ABSTRACT:
A clamp for mounting an agricultural spring tooth to a square cross section tool bar includes an L-shaped angle bracket, one leg having a transverse slot near a free end thereof, the other leg having a bolt receiving aperture near its end, and a partially channel shaped retaining clip having a transverse slot near one end and a bolt receiving aperture near the other end. The bracket is mounted on the tool bar in contact with two adjacent sides of the square bar, the mounting of the spring tooth shank being received in the bracket slot and contacting another side of the bar, and the clip being overlayed on the mounting shank with the end of the one leg received in the clip slot. A bolt is passed through the other leg, the clip, and the shank, clamping same together on the tool bar. Side flanges on the retaining clip rest adjacent side edges of the mounting shank whereby, in cooperation with the clip slot, lateral pivoting of the tooth is resisted.
