Field Set-up
DANGER
!
To avoid serious injury or death:
Clear area to be cut of debris and other unforeseen removable
objects before cutting. Mark non-removable hazards such as
tree stumps, post stubs, protruding objects, rocks, drop-offs,
holes, etc. with a visible flag.
WARNING
!
To avoid serious injury or death:
The following operational procedures should be carried out
by the tractor operator. Other persons should not be in the
area. All cutter operations including field set-up should be
stopped when other persons are in the vicinity.
Field Inspection
Thoroughly inspect area to be cut for debris and
unforeseen objects. Remove all potential hazards and
mark any that cannot be removed.
Wing Deck Blade Position
Figure 3-5
Unfold Wings and Set Deck Cutting Height
1.
Inspect blade carriers for locked blades prior to
lowering the wings. Separate locked blades.
2. Start tractor and raise both wings up to release any
tension on the transport lock bars.
3. Without lowering the cutter, shut tractor down before
dismounting. Refer to
Refer to Figure 3-4 on page 34:
4. Remove hairpin cotters (#1) from both left and right
wing cylinder pins (#4).
IMPORTANT:
Cutting should
not be
done in wet
conditions. Wet material will build up on the deck
underside creating need for additional horsepower,
high wear, and poor discharge.

Refer to Figure 3-3 on page 34:
5. Rotate end of transport lock bar (#3) up to storage
lug (#2) as shown. Secure with hairpin cotters (#1).
6. Start tractor and lower both wings down.
7.
Adjust cutter to field cutting height. See
on page 30 for detailed instructions.
Set Wing Lift Lever to Float Position
Use float position of your tractor’s hydraulic system to
provide automatic floating of wings for varying terrain
conditions. This will ensure wing gauge wheels are in
continuous contact with the ground at all times.
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 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
above for 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. Use
tractor’s power take-off soft start option if available.
3. Ensure 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 tractor down, and remove switch key. Wait for
blades to stop rotating before dismounting tractor.
4. Investigate cause if cutter was shut down due to
excessive vibration. See
on page 33 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.
