Section 3: Operating Instructions
Tractor & Cutter Inspection
Make the following inspections with cutter attached to a
tractor and cutter parked on a level surface, power take-
off 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 power take-off 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 the folding wing and
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 driveline.
8. Raise center deck fully up.
9. Without lowering cutter, shut tractor down properly
before dismounting. Refer to "Tractor Shutdown
Procedure" on page 17.
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 17.
13. With cutter resting on solid supports, power take-off
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 Blades" on page 41.
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.
16. Continue with "Blade Operation Inspection" on this
page.

Blade Operation Inspection
!
DANGER
To avoid serious injury or death: Tractor power take-off shaft
shield, driveline shields, and gearbox shaft shields must be
installed and in good working condition to avoid driveline
entanglement and projectiles flying off of the driveline.
!
WARNING
To avoid serious injury or death:
•
Stop power take-off immediately if vibration continues after
a few revolutions during start-up and anytime vibration
occurs thereafter.
•
Always shut tractor down using "Tractor Shutdown
Procedure" provided in this manual before dismounting
tractor.
!
CAUTION
To avoid minor or moderate injury: Some tractors are
equipped with two power take-off speeds. Be certain your
tractor's power take-off is set at the implement's rated power
take-off speed or equipment breakage may result. RC models
are rated for 540 rpm and RCM models are rated for 1000
rpm.
IMPORTANT: Read all "Safety Information"
starting on page 30 before operating the cutter.
1.
Make sure cutter blades are not locked against each
other. See "Field Set-up" on page 34.
2. Remove deck supports and set transport locks for
field operations. See "Transport Locks" on page 33
3. Lower cutter until blades are about 2" off the ground.
4. Start tractor and set throttle speed just above idle. If
available, use tractor's power take-off soft start option.
Slowly engage power take-off to get blades rotating.
(See "Engage Blades" on page 35.)
5. Initial start-up vibration is normal and should stop
after a few revolutions. Stop power take-off rotation
immediately if vibration continues.
6. Once cutter is running smoothly, increase throttle to
full cutter speed (540 or 1000 rpm). If cutter vibrates
excessively for 3 seconds at full speed, immediately
disengage power take-off, shut tractor down, 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, bent driveline etc.
10. Take proper precautions to make necessary repairs
and adjustments.
11. Repeat steps 1-10 to make certain vibration is
corrected before putting cutter back into service.
