Section 4: Maintenance and 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.
!
DANGER
To avoid serious injury or death: Always secure equipment
with solid, non-concrete supports before working under it.
Never go under equipment supported by concrete blocks or
hydraulics. Concrete can break, hydraulic lines can burst,
and/or hydraulic controls can be actuated even when power to
hydraulics is off.
!
WARNING
To avoid serious injury or death:
•
Always follow "Tractor Shutdown Procedure" provided in
this manual before dismounting the tractor.
•
Allow only persons to perform maintenance on this
implement who have been properly trained in its safe
operation.
•
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.
•
Before any adjustments or maintenance is performed, lower
implement to ground, shut engine off, and remove switch
key. Do not attempt to make adjustments or perform
maintenance with implement or power machine running.

WARNING
To avoid serious injury or death:
Used tines can be very sharp. Always wear gloves when
handling tines to protect against cuts.
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.
1.
Remove the two hex nuts, lock washers, bolts, and
tine to be replaced.
2. Attach new tine to the mounting flange making
certain it is positioned so that the cutting edge

crosses over the mounting flange and leads in
rotation as shown in Figure 4-1 for the RTR12 Series
or in Figure 4-2 for the RTA12 Series.
3. Replace removed 1/2"-20 x 1 1/4" GR5 bolts, lock
washers, and hex nuts. Tighten hex nuts to the
correct torque.

Driveline Protection
Tiller drive components are protected from shock loads
with a two plate friction clutch.
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.
Clutch Run-In
The clutch must be capable of slippage during operation
to protect gearbox, driveline and other drivetrain parts.
Friction clutches should be "run-in" prior to initial
