OPERATION AND MAINTENANCE
Depth Stop Adjustment (Manual)
The operating depth of the Coulter Chisel is controlled by
a single-point depth stop. The stop is located at the
center front of the machine.
1. Adjust the depth stop by turning the handle in
(clockwise) to increase operating depth (See
Figure 4-7.) Turn the handle out (counter-clockwise)
to decrease operating depth. One turn will equal
approximately 3/16” adjustment in depth.

2. The gauge on the side of the depth stop tube gives a
reference for depth setting. The “A“ setting refers to
maximum operating depth.
IMPORTANT
For maximum operating depth, the lift wheels must
be in contact with the ground and carry some of the
machine weight. Raising the lift wheels off the
ground permits uncontrolled depth and does not
allow the leveler to function properly.
Wheel Bearing Maintenance
Wheel bearing maintenance should be performed at the
beginning of every season of use. Check the wheel
bearings periodically for excessive end play. If needed,
adjust or replace them using the following procedure:
1. Place the frame on blocks or stands sufficient to lift
the tire clear of the ground.
2. Remove the tire.
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. Slide the triple-lip seal onto the spindle. Do not install
the seal into the hub.
7. Slide the inner bearing cone and hub onto the
spindle.
8. Install the outer bearing cone, washer and slotted
nut.
9. Tighten the slotted nut while rotating the hub until
there is a slight resistance to wheel rotation. Then,
back the slotted nut off one notch, until the wheel
rotates freely without end play.
10. Slide the triple-lip seal to the hub and install the seal
in the hub.
NOTE
The triple-lip seals should point away from the hub to
keep contaminants out and allow grease to pass.
11. Install a new cotter pin and replace the hub cap.
