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.
!
CAUTION
Do not alter Land Pride equipment or replace parts with other
brands. Doing so can cause equipment to perform improperly
and may lead to breakage that can cause bodily injury.
Replace parts only with genuine Land Pride parts.
!
CAUTION
Buildup of debris around moving parts and gearboxes is a fire
hazard. Keep rotating parts and gearboxes free from debris to
avoid serious injury and property damage.
!
CAUTION
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level to avoid serious
injury and property damage.
Slip-Clutch Protected Drivelines
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
Always disengage PTO, engage parking brake, shut off
tractor, remove ignition key, and wait for all moving parts to
come to a complete stop before dismounting tractor to make
adjustments.
Clutch Run-In
Refer to Refer to Figure 4-2:
Clutch
Figure 4-2
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 PTO drive for 2-3 seconds
to permit slippage of the clutch surfaces. Disengage
PTO, then re-engage a second time for 2-3 seconds.
Disengage PTO, 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 30.
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 4-4 on page 30 to adjust spring length.
