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 two 1/2 -20 x 1 1/4
"
screws (#1), hex nuts (#2), and lockwashers (#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

Driveline Protection

!
CAUTION
Engage parking brake, disengage PTO, shut off tractor, and
remove key before making any of the following adjustments.
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 PTO slowly at low
engine rpm. See your Land Pride Dealer when replacing
shear bolts. Torque shear bolt nuts to 8 ft. lbs.

Note: If M6 bolt shears excessively, a 1/4

may be used. A 1/4 -20 GR8 bolt is not recommended as it may
cause damage to profiles, tiller frame, and/or components.

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.
