Section 8: Maintenance & Lubrication
Maintenance
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 after using the unit for several hours to be
sure they are tight. Replace any worn, damaged, or
illegible safety labels by obtaining new labels from your
Land Pride dealer.
!
DANGER
To avoid serious injury or death:
Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment supported
by concrete blocks or hydraulics. Concrete can break,
hydraulic lines can burst, and/or hydraulic controls can be
actuated even when power to hydraulics is off.
!
WARNING
To avoid serious injury or death:
•
Do not alter implement or replace parts on the implement
with other brands. Other brands may not fit properly or
meet OEM (Original Equipment Manufacturer)
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the implement.
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.
Rotary Cutter Blades
!
DANGER
To avoid serious injury or death:
Always disconnect driveline from power take-off shaft before
servicing underside of cutter. The tractor can be started with
power take-off engaged.
!
WARNING
To avoid serious injury or death:
Do not operate cutter with blades that are out-of-balance,
•
bent, excessively worn, excessively nicked, or with blade
bolts that are excessively worn. Such blades can break loose
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 Land Pride blades
to assure safety.

Inspect cutting blades before each use. Make certain they
are properly installed and are in good working condition.
Replace any blade that is damaged, bent, worn, or
excessively nicked. Small nicks can be ground out.
IMPORTANT: Replace cutting blades in pairs with
genuine Land Pride blades only. Replacing single
blades can result in an out-of-balance condition that
will contribute to premature bearing wear/breakage
and/or structural cracks in gearbox and/or deck.
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 8-1 on page 55:
3. Remove access cover (#6) and rotate blade bolt (#1)
until in alignment with access hole "A" .
4. Inspect cutting blades. Make certain they are
properly installed and are in good working condition.
Replace any blade that is damaged, bent, worn, or
excessively nicked. Small nicks can be ground out
when sharpened.
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.
d. Always grind cutting edge so end of blade remains
square to cutting edge and not rounded.
e. Do not sharpen back side of blade.
f. Both blades should weigh the same with not more
than 1 1/2 oz. difference. Unbalanced blades will
cause excessive vibration which can damage
gearbox bearings and create structural cracks.
Refer to Figure 8-2 on page 55:
6. Carefully check cutting edges of blades in relation to
blade carrier rotation to ensure correct blade
placement. Blade Rotation is clockwise with cutting
edge leading. Airfoil (lift) must be oriented towards
the top of the deck.
