Spring loaded field cultivator tool support

摘要

A mounting apparatus for pivotally attaching a cultivator tool to a frame member of mobile farm equipment comprising an upright support bracket, an extension spring, and a tool holder member which is pivoted with respect to the bracket. The tool holder member has a web portion and side flange portions. Near the shank receiving end of the tool holder member the flange portions are folded under the shank to form a shank receiving socket which snugly holds the shank and prevents transverse movement thereof relative to the holder member. The spring is also pivotally attached by a connector member to the holder member. The tool holder member includes a cutout portion in the web thereof such that a pair of rims are formed which extend inwardly from the flanges. The connector member includes a sleeve extending between the flanges and having a pair of external cylindrical surfaces near each end thereof which engage the rims of the tool holder member. The sleeve also includes a central bore which is coaxial with the cylindrical surfaces thereof and which receives a pivot pin secured in coaxial apertures in the side flanges of the tool holder.
