CULTIVATOR TOOL SHANK ASSEMBLY Abstract of the Disclosure This invention relates to a cultivating shank assembly in which a mounting frame is comprised of a mounting frame portion and a tool shank support portion pivoted thereon. The mounting frame portion and the tool support portion are formed of plates which are held together by suitable transversely extending plates which support the mounting frame on a cultivating tool bar and mount the tool shank respectively. A compression spring for the mounting assembly is connected between the tool shank portion and the mounting frame portion of the mounting frame and is guided between inner and outer cylindrical spring retainers which are pivoted respect- ively on the tool shank support portion and the mounting frame portion to prevent the compression spring from buckling and to guide the same such that the compressive force will always be applied along the extent of the spring. Suitable apertures in the mounting frame portion provide a limit stop to define the pitch adjustment of the tool shank and provide preload adjustment for the compression spring.
