Now that you’re prepared and well briefed, you may begin harrowing. You will need to maintain a 7 to
10 MPH ground speed to shatter residue. Make a tractor gear and range selection that will enable you
to maintain these speed combinations.
Avoid crossing the face of steep slopes and sharp drops. Cross diagonally through dips to prevent
hanging up the tractor and harrow. When turning, use slower speeds and make wide turns when
possible. The three-point hitch should be lifted into transport position to make tight turns and to turn
around in the field. Try increasing or decreasing ground speed to determine the effect on quality of
work. Remember to look back often.
With a little practice you will be pleased with what you and your Spike Tooth Harrow can do. Whether
you have finished harrowing, need to take a break, or just need to make adjustments to the harrow,
remember to:
reduce the tractor engine’s RPM,
stop the unit on level ground,
set the tractor park brake,
turn off the engine, and
remove the key before dismounting the tractor.
After Each Use
When not hooked to a tractor, the hitch can fall backwards unexpectedly, causing bodily injury. Store
the harrow with the hitch pivoted down onto the harrow frame.
Un-hooking the Spike Tooth Harrow from the Tractor
1. Park on a level, solid surface.
2. Lower the harrow to just off the ground, or onto blocks that support the harrow spike teeth
above ground.
3. Engage the tractor park brake, shut the tractor engine off, and remove the key before
dismounting the tractor.
4. Fold the spike teeth to the angle shown with the bolt (#4) in the center hole of the adjustment
bar (#1) and the top hole in the lever arm (#3).
5. Un-hook the 3-point hitch (#2) from the tractor. Reinstall the hitch pins, linch pins, and hair pin
cotters in the harrow hitch frame.
6. Lay the hitch frame (#2) down onto the adjustment bar (#1).
