OPERATION AND MAINTENANCE
3 Row Coil Tine and Reel
Adjustments
1. The optional 3 row coil tine and reel attachment
consists of a 3 row coil tine and finishing reel
combination harrow that operate independently from
each other. The 3 row coil tine reel harrow performs
best in clean dry ground with minimal residue, to
level, break up clods, and firm soil.
2. The 3 row coil tine harrow option has 3 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 for each tine bar end
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.
3. 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
4-19. 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 gang bar
tube and harrow section.

WARNING
4. 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.
5. 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.
6. Each coil tine harrow may be adjusted for spring
pressure as well
harrow off the ground. Remove the clevis pin from
the spring tube and install in a heavy or light setting
as needed. Excessive spring pressure and tine
angle can overload harrow spring.
NOTE
The tine teeth will hang straight down when the
implement is raised, and the tines will be slightly lower
than the sweeps.
7. To adjust the reel height, loosen the locking hex nut
against the threaded spring end
8. Raise or lower the reel by turning the head of the
spring bolt, and then re-tighten the locking nut
against the spring end. Initially set the bottom of the
reel even with the bottom of the sweeps. In lighter or
wet soils, you may need to raise the reels slightly
above the sweeps. Setting the reels too low may
cause the reels to plug or push dirt. Excessive reel
depth/down pressure may hold the rear of the field
cultivator out of the ground.
