Road Side Cutting
When cutting road sides, Great Plains recommends the
Rotary Cutter be equipped with chain guards to stop
flying objects. Refer to
Used the flashing lights on the cutter to make yourself
more visible when cutting road sides.
Field Set-up
This cutter was designed for cutting grass, weeds, and
light brush. Cutting should
not be
done in wet conditions.
Wet material will build up on the deck underside creating
the need for additional horsepower, high blade wear, and
poor discharge.
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.
Wing Deck Blade Positioning
Figure 3-4
IMPORTANT:
Cutting blades may become locked
together (overlapped) when the wings are raised for
transport. Operating cutter in this condition will result
in severe deck vibration. Inspect wings for locked
blades prior to power-on operation.

Field Inspections
Thoroughly inspect area to be cut for debris and
unforeseen objects. Remove all potential hazards and
mark any hazards that cannot be removed with a flag.
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.
Refer to Figure 3-3 on page 27:
2. Start tractor and raise both wings up to release any
tension on the transport lock pins.
3. Without lowering cutter, shut tractor down properly
4. Remove hairpins (#1) and transport locks (#3) from
cylinder pins (#4).
Refer to Figure 3-2 on page 27:
5. For storage, rotate transport locks (#3) up and catch
on brackets (#2). Secure transport locks to brackets
(#2) with hairpins (#1).
6. Start tractor and lower both wing sections down.
Set Blade Cutting Height
Adjust cutter to field cutting height. See
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 may become locked
together (overlapped) when the wings are raised for
transport. Operating cutter in this condition will result
in severe deck vibration. Inspect wings for locked
blades prior to power-on operation.
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
