4 Row Coil Tine Harrow Adjust-
ments
1. The 4 row coil tine harrow option has 4 rows of 7/16”
diameter x 18” long spring steel tines on 16” centers
with overall spacing of 2” working centers. Tine rows
are on 13” centers for enhanced residue flow. Tine
tooth angle is also adjustable from the rear of each
section. Each harrow section is mounted with two
arms with spring-loaded down pressure. Tine teeth
may individually rotate freely backward if needed for
backup protection
WARNING
2. In general tine harrows have better capabilities for
handling more residue and wetter conditions. When
operating the coil tine harrow, a more vertical tine
tooth angle will make the harrow more aggressive. A
lower/flatter tine angle will make the harrow less
aggressive but will handle more residue and wetter
conditions. To change the tine angle, raise the harrow
off the ground. Remove the harrow pin from both
angle adjustment tubes per tine gang bar tube
See
Figure 4-12 . Rotate the angle adjustment tubes
forward (less aggressive) or rearward (more
aggressive) and reinstall both spring clip pins. Repeat
the tine adjustment for each tine gangbar tube and
harrow section.
3. The initial setting for the spring assembly should be
22”. Each harrow section may also be adjusted for
operating height. To change the harrow height
See
Figure 4-12 , loosen both 1-8 hex nuts. Raise or lower
the harrow arm by turning the bolt head for the spring
adjustment bolt. Then re-tighten the 1-8 hex nuts.
When initially setting the harrow height, the bottom
tips of the tine tooth (pulled back at the desired tooth
angle) should be approximately level with the field
cultivator sweeps.
Know and verify actual implement height and
width before transporting. Attachments may
increase the overall height and width of the
implement. Use caution when transporting near
power lines. Electrocution can occur without
direct contact.
