Section 4: Maintenance & Lubrication
Maintenance
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly down time and repair.
The parts on your Rotary Tiller have been specially
designed and should only be replaced with genuine Land
Pride parts. Do not alter the tiller in a way which will
adversely affects its performance.
Check all bolts and pins after using the unit for several
hours and on a regular basis thereafter to insure they are
tight and secured.
Replace worn, damaged, or illegible safety labels by
obtaining new labels from your Land Pride Dealer.
!
CAUTION
For safety reasons, each maintenance operation must be
performed with tractor PTO disengaged, tiller lowered
completely to the ground or onto support blocks, tractor
engine shut off, and ignition key removed.
Tine Replacement
Refer to Figure 4-1:
!
WARNING
Worn tines may be very sharp!
IMPORTANT: When ordering, be sure to order
genuine Land Pride replacement tines only and to
order both right and left-hand tines. Always install
tines with cutting edge facing direction of rotation.
IMPORTANT: Remove and install one tine at a time
to ensure they are oriented correctly when installed.
1. Remove 2 hex head cap screws and fasteners from
each tine being replaced. Remove tine.
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 2 cap screws and fasteners. Tighten nuts to
proper torque.

Driveline Protection
Tiller drive components are protected from shock loads
with either a two plate friction clutch or a shear bolt.
Shear bolt protection is discussed on page 25.
Friction clutches should be "run-in" prior to initial
operation and after long periods of inactivity to remove
any oxidation that may have accumulated on the friction
surfaces. 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 below and Figure 4-3 on page 25 to
determine which friction clutch your tiller has. Follow
run-In, disassembly, and assembly instructions for your
specific clutch.
Clutches With 4 Adjusting Nuts
Clutch Run-In
Refer to Figure 4-2 (View - A):
1. Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction disks.
2. Tighten all 4 nuts uniformly until spring load is low
enough that the clutch slips freely with PTO
engaged.
3. Start tractor and engage PTO for 2-3 seconds to
permit slippage of 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 disk and plate are still aligned. A clutch that
has not slipped must be disassembled to separate
the friction disk plates. See "Clutch Disassembly &
Assembly" on page 24.
Refer to Figure 4-2 (View - B):
5. Turn all 4 nuts fully back if no two marks on the
friction disk and plate are still aligned. Clutch is ready
for use.
6. The clutch should be checked during first hour of
22269
tilling and periodically each week. An additional set
of scribe marks can be added to check for slippage.
