Set Wing Lift Lever In Float Position
Use the float position of your tractor’s hydraulic system to
provide automatic floating of the wing for varying terrain
conditions. This will ensure that the wing gauge wheel is
in continuous contact with the ground at all times.
Rephasing Lift Cylinders
The lift cylinders may, after a period of time, get out of
time or phase. The effects of this can be seen when one
deck of the cutter is higher or lower than the other
because its lift cylinder is retracted more than the other lift
cylinder. Also, tractors with pressure detentes do not
allow hydraulic systems to “automatically” rephase at the
top of the lift cycle. This must be done manually or the
rephasing cylinders will not function properly.
To rephase lift cylinders manually, raise cutter completely
up and hold tractor hydraulic lever on for several seconds
more to give cylinders time to rephase. This should be
done each time the cutter is raised and whenever the
decks are uneven.
Momentarily reversing the hydraulic lever immediately
after rephasing allows the cylinders to retract about 1/2"
and will help maintain a level cutter during transport.
Select Gear Range
Optimum ground speed depends on density of material
being cut, horsepower rating of tractor, and (in some
cases) terrain. Always operate tractor at cutter’s
full-rated power take-off speed in a gear range that allows
the cutter to make a smooth cut without lugging the
tractor down, usually between 2 to 5 mph. Loss of power
take-off speed will allow the blades to hinge back and
result in ragged, uneven cutting.

When operating, the wing folding lever
Engage Blades
1.
Select a gear range that will allow cutter to make a
smooth cut without lugging the tractor down. See
above for instructions.
2. With wing lowered, increase throttle to a speed just
enough to get the cutter started without stalling
tractor while slowly engaging power take-off. Use
tractor’s power take-off soft start option if available.
3. Ensure all power shafts are rotating and cutter is not
vibrating excessively after ramping up to full power
take-off speed for at least 3 seconds. If excessive
vibration continues after 3 seconds at full power take-
off speed, disengage power take-off immediately,
shut down tractor, and remove switch key. Wait for
blades to come to a complete stop before
dismounting tractor.
4. Investigate the cause if cutter was shut down due to
excessive vibration. See
on page 35 for detailed instructions.
5. Periodically, shut tractor down properly and dismount
to do an inspection. Refer to
on page 17 for proper shut down
procedure.
6. Periodically, shut tractor down properly and dismount
to do an inspection. Refer to
on page 17 for proper shut down
procedure.
7.
Dismount tractor and check for objects wrapped
around blade spindles. Block deck up before
removing objects.
8. Frequently inspect cutter for loose bolts and nuts.
Tighten all loose hardware as indicated in the
“Torque Values Chart”
Disengage Blades
1.
Slowly decrease throttle speed until engine idle
speed is reached.
2. Disengage power take-off.
3. Stay on the tractor until the blades have come to a
complete stop. Always place tractor in park or set
park brake, shut tractor engine off, and remove
switch key before dismounting.
