ABSTRACT:
An ejector roller and guide arrangement having a pair of rollers beveled on their outer edges, one on each side of the ejector frame, which travel between horizontal upper and lower tracks mounted on the pusher frame. The beveled edges of the rollers ride on inwardly angled surfaces of the track.

The longitudinally spaced rollers provide lateral and vertical guidance of the ejector in moving into and out of the scraper bowl for ejection of the earth material.
