Transporting
WARNING
!
To avoid serious injury or death:
•
When traveling on roadways, travel in such a way that
other vehicles may pass you safely. Use LED lights, clean
reflectors, and a slow moving vehicle sign that is visible
from the back to warn operators in other vehicles of your
presence. Always comply with all federal, state, and local
•
Always disengage power take-off and wait for driveline to
stop rotating before raising implement to transport position.
1. Make sure driveline does not contact tractor or cutter
when raising cutter to transport position.
2. Reduce tractor ground speed when turning and leave
enough clearance so cutter does not contact
obstacles such as buildings, trees, or fences.
3. Limit transport speed to 20 mph. Transport only with
a farm tractor of sufficient size and horsepower.
4. When traveling on roadways, transport in such a way
that faster moving vehicles may pass you safely.
5. Shift tractor to a lower gear when traveling over rough
or hilly terrain.
Blade Engagement & Disengagement
Cutter blades can lock-up against each other during
start-up and shut-down especially if the tractor’s power
take-off engagement is
“INSTANT ON”
and
“INSTANT
OFF”
. Following Blade Engagement and Blade
Disengagement instructions below will help eliminate
blade lock up.
Blade Engagement
1. Increase throttle to a speed just enough to get the
cutter started without stalling tractor while slowly
engaging drivelines. Use tractor’s power take-off soft
start option if available.
2. Ensure that all power shafts are rotating and that the
cutter is not vibrating excessively after ramping up to
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 down tractor, and remove switch
key.
3. Check blades for a lock-up situation. Block cutter
deck up before working under the unit. Unlock
blades, remove support blocks, and repeat
Blade Disengagement
1. Slowly decrease throttle speed until engine idle
speed is reached and then disengage power take-off.
2. Engage tractor park brake, shut tractor engine off
and remove switch key. Stay on tractor until blades
have come to a complete stop.
Field Operation
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.
1. Thoroughly inspect area to be cut for debris and
unforeseen objects. Mark any potential hazards.
instructions on this
page to start cutter blades turning.
3. Optimum ground speed depends on density of
material being cut, horsepower rating of tractor, and
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 tractor
down, usually between 2 to 5 mph.
4. Stop traveling and disengage power take-off after the
first 50 feet of cutting. Check cutter levelness and
cutting height to make certain it is adjusted properly.
5. Do not engage power take-off with 3-point cutter fully
raised.
6. Periodically disengage power take-off, shut down
tractor, remove key, and check for foreign objects
wrapped around the blade spindle. Block cutter deck
up before removing objects.
7.
Frequently inspect cutter for loose bolts and nuts.
Tighten all loose bolts and nuts as indicated in the
“Torque Values Chart”
on page 36.
8. For additional information, see
Maintain correct power take-off speed.
Loss of power take-off speed will allow blades to
swing back resulting in ragged, uneven cutting.
IMPORTANT:
Your cutter is equipped with free
swinging cutting blades to reduce shock loads when
striking obstacles. However, it is best to avoid striking
obstacles to extend cutter and blade life.
NOTE:
Do not cut in wet conditions. Wet material
will build up on the deck underside creating poor
discharge, high wear, and additional horsepower.
NOTE:
Periodically disengage power take-off, turn
off tractor, remove key & check for objects wrapped
around blade spindle. Block deck up before
removing objects.
Frequently inspect cutter for loose bolts and nuts.
Tighten all loose hardware as indicated in the
“Torque Values Chart”
on page 36.
