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 bolts and pins after using 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.
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:
•
For safety reasons, each maintenance operation must be
performed with harrow lowered completely to the ground or
safely supported on blocking with tractor park brakes
engaged, engine shut off and ignition key removed.
•
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.
Tractor Maintenance
One of the most important things you can do to prevent
hydraulic system problems is ensure that your tractor's
reservoir remains free of dirt and contamination.
Use a clean cloth to wipe hose ends before attaching
them to your tractor. Replace your tractor’s hydraulic filter
element at the prescribed intervals. These simple
maintenances will go a long way to prevent occurrence of
control valve and hydraulic cylinder problems.
Tires
It is important that the tires on the harrow have correct air
pressure. Check air pressure in all four tires before each
use and visually inspect tires for loss of air throughout
each day of operation. The wing tires require less air
pressure than the center two tires. See “Tire Inflation
Chart” on page 26 for correct air pressure ratings.
Spike Tooth Replacement
Always inspect spike teeth before each use. Make certain
they are properly installed and are in good working
condition. Replace any tooth that is lost, worn excessively
or broken as follows:
1.
Place tractor gear selector in park and set brakes,
shut engine off and remove ignition key.
2. Secure harrow with solid supports before servicing
underside of harrow.
3. Remove 1/2”-13 locknut (#2) and spike tooth (#3)
from harrow bar (#1).
4. Insert new spike tooth (#3) in harrow bar (#1) and
secure with 1/2”-13 new locknut (#2). Tighten locknut
to the correct torque.

NOTE:
Always replace spike teeth and locknuts at
the same time to insure that the locknuts will not
come loose and allow the spike teeth fall off.
