An agricultural shank assembly includes an edge-bent standard having an integral tool-receiving end which is tapered to provide a self-locking fit for a matching sweep. A non-corroding plastic pin inserted through a hole in the sweep and through an elongate hole in the end of the standard retains the sweep in position and prevents the sweep from jarring loose. The elongate hole in the standard accommodates considerable variation in the tapered end and the mating sweep portion. The pin is easily shearable by a hammer blow to the sweep during sweep replacement.
