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 the
supports.
11. Shut tractor down properly before dismounting.
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
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
Constant Velocity (CV) Driveline
Figure 3-1
Avoid Extreme Turning Angles
Plan your field cutting to minimize number of turns,
especially extreme turning angles. Avoid tractor-to-cutter
turning angles that exceeds 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

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:
•
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting
•
Stop power take-off immediately if vibration continues after
a few revolutions during start-up and anytime vibration
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
1.
Make sure cutter blades are not locked against each
other. See
2. Remove deck supports and set transport locks for
field operations. See
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
instructions on page 33.)
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 above to make certain vibration is
corrected before putting cutter back into service.
