ABSTRACT OF THE DISCLOSURE This invention relates to a wear-parts system for earth-moving machines such as digger, loading, and mining machines. This wear-parts sy- stem consists of a holder and at least one protruding wear-part in the form of a tooth or the like fixed on the front of the holder by means of a wedge or other locking device. According to the invention the wear-part lands directly against the holder within a forward and a rear landing area in which a landing free from play within the forward landing area is achieved by means of a wedging effect between the wear-part and the holder when the wear-part is pressed or drawn backwards into the holder, while a landing free from play is achieved between both these parts within the rear landing area by means of the locking device pressing two mutually angled landing surfaces on the rear of the wear-part against two opposite equivalently angled landing surfaces in the holder.
