c. Adjust the harrow gang bar plate (p/n 154993)
angle by removing 1/2-13 x 1-1/4 round head
square neck screws as shown in Figure 4-16.
Rotate the harrow section to the desired level
position and reinstall the bolts in the appropriate
mounting holes to hold the harrow section level.
d. Entire harrow sections may be leveled for height
and side-to-side. Sections heights may be
leveled for all sections across the back of the
implement, or individually for side-to-side
levelness. To adjust the section heights, see
Figure 4-16. Loosen the locking nuts on the 1x9
spring bolt, and then rotate the bolt head to raise
or lower the section. Retighten the bolts when
finished.
e. The tine tooth angle may be adjusted for a
steeper more aggressive tooth angle or for a
lower or flatter tooth angle. Use steeper tooth
angles for clean or minimal residue conditions. A
flatter tooth angle will allow the harrow to clear
heavier and/or wetter residue. The tine tooth
angle is set for each row by removing the spring
clip pin at each tine angle adjustment handle and
positioning to the desired hole.
OPERATION AND MAINTENANCE
IMPORTANT
In some conditions it may be desirable to run the tine
rows at slightly different tine angles.
Example: Lower tine angle on the front row may help
to start heavy residue under the harrow.
f. For initial harrow settings for the disc, refer to
Figure 4-16. These are initial settings to get
started. Actual field conditions (soil types,
residue, moisture, etc.) may require additional
adjustment. For best results, adjust one section
until the desired finish is obtained. Then set the
rest of the harrow sections to match.
2. Maintenance
a. The coil tine harrow does not have any
lubrication points. Harrow arms pivot on
maintenance-free bearings. Keep the harrow
clean from residue and excess soil. Thoroughly
clean the entire harrow before long term storage.

Coil tine teeth wear very sharp. Use caution when
working near the coil tine harrow attachment.
