OPERATION AND MAINTENANCE
4-17
3 Row Coil Tine and Reel Harrow
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 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
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
adjustment pin from the rear of both harrow arms for
the harrow section (See Figure 4-14.) 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.
4. 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.
5. To adjust the reel height, loosen the locking hex nut
against the threaded spring end.
6. Raise or lower the reel by turning the head of the
spring bolt, and then retighten 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.
Storage
1. The service life of the Field Cultivator will be
extended by proper off-season storage practices.
Prior to storing the unit, complete the following
procedures:
a. Completely clean the unit.
b. Inspect the machine for worn or defective parts.
Replace as needed.
c. Repaint all areas where the original paint film is
worn off.
d. Grease all exposed metal surfaces of shanks,
points.
e. Lubricate each point of the machine as stated in
“Lubrication” on page 4-10.
f. Store the unit in a shed or under a tarpaulin to
protect it from the weather. The ground tools and
tires should rest on boards, or some other object,
to keep them out of the soil.
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.
