ABSTRACT:
A corner tooth assembly is provided on the corner of an implement for protection thereof from wear during use. It is necessary to provide a tight fit between the corner tooth and the corner portion of the implement so that unnecessary movement of the corner tooth on the corner portion is avoided while at the same time not subjecting the corner tooth to undue stresses during initial installation of the corner tooth on the implement. The present corner tooth assembly includes a corner portion integrally connected to the implement with first and second load transferring pads defined on a leading edge thereof and first and second holes defined therein and a corner tooth adapted for releasable connection to the corner portion. A trailing end portion of the corner tooth has a load transferring portion including first and second load transferring surfaces adapted when installed to mate with the first and second load transferring pads of the corner portion and a single upright side portion with first and second holes therein operative when assembled to mate with respective first and second holes of the corner portion on an implement. By having the first and second load transferring surfaces mate with the first and second load transferring pads of the corner portion and the corner tooth being secured to the corner portion by a biasing means, a tight connection is made between the corner tooth and the corner portion.
