Harrow Modules
Harrow Module Harrow Modules provide additional surface tillage for breaking the crust, breaking clods, smoothing, leveling, preparing seed beds and many other applications. They provide tillage in heavy residue conditions in which rolling crumblers and choppers are not effective.
Key Features 
  • With the universal mount that is provided the Harrow Module Attachment can attach to 4, 5, 6, 7, and 8 inch tool bars.
  • Parallel linkages provide a quick adjustment to level the module tool bar from left to right, provide for vertical adjustment and for leveling the pitch of the rear tool bar to which harrow modules are attached.
  • Single bolt adjustment provides for modules to be easily adjusted incrementally on 0, 15, 25, and 35 degree angles in order to vary the aggressiveness of this tool.
  • Harrow modules can be reversed from end to end to run in the aggressive direction or the standard direction.
