I just bought a Model W Letourneau scraper, looks like it is in decent shape. I am converting it over to hydraulics to use behind my four wheel drive tractor. These old beast are interesting, and am looking for some more info on them. I measured it to about 20 yards or so, but not sure on the manufacturer rating. Does anyone know when these were built? It is a serial # WE, so i found out that it is one of the last ones built, maybe around 1950? I will post some pics too so you can take a closer look. I think this one was used for stripping overburden from a coal mine.
