Unfold Wings
Refer to Figure 3-4:
DANGER
!
To avoid serious injury or death:
Keep everyone away from the cutter when folding or unfolding
the wings or when raising or lowering the cutter. The cutter
can pinch or crush a person when performing these
1. Inspect blade carriers for locked blades prior to
lowering the wings. Separate locked blades.
Wing Deck Blade Positioning
Figure 3-4
Refer to Figure 3-3 on page 30:
2. Start tractor and raise both wings up to release any
tension on transport locks (#3).
3. Without lowering cutter, shut tractor down properly
4. Remove hairpin cotters (#1) from both left and right
wing cylinder pins (#4).
Refer to Figure 3-2 on page 30:
5. Rotate end of transport locks (#3) up to storage
lugs (#2). Secure with hairpin cotters (#1).
6. Start tractor and lower both wings down.
Set Blade Cutting Height
Adjust cutter to field cutting height. See
on page 26 for detailed instructions.
Place Wing Folding Lever In Float Position
Use the float position of your tractor’s hydraulic system to
provide automatic floating of the wings for varying terrain
conditions. This will ensure that the wing gauge wheels
are in continuous contact with the ground at all times.

Cutting Blades
Blade Carrier
The wing folding levers should be in
float position to avoid damage to the wing hydraulic
cylinders and axles while cutting on uneven terrain.
Do not let the wings flex down more
than 20 degrees while operating the cutter. Doing so
can cause damage to the cutter.
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.
Engage Blades
1. Select a gear range that will allow the cutter to make
a smooth cut without lugging the tractor down.
See
on page 32 for detailed
instructions.
2. With wings lowered, increase throttle to a speed just
enough to get the cutter started without stalling
tractor while slowly engaging power take-off
drivelines. Use tractor’s power take-off soft start
option if available.
3. Ensure all drivelines are rotating and that the cutter is
not vibrating excessively after ramping up to 540
power take-off speed for at least 3 seconds. If
excessive vibration continues after 3 seconds at full
540 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
on page 29 for detailed instructions.
5. If cutter was not shut down, commence forward
cutting operation at full power take-off operating
speed. Make a new gear selection if tractor is lugging
down or if cutter is making a rough cut.
6. Frequently inspect cutter for loose bolts and nuts.
Tighten all loose hardware as indicated in the
“Torque Values Chart”
on page 54.
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.
Cutter blades can lock-up against
each other during start-up and shut-down,
especially if tractor’s power take-off engagement is
“INSTANT ON” and/or “INSTANT OFF”. Follow Blade
