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 and cutter. Also, make
certain 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 wings 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. See
also
8.
Raise center deck fully up.
9.
Without lowering implement, shut tractor down
properly. Refer to
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.
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
14. 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.
15. Make repairs to cutter and tractor before continuing
with
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 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.
1.
Make sure cutter blades are not locked against each
other. See
2.
Remove support blocks or jack stands and set
transport locks for field operations. See
3.
Lower cutter down until blades are about 2" off the
ground.
4.
Start tractor and set throttle speed just above idle.
Use tractor’s power take-off soft start option if
available. Slowly engage power take-off to get blades
rotating. (See
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 power take-off speed. If cutter vibrates
excessively for 3 seconds at full speed, immediately
disengage power take-off, shut tractor down properly,
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, and bent driveline.
10. Taking proper precautions, make necessary repairs
and adjustments.
11. Repeat steps 1-10 to make certain vibration
problems are fixed before putting cutter back into
service.
IMPORTANT:
Read all
starting on page 32 before operating the cutter.
