OPERATION AND MAINTENANCE
Wheel Bearing Maintenance
1. Check wheel bearings and coulter bearings
occasionally for excessive end play. To correctly
replace the wheel bearings:
2. Place the frame on blocks or stands sufficient to lift
the tire clear of the ground.
3. Remove the hub cap, cotter pin, slotted nut, and
washer.
4. Remove the hub. Clean and inspect the bearings and
hub cavity. Replace any worn or defective parts.
5. Repack the bearings using a high-quality wheel
bearing grease.
6. Replace the hub with a new seal and inner bearing in
place.
7. Install the outer bearing cone, washer, and slotted
nut.
8. Tighten the slotted nut while rotating the hub until
there is a slight resistance to wheel rotation. Back the
slotted nut off one notch until the wheel rotates freely
without end play.
9. Install a new cotter pin and the hub cap.
10. Wheel bearing maintenance should be performed at
the beginning of every season of use.
Coulter Spring Adjustment
1. No spring adjustment is necessary on the coulters.
All adjustments were made before shipping at the
factory. Initial operating force to move coulter
upwards is 540 pounds. The preload has proved to
be more than adequate for most conditions.
Any attempt to make coulter force greater than
factory setting may contribute to premature
failure of parts and warranty shall be null and
void.

CAUTION
Lubrication
IMPORTANT
Items with grease zerks are listed in the illustrated
parts book.
1. Besides repacking the wheel bearings, described in
"Wheel Bearing Maintenance" on page 4-4, spring
clamp pivot points should be lubricated with a high
grade multi-purpose grease twice a day or after every
five hours of operation.
2. Lubricate the fittings on the shank pivot hollow bolts
daily or after ten hours of use.
3. Grease coulter hub and swivel mount casting after
twenty hours of use.
Hydraulic Maintenance
1. If a cylinder leaks, disassemble the part to find the
cause of the leak. Any time a cylinder is opened up,
or whenever any seal replacement is needed, it is
advisable to clean all parts and replace all seals.
Seal kits are available from your Landoll dealer.
2. Check all hydraulic hoses weekly. Look for binding or
cracking. Replace all worn or defective parts
immediately.
Storage
1. The service life of the In-Row Ripper will be extended
by proper off-season storage practices. Before
storing, complete the following procedures:
2. Completely clean the unit.
3. Inspect the machine for worn or defective parts.
Replace parts as needed to avoid delays the
following season.
4. Repaint all areas where the original paint film is worn
off.
5. Grease all exposed metal surfaces of shanks, points,
and coulters.
6. Lubricate as suggested in "Lubrication" on
page 4-4.
7. Store the unit in a shed or under a tarpaulin to protect
it from the weather. The ground tools and tires should
rest on a board or other device to keep them out of
the soil.
