9. Place solid, non-concrete support blocks or jack
stands under the four center deck corners.
10. Start tractor and lower center deck down onto
supports.
11. Shut tractor down properly before dismounting.
12. With cutter resting on solid, non-concrete 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 47.
13. Inspect hydraulic hoses for wear, damage, and
hydraulic leaks. Before checking for leaks, read
“Avoid High Pressure Fluids Hazard” on page 3.
Replace damaged and worn hoses with genuine
Land Pride parts.
14. Make repairs to cutter and tractor before continuing
with “Blade Operation Inspection” on this page.
Constant Velocity (CV) Driveline
Figure 3-1
Avoid Extreme Turning Angles
Refer to Figure 3-1:
Plan your field cutting to minimize number of turns,
especially extreme turning angles. Avoid tractor-to-cutter
turning angles that exceed driveline maximum turning
angle. If the turn cannot be avoided, disengage tractor
power take-off and wait for driveline to stop before
making the turn.

Constant Velocity Driveline:
Maximum turning angle = 80

DANGER
!
To prevent 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:
•
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
•
Stop power take-off immediately if vibration continues after
a few revolutions during start-up and anytime vibration
occurs thereafter.
•
Some tractors are equipped with two power take-off speeds.
Be certain your tractor’s power take-off is set-up to operate
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.
1. Make sure cutter blades are not locked against each
other. See
“Field Set-up”
on page 36.
2. Remove deck supports and set transport locks for
field operations. See
“Transport Pins”
on page 34 .
3. Lower cutter decks 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”
instructions on page 37.)
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, and shut tractor down
properly before dismounting according to
“Tractor
Shutdown Procedure” on page 15.
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 above to make certain vibration is
corrected before putting cutter back into service.
Transport Pins
IMPORTANT:
Read all
“Safety Information”
starting on page 32 before operating the cutter.
IMPORTANT: Always disengage tractor’s power
take-off and wait for blades to come to a complete
stop before raising the wings to transport position.
Wing drivelines, wing gearboxes, and splitter
gearbox can be damaged if driveline is turning.
