Tractor & Cutter Inspection
Make the following inspections with cutter attached to a
tractor and cutter parked on a level surface, PTO
disengaged, and cutter blades stopped.
1. Inspect tractor safety equipment to make sure it is in
good working condition.
2. Inspect cutter safety equipment to make sure it is
installed and in good working condition.
3. Check driveline to make certain it is securely
connected to the tractor PTO shaft and cutter
gearbox shaft. Also, make certain that the guards are
in good working condition and in place.
4. Check driveline hanger. Make sure it is rotated down
away from the driveline.
5. Remove 3-point lower arms or secure them in the
raised position so they do not interfere with driveline,
hoses, or hitch.
6. Check all hoses and wires to be sure that they will not
pinch or come in contact with rotating drivelines.
7. Start tractor and carefully raise and lower implement
to ensure tractor drawbar, tires, and other equipment
on the tractor do not contact cutter or PTO driveline.
See also “Driveline Clearance Check” on page 21
8. Raise center deck fully up.
9. Shut tractor down properly without lowering
implement. Refer to “Tractor Shutdown Procedure”
on page 14.
10. Place sturdy support blocks or jack stands under the
four center deck corners.
11. Start tractor and lower center deck down onto the
supports.
12. Shut tractor down properly before dismounting. Refer
to “Tractor Shutdown Procedure” on page 14.
13. 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 42.
14. Inspect hydraulic hoses for wear, damage, and
hydraulic leaks. See “Avoid High Pressure Fluids
Hazard” on page 3. Replace damaged and worn
hoses with genuine Land Pride parts.
15. Make repairs to cutter and tractor before continuing
with “Blade Operation Inspection” on this page.
Blade Operation Inspection
!
DANGER
Tractor PTO shield and gearbox shaft shields must be secured
in place when operating cutter to avoid injury or death from
entanglement in driveline.
!
WARNING
Always disengage PTO, place tractor in park or set park
brake, shut tractor engine off, remove switch key, and wait for
blades to stop before dismounting from tractor.
1. Make sure cutter blades are not locked against each
other. See “Field Set-up” on page 33.
2. Remove support blocks or jack stands and set
transport locks for field operations. See “Transport
Lock” on page 32
3. Lower cutter decks down until blades are about 2" off
the ground.
4. Start tractor and set throttle speed just above idle.
Use tractor’s PTO soft start option if available. Slowly
engage PTO to get blades rotating. (Also see
“Engage Blades” instructions on page 34.)
5. Initial start-up vibration is normal and should stop
after a few revolutions. Stop PTO rotation
immediately if vibration continues.
6. Once cutter is running smoothly, increase throttle to
full PTO speed. If cutter vibrates excessively for 3
seconds at full speed, immediately disengage PTO,
shut tractor down properly, and remove switch key.
7. Block center deck up before working under cutter.
8. Check blades for a locked-up situation. Unlock
blades if locked-up.
9. Check for other probable causes such as broken or
bent blades, loose blades, loose gearbox mounting
bolts, and bent driveline.
10. Taking proper precautions, make necessary repairs,
and adjustments.
11. Repeat steps 1 to 10 above to make certain vibration
problems are fixed before putting the cutter back into
service.
IMPORTANT: Read all “Safety Information”
starting on page 29 before operating the cutter.
IMPORTANT: Stop PTO immediately if vibration
continues after a few revolutions during start-up and
anytime vibration occurs thereafter.
IMPORTANT: Do not exceed cutter’s rated PTO
speed (540 or 1000 rpm). Excessive PTO speed will
cause damage to the power train components.
