Abstract:
A deep tillage point adapted for connection to a shank for forward movement through the soil, the point comprising: a leading point portion with a front edge and a top surface that forms a forward point angle in the range of approximately 40-50 degrees with the horizontal, an intermediate portion extending rearwardly from the leading point portion and including a top surface, wings having leading and trailing edges and extending laterally from the top surface, the wings defining a relatively shallow wing angle of less than approximately 20 degrees to the horizontal to limit upward movement of the soil, and a centrally located upright fin having a width less than the width of the leading point portion, the fin extending upwardly from the leading point portion at a location adjacent the front edge and forwardly of the leading edges of the wings and imparting substantial lateral movement of the soil prior to contact of the soil by the wings and limiting violent vertical eruption of the soil when contacted by the wings.
