OPERATION AND MAINTENANCE

Gauge Wheel Adjustment
Figure 4-3: Gauge Wheel Adjustment
1. For stability, the gauge wheels must always apply
slight pressure against the soil. Adjust the gauge
wheels by raising or lowering, as needed, to reach
proper depth. To reach proper depth (See Figure
4-3):
a. remove the screw in the gauge wheel shaft
b. make the proper adjustment
c. reinstall the screw
d. tighten the screw and lock nut until the gauge
wheel is securely clamped into position.
2. There are several points to consider when setting the
gauge wheel depth:
a. When the cultivator is in the ground and the
depth is set, the tool frames should tip slightly
forward. This is done by raising or lowering the
gauge wheels and adjusting the tractor top
adjustment link.
b. On very soft or loamy soil, it may be necessary to
set the gauge wheels directly behind the tractor
tires a little different than the others. This allows
their respective sweeps to maintain the same
depth as the other sweeps.
c. The depth should be sufficient to move the
desired amount of soil and to get the sweep into
good, solid soil during high trash situations.
Coulter Adjustment
Figure 4-4: Coulter Adjustment
Initial setting for a coulter is at least one inch below the
working depth of the sweeps. Generally, the harder the
soil, the less pressure used on the coulters. To adjust
coulters (See Figure 4-4):
1. Remove the 1/2-13 X 8-1/2 hex head cap screw that
goes through the coulter brace and the tool frame
mount.
2. Raise or lower the entire coulter fork assembly until
the proper height is reached. Use the lower two holes
in the coulter brace for 18" coulters (standard). Use
the next two holes (above) for the 20" inch coulter
option (See Figure 3-5.)
3. Reinstall the 1/2-13 X 8-1/2 hex head cap screw and
the hex lock nut through the coulter braces and tool
frame mount. Extra holes are also provided on the
lower coulter braces for more adjustment.
IMPORTANT
The coulters directly behind the tractor tires may
need to be set slightly different than the other
coulters.
