OPERATION AND MAINTENANCE
3 Row Spike and Reel
Adjustments
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.
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. 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 three 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. For the most aggressive spike tooth action, install the
harrow adjustment pin in the forward mounting hole
over each bar clamp for each spike bar
Figure
4-16) 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 middle
or rear hole. This will allow the teeth to lay flatter and
shed more residue.
4. 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 for
increased leveling. 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 extend 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.

WARNING

5. The 12" diameter reel consists of nine 3/4" diameter
round 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.A 12" diameter spiral wound reel with 1/4 s
1-1/2 angled blades is also available. The blades on
flat bar reels are angled for more aggressive action.
Install the reels as shown
Figure 4-15: Flat 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 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.
8. Reels are equipped with maintenance-free bearings.
