Minimum tillage ripper point with fin

A deep tillage point adapted for connection to a shank for forward movement through the soil, the point comprising:

• a leading point portion that forms a forward point angle greater than approximately 40 degrees with the horizontal, an intermediate portion extending rearwardly from the leading point portion and supporting laterally extending wings having leading wing edges, 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 extending upwardly and rearwardly from the leading point portion and having a forwardmost portion located forwardly of the leading wing edges, the upright fin 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 he wings.

A deep tillage point adapted for connection to a shank for forward movement through the soil, the point comprising:

• an elongated leading point portion angled downwardly in the forward direction, an intermediate portion angled rearwardly from the leading point portion, wings extending laterally from the intermediate portion and having leading wing edges, the wings defining an attack angle of less than approximately 20 degrees to the horizontal to limit upward movement of the soil, and a centrally located upright fin extending upwardly and rearwardly from the leading point portion, the fin having a forward portion offset forwardly of the leading wing edges directly above the leading point portion, and wherein upright fin imparts substantial lateral movement of the soil prior to contact of the soil by the leading wing edges and limits violent vertical eruption of the soil when contacted by the wings.
