  • Combination farming implement
    Patent number: 11570942
    Abstract: A cultivator function is coupled with a scraper function in a single implement such that the cultivator portion and the scraper portion of the combination farming implement, when attached to a vehicle, can be mechanically and remotely changed out at any time. The cultivator portion and the scraper portion of the combination farming implement are positioned on opposite sides of a rotating framework, such that the combination farming implement can be mechanically and remotely rotated during use in the field, thus enabling the performance of both the cultivator function and the scraper function without a vehicle operator ever leaving the vehicle.
