General Maintenance Information
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
The parts on your Rotary Cutter have been specially
designed and should only be replaced with genuine Land
Pride parts. Do not alter the cutter in a way which will
adversely affect its performance.
Check all bolts and pins after using the cutter for several
hours and on a regular basis thereafter to ensure they
are tight and secured. Replace worn, damaged, or
illegible safety labels by obtaining new labels from your
Land Pride Dealer.
!
DANGER
Perform maintenance only on a cutter that is not running.
Disengage PTO, place tractor in park or set park brake, shut
tractor engine off, remove switch key, and wait for blades to
come to a complete stop before dismounting tractor to perform
maintenance!
!
WARNING
Frequently check all hardware to make certain it is tight and
not broken or missing. Such hardware can cause the cutter to
not perform properly and may lead to breakage that can cause
bodily injury or death.
!
WARNING
Replace worn, damaged, or missing parts only with genuine
Land Pride parts. Replacing parts with other brands can
cause the equipment to not perform properly and may lead to
breakage that can cause bodily injury or death.
!
CAUTION
Do not alter the Rotary Cutter in a way which will adversely
affect its performance or reliability. Doing so can damage the
cutter, cause personal injury and void the warranty.
Tractor Maintenance
One of the most important things you can do to prevent
hydraulic system problems is to ensure your tractor's
hydraulic reservoir remains free of dirt and other
contaminations. Use a clean cloth to wipe hose ends
clean before attaching them to your tractor. Replace your
tractor’s hydraulic filter element at the prescribed
intervals. These simple maintenances will go a long way
to prevent occurrence of control valve and hydraulic
cylinder problems.
Cutter Blade Maintenance
!
DANGER
Always disconnect main driveline from tractor PTO before
servicing underside of cutter. PTO can be engaged if tractor is
started causing cutter damage, bodily injury or death.
!
DANGER
Always secure cutter deck in the up position with solid
supports before servicing underside of cutter. Never work
under equipment supported by hydraulics. Hydraulics can
drop equipment if controls are actuated or if hydraulic lines
burst. Either situation can drop the cutter instantly even when
power to the hydraulics is shut off.
!
WARNING
Keep blade bolt access hole covered at all times except when
servicing cutter blades. Make sure driveline is disconnected
from tractor PTO shaft before servicing cutter blades.
!
WARNING
Do not operate cutter with blades that are bent, out of balance,
excessively worn, excessively nicked, or with blade bolts that
are excessively worn. Such blades can break loose from the
cutter at high speeds causing serious injury or death.
!
CAUTION
ALWAYS wear gloves and eye protection while inspecting,
removing, sharpening, and replacing cutter blades.
Always inspect cutting blades before each use. Make
certain they are properly installed and in good working
condition. Replace any blade that is damaged, worn,
bent, or excessively nicked. Never try to straighten a bent
blade! Small nicks can be ground out when sharpening.
Refer to Figure 5-2 on page 33 when ordering Land Pride
replacement blade components.
Remove cutting blades and sharpen or replace as
needed:
1. Place tractor gear selector in park and/or set brakes,
shut engine off and remove ignition key.
2. Disconnect main driveline from tractor PTO and
secure cutter deck in the up position with solid
supports before servicing underside of cutter.
IMPORTANT: Replace cutting blades with genuine
Land Pride blades only. Blades must be replaced in
mating pairs. Not replacing both blades will result in
an out-of-balance condition that will contribute to
premature bearing breakdown on the spindle hub
and create structural cracks in the cutter housing.
