10. Start tractor and raise cutter up enough to remove
solid supports from under the deck.
11. Lower cutter down to a height 2 to 3 inches off the
ground.
12. Set throttle to idle or slightly above idle, and slowly
engage PTO. Initial start-up vibration is normal and
should stop after a few revolutions. Stop PTO rotation
immediately if vibration continues.
13. Once cutter is running smoothly, slowly increase
tractor PTO speed to 540 RPM. Stop PTO rotation
immediately if vibration occurs.
14. Investigate cause of vibration and make repairs
before putting cutter back into service.
Transporting
!
WARNING
When traveling on public roads, use accessory lights, SMV
sign, clean reflectors, and other adequate devices to warn
operators in other vehicles of your presence. Always comply
with all federal, state, and local laws.
!
WARNING
Reduce ground speed when turning and leave enough
clearance to avoid making contact with obstacles such as
buildings, trees, and fences. Making contact can result in
equipment damage and serious injury or death.
!
WARNING
Do not tow cutter above 20 mph. Doing so can result in loss of
tire, tire blow-out, and/or loss of control resulting in
equipment damage and serious injury or death.
1. Make sure driveline does not contact tractor or cutter
when raising cutter to the transport position.
2. Reduce tractor ground speed when turning and leave
enough turning 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.
IMPORTANT: Do not exceed rated cutter PTO
speed. Excessive engine speed will cause damage
to power train components.
IMPORTANT: Always disengage tractor PTO before
raising cutter to transport position.
Blade Engagement & Disengagement
Cutter blades can lock-up against each other during
start-up and shut-down especially if the tractor’s PTO
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 speed just enough to get the blades
rotating without stalling tractor while slowly engaging
PTO. Use tractor’s PTO 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
PTO speed for at least 3 seconds. If excessive
vibration continues after 3 seconds at full PTO
speed, disengage PTO immediately, shut down
tractor, remove switch key, and wait for blades to
come to a complete stop.
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
Engagement” instructions.
Blade Disengagement
1. Slowly decrease throttle speed until engine idle
speed is reached and then disengage PTO.
2. Engage tractor park brake, shut tractor engine off
and remove switch key. Stay on tractor until blades
have come to a complete stop.
