OPERATION AND MAINTENANCE
4 Row Coil Tine Harrow
Adjustments
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 14” 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 adjustment pin
from the rear of both harrow arms for the harrow
section
Rotate the angle
adjustment tubes forward (less aggressive) or
rearward (more aggressive) and reinstall both spring
clip pins. Repeat the tine adjustment for each harrow
section.
3.
The initial setting for the spring assembly should be
21-21/32” Each harrow section may also be adjusted
for operating height. To change the harrow height
, 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.
