OPERATION AND MAINTENANCE
Chopper Reel & 3 Row Spike
The chopper reel and 3 row spike harrow operate
1.
independently to offer a very aggressive harrow for
chopping and mixing soil and residue. The 16" dia
reel helps to break up clods and mix the soil,
followed by a 3-row spike harrow to smooth and
level the soil. The chopper reel and 3 row spike will
perform best in clean dry ground with minimal
residue. Chopper reels are angled throw soil the
opposite direction as the disc gang reels to help
smooth and level 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.
2. Reel height is adjustable from 1" above the bottom of
the sweeps to 3-1/2" above the sweep
Figure
4-24. Initially the reels are set in the lowest
position, which is 1" above the sweeps. The front and
rear set of holes adjust in 1-1/4 increments, while the
intermediate holes at the rear are in 5/8" increments.
Keep the reel level as possible when making
adjustments. To adjust the reel height, place a block
under the reel to prevent the reel from falling. Lower
the finisholl till the bottom two blades of the reel rest
on the block. Do not try to support the reel on a
single blade to prevent rolling. Loosen the front and
rear reel mounting bolts for both reel harrow arms.
Remove either the front or rear mounting bolts, but
not both. Rotate the reel to the next higher or lower
position and then reinstall the bolts. Adjust the
opposite end of the reel mount as needed. Retighten
the mounting bolts when finished. All reels should be
set the same height across the machine.
Chopper reels are heavy and sharp. Use caution
and support the reels when making adjustments.
3. Chopper reels should be installed as shown
Figure 4-23
for correct chopping operation (Note the
direction of travel). If the reels are installed
backwards, the blade will contact the ground at a
much flatter angle, and not chop or mix the soil as
well.

Figure 4-23: Chopper Reel Direction
Chopper reels prefer drier soils. Working the ground
4.
when the soil is too wet or too deep will cause the
reel to plug. The aggressive action of the chopper
reel tends to work deeper than typical finishing
reels. Use caution when working in wetter
conditions not to run the chopper reel too deep.
Make sure the finisholl's depth is correct and the
implement is running level front-to-rear.
9. 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.
10. 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 4-24
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.
11. 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.
