ABSTRACT:
A replaceable blade yoke holder, carried by an adapter clamp, comprising a pair of parallel horizontal wedges, with the wedges adapted to be removably held together by bolt holding means, and with certain of adjacent outer edges of the wedges being adapted for replaceably holding a cultivator blade tool there upon bolt holding securement of the wedge together and with an edge of one of the wedges being reinforced with a carbon steel member secured at a ninety degree angle thereto to resist a bending of that wedge upon such bolt holding means securement of the wedges together.
This invention relates to replaceable blades in the farming industry, and more particularly to the type of a cultivator blade which is drawn through the ground a short distance below the surface of the ground. Such a blade usually has a point, and a cutting edge to cut the ground at a required depth. Use of the blade over a comparatively short period of time results in a dulling of the blade and requires that it be replaced. Therefore, the blade is carried in a replaceable manner by a suitable carrier.
