General Maintenance Information
Proper servicing and adjustments are key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
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.

WARNING
To prevent serious injury or death:
•
Perform maintenance only on equipment that is not
running. Disengage power take-off, place tractor in park or
set park brake, shut tractor engine off, remove switch key,
and wait for all moving components to come to a complete
stop before dismounting tractor.
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and high wear. Make repairs before putting implement back
into service. Serious breakdowns can result in injury or
death.
•
Do not alter implement or replace parts with other brands.
Other brands may not fit properly or meet OEM
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the product.
Replace parts only with genuine OEM parts.
•
Buildup of debris around moving components and
gearboxes is a fire hazard. Keep rotating parts and
gearboxes free from debris to avoid serious injury and
property damage.
•
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level to avoid serious
injury and property damage.
Tractor Maintenance
One of the most important things you can do to prevent
hydraulic system problems is ensure that your tractor's
reservoir remains free of dirt and contamination.
Use a clean cloth to wipe hose ends clean before
attaching them to your tractor. Replace tractor 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
!
WARNING
To prevent serious injury or death:
•
Always disconnect main driveline from the power take-off
shaft before servicing drivetrain and components powered
by the drivetrain. The power take-off can be engaged if
tractor is started causing bodily injury or death.
•
Always secure equipment with solid supports before
working under it. Never work under equipment supported
by concrete blocks or hydraulics. Concrete blocks can
break, hydraulic lines can burst, and/or hydraulic controls
can be actuated even when power to hydraulics is off.
•
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.
•
Do not attempt to straighten a bent blade or weld on a
blade. Do not attempt to modify a blade such as hard
surfacing, heat treating, cold treating, or by any other
method. Always replace blades with new approved blades to
assure safety.
•
Wait for blades to come to a complete stop before accessing
blade bolts through blade bolt access hole.
•
ALWAYS wear eye protection and gloves while inspecting,
removing, sharpening, and replacing a blade.
Always inspect cutting blades before each use. Make
certain they are properly installed and are 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 5-1 on page 34 when
ordering Land Pride replacement blade components.
Remove cutting blades and sharpen or replace as
follows:
1. Place tractor gear selector in park and/or set brakes,
shut engine off and remove ignition key.
2. Disconnect main driveline from tractor power take-off
and secure cutter deck in the up position with solid
supports before servicing underside of cutter.
Refer to Figure 5-1:
3. Remove rubber plug (#5) above cutter blade (#6).
Rotate blade bolt (#1) until in alignment with access
hole (A).
4. Unscrew locknut (#3) to remove cutting blade (#6).
Blade bolt (#1) is keyed and will not turn freely.
5. Both blades should be sharpened at the same angle
as the original cutting edge and must be replaced or
re-ground at the same time to maintain proper
balance in the cutting unit. The following precautions
should be taken when sharpening blades:
a. Do not remove more material than necessary.
b. Do not heat and pound out a cutting edge.
c. Do not grind blades to a razor edge. Leave a blunt
cutting edge approximately 1/16" thick.
IMPORTANT: Cutting 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.
