WARNING
Do not use a PTO adapter. A PTO adapter will increase strain
on the tractor’s PTO shaft resulting in possible damage to
shaft and driveline. It will also defeat the purpose of the
tractor’s master shield and could cause bodily injury or death.
!
WARNING
Do not use deck as a working platform. The deck is not
properly designed or guarded for this use. Using deck as a
working platform could cause serious injury or death.
!
WARNING
Do not operate cutter with loose hardware. Loose hardware
can result in a breakdown causing bodily injury or death.
!
WARNING
Do not use cutter to lift or carry objects, to pull fence posts,
stumps or other objects, or to tow other equipment. Doing so
can damage the cutter, cause serious bodily injury or death.
!
CAUTION
Buildup of debris around moving parts is a fire hazard. Keep
drivelines & other rotating parts free from debris to avoid
serious injury and property damage.
!
CAUTION
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level to avoid serious
injury and property damage.
!
CAUTION
Do not exceed rated cutting capacity of your cutter. See
specifications & capacities for specified cutting capacity.
Exceeding ratted cutting capacities can damage drive
components, cutter blades, and deck components.
!
CAUTION
Do not over speed PTO or machine damage may result. This
cutter is designed to operate at 540 RPM rear PTO.
Inspection of Tractor & Cutter
Make the following inspections with cutter attached to a
tractor, PTO disengaged, and all moving components
completely stopped:
1. Park tractor and cutter on a level surface.
2. Disengage PTO, place gear selector in park, set park
brake, shut tractor off, and remove switch key. Make
sure cutter blades have come to a complete stop
before dismounting from tractor.
3. Inspect tractor safety equipment to make sure it is
installed and in good working condition.
4. Inspect cutter safety equipment to make sure it is
installed and in good working condition.
5. Check driveline to make certain it is securely
connected to the tractor PTO shaft and cutter
gearbox shaft.
6. Check driveline guards to make certain they are in
good condition and in place.
7. Carefully raise and lower implement to ensure that
the drawbar, tires, and other equipment on the tractor
do not contact cutter frame or driveline.
8. With cutter resting on solid supports, PTO
disengaged, and blade rotation completely stopped:
• Check for and remove foreign objects wrapped
around blade spindles.
• Check for nicked, bent, broken, and worn cutting
blades. Replace or sharpen blades as required.
Refer to “Cutter Blade Maintenance” on page 20.
9. Remove solid supports from under the deck.
10. Verify cutter is set at the correct height. See “Deck
Leveling & Height Adjustments” on page 14.
The remaining inspections are made by engaging the
PTO to check for vibrations.
!
WARNING
Stop PTO immediately if vibration continues after a few
revolutions during start-up and anytime thereafter. Wait for
PTO to come to a complete stop before dismounting from
tractor to check for probable causes. Make necessary repairs
and adjustments before continuing.
11. Start tractor, 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.
12. Once the cutter is running smoothly, increase tractor
PTO speed to 540 rpm. Stop PTO rotation
immediately if vibration occurs.
13. Investigate cause of vibration and make repairs
before putting cutter back into service.
IMPORTANT: Do not exceed rated cutter PTO
speed. Excessive engine speed will cause damage
to power train components.
