1. In an agricultural planting machine having a frame, a pair of opposite furrow forming disks rotatably mounted on the frame on intersecting axes so that the disks diverge upwardly from a point of contact below the axes of the disks, and a pair of gauge wheel assemblies mounted on the frame respectively adjacent the opposite sides of the pair of furrow forming disks, each gauge wheel assembly including a gauge wheel journaled on one end of an arm for rotation about an axis rearwardly of and generally parallel to the axis of the adjacent disk, an improved means for adjustably mounting the other end of each gauge wheel arm to the frame and comprising:

  • a cylindrical shaft mounted on the frame and having an axis generally parallel to the axis of the gauge wheel;

    an externally threaded bushing rotatably mounted on the shaft;

    an internally threaded bore in said other end of the arm and threadably mounted on the bushing so that rotation of the bushing on the shaft moves the arm in an axial direction relative to the shaft to adjust the lateral spacing of the gauge wheel from the adjacent disk; and

    locking means for selectively locking the bushing to the shaft to prevent rotation of the bushing.
