terrain. Adjust tractor's top center link to place
the upper hitch pin vertically above or slightly behind the
lower hitch pins. The mower should be run with the back
15 degrees lower than the front.The hitch can also be
adjusted from side to side by turning the adjustment
handle. Turn handle until you have achieved your desired
location.
The Belt tension should be checked after the first 20
hours of use. And then every 40 hours of use.
