Road Side Cutting
When cutting road sides, Land Pride recommends the
Rotary Cutter be equipped with chain guards to stop
flying objects and Land Pride’s LED Light Kit to make your
self more visible. For additional information, refer to
Field Set-up
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
Inspect Field and Cutter Blades
1. Thoroughly inspect area to be cut for debris and
unforeseen objects. Remove all potential hazards
and mark any that cannot be removed.
Refer to Figure 3-4:
2. Inspect wing blade carrier (#1) and cutting
blades (#2) for locked blades prior to lowering the
wing. Use a pry bar or other tool to separate locked
blades.
IMPORTANT:
Cutting should
not be
done in wet
conditions. Wet material will build up on the deck
underside causing horsepower loss, high wear, and
poor discharge.
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.

Lower Wing Down & Set Cutting Height
Refer to Figure 3-3 on page 36:
1. Start tractor and raise wing up to release any tension
on the transport lock bar (#3).
2. Without lowering cutter, shut tractor down properly
before dismounting. Refer to
3. Remove hairpin cotter (#1) and transport lock bar
from cylinder pin (#4).
Refer to Figure 3-2 on page 36:
4. Attach transport lock bar (#3) to tab (#2) with hairpin
cotter (#1).
5. Start tractor and lower the wing down.
6. 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 lift cylinders may, over time, get out of phase. The
effects of this can be seen when the wing deck is higher
or lower than the center deck. this is because one lift
cylinder is retracted more than the other lift cylinder. Also,
tractors with pressure detents 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, raise cutter completely up and
hold tractor hydraulic lever on a few more seconds to give
lift cylinders time to rephase. Do this 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.
IMPORTANT:
When cutting, the wing folding lever
should be in float position to avoid damage to the
