  • Mill the Weed Seed in Grain Combines
    Publication number: 20210144918
    Abstract: My invention to “Mill the Weed Seed from Grain Combines” will kill much of the weed seed that would have been available the next year by milling (grinding) it. Mainly, this will reduce the weed seed and secondarily it could also reduce the volume of poisonous chemical herbicides that will be needed to control weeds in crops.
