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 Positioning
Figure 3-4
Unfold Wing and Set Deck Cutting Height
Refer to Figure 3-4:
1. Inspect blade carriers for locked blades prior to
lowering the wing. Separate locked blades.
2. Start tractor and raise wing up to release any tension
on the transport lock bar (#3).
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.
Cutting Blades
Blade Carrier
33869
IMPORTANT:
Cutting blades may become locked
together (overlapped) when the wing is raised for
transport. Operating cutter in this condition will result
in severe deck vibration. Inspect wing for locked
blades prior to power-on operation.
3. Without lowering the cutter, shut tractor down before
Refer to Figure 3-3 on page 36:
4. Remove hairpin cotter (#1) and transport lock bar
from cylinder pin (#4).
Refer to Figure 3-2 on page 36:
5. Rotate end of transport lock bar (#3) up to storage
tab (#2). Secure transport lock bar with hairpin
cotter (#1).
6. Start tractor and lower the wing down.
7. Adjust cutter to field cutting height. See instructions
for
Set Wing Folding 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 wheels
are in continuous contact with the ground at all times.
Rephasing Out Of Phase Lift Cylinders
The rephasing lift cylinders will not function properly if
they are out of phase. This will be noticeable when one
deck is higher or lower than the other deck. Retracting
one lift cylinder, more than the other, can cause this
situation.
Some tractors with pressure detents will not allow the
hydraulic systems to rephase automatically. To manually
rephase lift cylinders, raise cutter completely up and hold
the tractor hydraulic lever on a few more seconds to give
the cylinders time to rephase. Do this each time you raise
the cutter and when the decks are uneven.
Momentarily reversing the hydraulic lever immediately
after rephasing the lift cylinders 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 the 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.
IMPORTANT:
When cutting, the wing folding lever
should be in float position to avoid damage to the
