Abstract
A barn cleaner for scraping manure from an alley between two rows of open stalls for cows, which cleaner includes a scraper element which extends transversely of the alley and is of generally triangular cross-section with the base of the triangle against the surface to be scraped to present rearwardly inclining scraping surfaces in both directions. The triangular scraper element includes weight means within the triangular area to insure intimate scraping contact. In a modification a pair of longitudinally spaced transversely extending scrapers are connected at their opposite ends by guide plates which extend longitudinally of the alley and form a rigid rectangular scraping frame with the guide plates in sliding engagement with curb formations at the juncture of the open stall spaces with the alley therebetween.
