9. Place sturdy, non-concrete support blocks or jack
stands under the four center deck corners.
10. Start tractor and lower center deck down onto the
supports.
11. Shut tractor down properly before dismounting. Refer
to “Tractor Shutdown Procedure” on page 14.
12. 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 43.
13. 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.
14. Make repairs to cutter and tractor before continuing
with “Blade Operation Inspection” on page 33.

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 the driveline to stop rotating
before making the turn.

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.
1. Make sure cutter blades are not locked against each
other. See
“Field Set-up” on page 35.
2. Remove deck supports and set transport locks for
field operations. See “Transport Locks” on page 34.
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” instructions on page 36.)
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.
IMPORTANT: Read all “Safety Information”
starting on page 31 before operating the cutter.
