Depth Stop Adjustment (Manual)
The operating depth of the Disc 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 4-12.) Turn the handle out
(counter-clockwise) to decrease operating 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.

OPERATION AND MAINTENANCE
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 (See Figure 4-11.)
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 seal(s) onto the spindle. Do not install the
seal into the hub. The 2211-09 & -11 models use (1)
triple lip seal. The 2211-13 & -15 models use (2)
single seals.
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 seal to the hub and install the seal in the
hub.
NOTE
The triple-lip seals (2211-09 & -11) and both single seals
(2211-13 & -15) 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.
Hydraulic Maintenance
1. Check the tractor hydraulic fluid level per tractor
owners manual and after any leakage. Check fluid
level with the cylinders in the retracted position.
2. If a cylinder or valve leaks, disassemble the parts to
determine the cause of the leak. Any time a cylinder
is opened up, or whenever any seal replacement is
necessary, it is advisable to clean all parts and
replace all seals. Seal kits are available from your
Landoll dealer.
3. Check all hydraulic hoses weekly. Look for binding or
cracking. Replace all worn or defective parts
immediately.
