OPERATION AND MAINTENANCE
5 Row Spike Harrow
Adjustments
1. The 5 row spike harrow optional attachment consists
of 5 rows of 3/4” x 14” long spike teeth, spaced on 9”
centers. The spike teeth effectively work on 1.8”
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 tooth down
for lower aggressiveness and better residue
clearance. The 5 row spike harrow performs best in
clean ground with minimal residue, to level and break
up clods.

WARNING
2. For the most aggressive spike to action, install the
harrow adjustment pin in the forward mounting hole
over each bar clamp for each spike bar
See
Figure 4-17 . 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.
3. The forward pull chain will also influence how the 5
row spike operates as well
See Figure 4-17 . 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.
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.
