Figure 4-11: 4 Row Coil Tine Harrow
4 Row Coil Tine Harrow
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 (See Figure 4-11.) 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. Each harrow section may also be adjusted for
operating height. To change the harrow height,
loosen the locking nut against the threaded end of
the spring. Raise or lower the harrow arm by turning
the bolt head for the spring adjustment bolt. Then
retighten the locking nut against the spring. 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.
NOTE
The tine teeth will hang straight down when the
implement is raised, and the tines will be slightly lower
than the sweeps.
