•
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
Conventional U-Joint Driveline
Figure 3-1
Constant Velocity (CV) Driveline
Figure 3-2
Avoid Extreme Turning Angles
Refer to Figure 3-1 & Figure 3-2:
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 the driveline to stop rotating
before making the turn.
•
Standard Conventional Driveline:
Maximum turning angle = 35
o
.
•
Constant Velocity Driveline:
Maximum turning angle = 80

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

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
•
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting
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
2. Remove deck supports and set transport locks for
field operations. See
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
instructions 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.
IMPORTANT:
Read all
starting on page 31 before operating the cutter.
