Purpose and Scope

The purpose of this Standard is to provide greater interchangeability of cultivator sweeps, shovels, and points used on various types of footpieces for row crop cultivators, field cultivators, chisel plows and rippers; to provide a good fit and thereby better mechanical support for sweeps, shovels and points on such footpieces; and to provide ground clearance between the lowest portion of footpieces or attaching bolts and the cutting edge of sweeps to accommodate wear.

This Standard includes the following specifications for row crop cultivators, field cultivators, chisel plows and rippers:

Mounting specifications for the ground tool attaching portion of the shank as applied to spring trip and friction trip shanks, stiff shanks and square coil spring tool shanks, and flat spring tooth shanks.

Attaching specifications for sweeps with curved stems; double pointed shovels, teeth and spikes; and spear point and single end shovels; and ripper shank points.
