OPERATION AND MAINTENANCE
4-15
3 Row Spike and Reel Harrow
1. The optional 3 row spike and reel attachment
consists of a 3 row spike and finishing reel
combination harrow that operate independently from
each other. The 3 row spike reel harrow performs
best in clean dry ground with minimal residue, to
level, break up clods, and firm soil.

WARNING
2. The 3 row spike consists of 3 rows of 3/4” x 14” long
spike teeth, spaced on 9” centers. The spike teeth
effectively work on 3.6” centers. Rank spacing for the
angle iron bars is 14”. Angle iron bars are able to
float over contours and have backup protection.
Spike tooth angle has a two position adjustment to
either stand the teeth up for more aggressive action,
or to lay the teeth down for less aggressiveness and
better residue clearance.
3. The 12” diameter reel consists of eight 3/4” diameter
bars with a chevron shape for smoother rotation. The
reels have no inner shaft to reduce plugging in wetter
conditions. The reels operate independently of the 3
row spike with two spring loaded arms per reel to
maintain consistent down pressure.
4. For the most aggressive spike tooth action, install the
harrow adjustment pin in the mounting hole over
each bar clamp for each spike bar (See
Figure 4-13.) This will position the spike teeth to be
in the most vertical position. In wetter or conditions
with some residue, lower the spike tooth angle by
positioning the harrow adjustment pin in the storage
locations away from the bar clamps. This will allow
the teeth to lay flatter and shed more residue.
5. The forward pull chain will also influence how the 3
row spike operates as well. A taller pull point and
shorter adjusted pull chain can help to start residue
through the harrow. A lower pull point with a longer
adjusted pull chain will help the entire harrow to run
flatter from front-to-rear, and be more aggressive.
When adjusting the pull chain, insert the desired
pulling link through the slotted hole in the pull chain
bracket, and install a lynch pin thru the link to secure
the chain in place. Make sure the pull chains are set
evenly for each section. Also do not let the pull chain
out so far that the vertical carrying chains are pulling
the harrow through the field, or that the spike harrow
gets into the reel.
6. To adjust the reel height, loosen the locking hex nut
against the threaded spring end.
7. 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.
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.
