Shank-mounted press wheel assembly
First Claim
1. In an implement having a shank-supported tool adapted for forward movement through the soil, a shank-mounted press wheel assembly adapted for connecting a fore-and-aft extending press wheel arm to the shank, the assembly comprising:
- a bracket body having an upright central portion adapted for positioning against the aft face of the shank, an upper end portion connected to the upper end of the central portion and including forwardly projecting and transversely spaced ears adapted for positioning closely adjacent the sides of the shank, a lower end portion connected to the lower end of the central portion and including a rearwardly projecting transversely apertured pivot area closely adjacent the aft face of the shank, and a leg extending rearwardly from the upper end portion;
means pivotally connecting the press wheel arm to the pivot area for rocking vertically with respect to the bracket body;
a down-pressure spring;
means for supporting the down-pressure spring between the leg and the press wheel arm; and
clamp means for selectively securing the body to the aft face and permitting adjustment of the body vertically along the length of the shank.

Abstract
A shank-mounted press wheel assembly includes a main shank bracket cast as a unitary structure and adapted for securing against the aft face of a shank by a single U-bolt. The cast structure includes an integral transverse pivot for mounting a fore-and-aft extending press wheel drawbar and a rearwardly extending leg for receiving the upper end of a tension link supporting a compression spring for providing adjustable down-pressure on the press wheel. Vertical adjustments of the press wheel assembly may be made quickly and conveniently by simply loosening two nuts on the U-bolt which secures the bracket to the shank. Angular travel stops for the drawbar are provided by a locknut on the tension link and by the solid compressed length of the coil spring. An adjustable wheel support located on the aft end of the drawbar permits the press wheel center line to be adjusted with respect to the tool shank center line.
