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 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

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.
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
Figure 4-18. 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.

WARNING
3. The harrow sections should run level from
front-to-rear when working in the field. Pull the
harrow a short distance at the desired working depth.
Stop the tractor and leave the cultivator\harrow in the
ground, verify that the harrow section is level or
slightly higher in the front.
4. To adjust the harrow section, raise the cultivator till
the harrow clears the ground. Remove the 1/2 x 1-1/4
round head square neck screws from the angle
adjustment plate on both section harrow arms.
Support the back of the harrow section when
removing the botls. Rotate the harrow section to the
desired set of adjustment holes and reinstall the 1/2 x
1-1/4 screws back in the angle adjustment plate.
5. 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
Figure 4-18, loosen both 1-8 hex nuts against the
spring end. 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.
