Driveline Maintenance
Before each use, check that the driveline is securely
fastened and that all driveline shields are in place,
undamaged and in working order. Replace driveline and
shields as needed. Order only genuine Land Pride parts
from your local Land Pride dealer.
DANGER
!
To prevent serious injury or death:
•
Tractor power take-off shaft shield, driveline shields, and
gearbox shaft shields must be installed and in good working
condition to avoid driveline entanglement and projectiles
•
Always disconnect driveline from the tractor before
servicing the drivetrain and components powered by the
drivetrain. A person can become entangled in the drivetrain
if the tractor is started and the power take-off is engaged.
WARNING
!
To prevent serious injury or death:
•
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
•
Do not operate a broken or bent driveline. Such a driveline
will break apart while rotating at high speeds and can cause
serious injury or death. Always remove the implement from
use until the damaged driveline can be repaired or replaced.
Slip Clutch Protected Driveline
The tiller drive components are protected from shock
loads with either a coil spring slip clutch or a Belleville
spring slip clutch. Refer to Figure 1-2 and Figure 1-3 on
page 11 to determine which driveline protection is
included with this tiller. Refer to instructions for
Before each use, check that all driveline shields and
drivelines are in place, undamaged and in working order.
Replace shields and drivelines as needed. Order only
genuine Land Pride parts from your local Land Pride
dealer.

Slip Clutches With Coil Springs
Drive components are protected from shock loads by a
friction slip clutch. The clutch must be capable of
slippage during operation to protect the gearbox,
driveline, and other drive train parts.
WARNING
!
To avoid serious injury or death:
•
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
•
A slip clutch that has been in use or has slipped for as little
as only two or three seconds during run-in may be too hot
to touch. Allow a hot clutch to cool before working on it.
Clutch Run-In
Figure 4-4
Clutch Run-In
Refer to Figure 4-4:
Friction clutches should be “run-in” prior to initial
operation and after long periods of inactivity. To prevent
driveline and gearbox damage, repeat clutch “run-In” at
the beginning of each season and when moisture and/or
condensation seizes the inner friction plates.
1. Using a pencil or other marker scribe a line across the
exposed edges of the clutch plates and friction disks.
2. Carefully loosen each of the 8 spring retainer nuts by
exactly 2 revolutions. It will be necessary to hold the
hex end of the retainer bolt in order to count the exact
number of revolutions.
3. Start the tractor and engage the driveline drive for
2-3 seconds to permit slippage of the clutch
surfaces. Disengage the driveline, then re-engage a
second time for 2-3 seconds. Disengage driveline,
shut off tractor, and remove key. Wait for all
components to stop before dismounting from tractor.
IMPORTANT:
Prior to initial operation and after 10
days of inactivity, slip friction disks to remove
oxidation and moisture. Moisture allows disks to slip
easily. Oxidation can prevent disk from slipping
causing driveline damage. This damage is NOT
