Abstract
Disclosed are two types of track sections respectively having link assemblies interconnected by pivot joints and by resilient flexors. In both types of track sections a sprocket-engaging portion is provided for being engaged by teeth of a track drive sprocket, and a receptacle-cleaning portion is provided for entering receptacles defined by adjacent ones of the sprocket teeth and includes beveled or wedge-shaped ribs for forcing material from the receptacles. The sprocket-engaging portions of adjacent track sections are spaced apart by a distance at least approximating twice the pitch of the sprocket whereby an unused receptacle exists between each adjacent pair of sprocket-engaging portions which is meshed with the sprocket, and the receptacle-cleaning portions are located so as to enter the unused receptacles.
