  • Crust fracturing implement
    Patent number: 7753133
    Abstract: An apparatus for fracturing a crust on an agricultural field includes a tool bar and a support attached to the tool bar. A plurality of discs are non-rotatably attached to an axle that is rotatably supported by the support. Each of the plurality of discs include a plurality of spaced apart teeth about the perimeter of each disc. The teeth comprise convex surfaces and concave surfaces that converge at distal ends where the plurality of discs rotate about the support such that the convex surfaces penetrate and fracture the crust and that any debris or trash picked up by the teeth is ejected by the angles of the teeth and angles of the support brackets preventing plugging and destruction of the rowed crop.
