  • Patent number: 6688243
    Abstract: A minimum tillage agricultural implement 10 having a plurality of laterally spaced shank assemblies 60, 62 mounted on a transverse tool bar 56, 58. Each shank assembly 60, 62 has an elongated narrow upright shank 70 that extends downward from the tool bar 56, 58 to a working point 78 for forming a narrow furrow 12 in soil covered with agricultural residue. Each shank assembly 60, 62 has a set of residue control wheels 130, 132 that straddle the shank 70 with the axes 134, 136 of rotation of the residue control wheels 130, 132 being located rearward of a front edge reference segment 82 of the shank 70 by a distance “A” of less than a diameter of the wheels 130 or 132 for engaging and stabilizing the soil and agricultural residue downward and under the wheels and away from the shank 70. In an alternate embodiment, the residue control wheels 130, 132 are longitudinally offset with the distance “B” between the axes 134 and 136 are less than one-third the diameter of the wheels 130, 132.
