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 and pins after using the unit 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
!
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.
•
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 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.
•
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.

Driveline Slip-Clutch
The drive-train is protected from shock loads with a four
plate slip-clutch. The slip-clutch must be capable of
slippage during operation. Always do a
“Clutch Run-In”
operation at the beginning of each season and after long
periods of inactivity to remove any oxidation that may
have accumulated on the friction surfaces. Repeat
“Clutch Run-In” instructions below when moisture
and/or condensation seizes the inner friction plates.
WARNING
!
To avoid serious injury or death:
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
Clutch Run-In
Refer to Refer to Figure 5-1:
Clutch
Figure 5-1
1. Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction
discs.
2. Carefully loosen each of the 8 spring retainer nuts by
exactly 2 revolutions. It will be necessary to hold hex
end of retainer bolt in order to count the exact
number of revolutions.
3. Start tractor and engage power take-off drive for 2-3
seconds to permit slippage of the clutch surfaces.
Disengage power take-off, then re-engage a second
time for 2-3 seconds. Disengage power take-off, shut
off tractor, and remove key. Wait for all components to
stop before dismounting from tractor.
4. Inspect clutch and ensure that the scribed markings
made on the clutch plates have changed position.
Slippage has not occurred if any two marks on the
friction disc and plate are still aligned. A clutch that
has not slipped must be disassembled to separate
the friction disc plates. See
“Clutch Assembly and
Disassembly” on page 37.
5. Tighten each of the 8 spring retainer nuts on the
clutch housing exactly 2 revolutions to restore the
clutch to the original setting pressure.
6. The clutch should be checked during the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
See Figure 5-3 on page 37 to adjust spring length.
