Section 4: 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 hardware after several hours of operation and
regularly 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 avoid serious injury or death:
•
Allow only persons to perform maintenance on this
implement who have been properly trained in its safe
operation.
•
Before any adjustments or maintenance is performed, lower
implement to ground, shut engine off, and remove switch
key. Do not attempt to make adjustments with implement or
power machine running.
•
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.
Tine Replacement
Refer to Figure 4-1:
WARNING
!
To avoid serious injury or death:
Used tines can be very sharp. Always wear gloves when
handling tines to protect against cuts.
1. Remove two 1/2
"
-20 x 1 1/4
"
GR5 hex head cap
screws (#1), hex nuts (#2), and lock washers (#3).
Remove tine (#4).
2. Attach each new tine to the flange making certain it is
mounted so that the cutting edge crosses over the
flange and leads in rotation as shown in Figure 4-1.
3. Replace cap screws and fasteners (#1, #2 & #3).
Tighten nuts to proper torque. See
The Torque Values
Chart in the “Appendix” section on page 27.
IMPORTANT: When ordering tines, be sure to order
only genuine OEM tines and to order both right- and
left-hand tines. Always install tines with cutting edge
facing the direction of rotation.
IMPORTANT: Remove and install one tine at a time
to ensure they are oriented correctly when installed.

Driveline Protection
DANGER
!
To avoid serious injury or death:
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting the
tractor.
Tiller drive components are protected from shock loads
by either a two plate friction clutch or a shear bolt. Avoid
shear bolt failure by engaging the power take-off slowly at
low engine rpm. See your Land Pride dealer when
replacing shear bolts. Torque shear bolt nuts to 8 ft. lbs.
Clutch Run-In
Friction clutches should be “run-in” prior to initial
operation and after long periods of inactivity. To prevent
driveline and gearbox damage, repeat “Run-In”
instructions at the beginning of each season and when
moisture and/or condensation seizes the inner friction
plates.
Refer to Figure 4-2 on page 20:
1. Using a pencil or other marker scribe a line across the
exposed edges of the clutch plates and friction disks.
