Landoll 9630 Field Cultivator - Manual (Page 118)

4-8 F-632-0114 Edition
OPERATION AND MAINTENANCE
Depth Stop Adjustment
1. The operating depth of the Field Cultivator is
controlled by a single-point depth stop. The stop is
located at the center front of the machine (See
Figure 4-8.)
2. Adjust the depth stop by turning the handle out
(counter-clockwise) to increase operating depth.
Turn the handle in (clockwise) to decrease operating
depth. One turn will equal approximately 3/16”
adjustment in depth. 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 of each frame
section and does not allow the self-leveler to
function properly.

General Operation
1. The horsepower requirements are typically 6-8 PTO
horsepower per foot of cut for the Field Cultivator.
This will vary widely due to speed, depth, moisture,
residue, and types of soils. Local dealers can help in
making recommendations for your areas.
2. Operating speed is typically 5-8 mph. Excessive
speed can cause the unit to bounce and create
uneven working depth and ridge.
3. Lift wheels must always be in contact with the ground
and carrying some implement weight.
4. Avoid turning sharply with the Field Cultivator in the
ground. This can put excessive side load on the
shanks, harrow, and hitch. Always raise the Field
Cultivator completely when making turns or backing
to prevent shank damage. Reduce speed at field
ends, and raise cultivator before making turns.
LED Light Operation
1. Attach the seven-pin plug to the socket at the rear of
the tractor. The socket must be in good working
order, and free of dirt, grease, and corrosion. The
connection must be clean with good contact for the
LED light to function properly. Fully insert the plug
into the connector and make sure the latch securely
hooks the plug.
2. Allow enough cable above the hitch to allow for
turning. Secure or tie up any excess cable to prevent
it from catching on the hitch or stalks.
3. Verify proper light function before transporting.
Replace or repair any component that is damaged or
not functioning. Make sure all lighting is clean and
clearly visible. Follow local regulations regarding
lighting & marking.
