Operation/Adjustment

NOTE
In general, the harrow should run level front to rear
behind the disc.
1. 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 4-17. Rotate the harrow
section to the desired level position and reinstall the
bolts in the appropriate mounting holes to hold the
harrow section level.
2. 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 4-17. Loosen the locking
nuts on the 1 x 9 spring bolt, and then rotate the bolt
head to raise or lower the section. Retighten the bolts
when finished.
3. 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.
4. For initial harrow settings for the disc, refer to Figure
4-18. 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.

Maintenance

1. 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.
