Adjusting the harrow section aggressiveness (figures 5 and 6)
In the least aggressive direction there are three attachment points for the pull chains on the harrow
section. Moving it up will cause the section to lay more flat (less aggressive) and moving it down will
cause the teeth to stand up more straight (more aggressive).
* Typically, the section should be set more aggressive for increased soil leveling and less aggressive in
heavy residue conditions. In some situations that do not require the extra leveling of the harrow section,
such as heavy fall residue, the sections can be removed.
Figure 5
Reversing the harrow sections and pulling them from the opposite end can change the angle of attack.
The steeper the angle of attack, the more aggressive the harrowing will be. It is recommended the least
aggressive angle be used with the pull hook in the top position as shown.
