The Northeast Mechanical Weed Control Expo will feature tool demonstrations and research results for both vegetable and grain production. Hand-tools, walk-behind tractors/tool carriers, and tractor-mounted equipment will be on display and demonstrated in the field, and will include equipment from Terrateck® and Johnny’s Selected Seeds, HAK®, Tilmor®, K.U.L.T.-Kress®, Garford®, Treffler® Harrows, and Franklin Robotics.  We invite farmers of all levels of experience and production to participate. The day will include:

  • Research presentations and posters
  • Field demonstrations of tools for small-, mid- and large-scale growers
  • Friendly competition testing your weed knowledge and cultivation skills!
  • Plenty of time to connect with fellow growers, researchers, and industry representatives

The Northeast Mechanical Weed Control Expo is supported by grants from the USDA-NIFA Organic Agriculture Research and Extension Initiative (OREI) and the Northeastern IPM Center.

    Including the Terrateck Double Wheel Hoe
  • Station 2: Newest stacked tool parallel linkages — Michael Smith, KULT Kress
    Belly-mounted Next Gen units and rear-mounted Duo units
  • Station 3: Steketee weeders — Joseph Sutton, Sutton Ag
    Including finger and brush weeders
  • Station 4: Camera-guided cultivation for field crops — Tom Molloy, UMaine
    Using a robotic side-shift unit and inter-row hoes
  • Station 5: What’s new at Tilmor — Ben Baltzly and Doug Zehr, Tilmor
