Abstract:
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 journalled on one end of a gauge wheel arm for rotation about an axis rearwardly of and generally parallel to the axis of the adjacent disks, an improved means for adjustably mounting the other end of each gauge wheel arm which has an internally threaded bore to the frame and comprising: an internally threaded 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 for engagement with the internally threaded bore in the gauge wheel arm; rotation of the bushing with respect to the gauge wheel arm moving the gauge wheel arm axially of the internally threaded cylindrical shaft to adjust the lateral spacing of the gauge wheel from the adjacent disk; a locking member locking the externally threaded bushing to the other end of the gauge wheel arm to cause rotation of the bushing and the arm as a unit; a connector having an externally threaded shank and a head, said shank extending through said bushing and the internally threaded bore in the gauge wheel arm into said internally threaded shaft to mount the gauge wheel arm to the shaft and the frame; axial adjustment of the gauge wheel arm relative to the furrow forming disks being provided by movement of said locking member relative to said externally threaded bushing; and at least one spacer between the end of the internally threaded shaft and the head of the externally threaded connector to accommodate variations in the length of the shaft.
