Sometimes hobby and business interfere unexpectedly. Volkswagen used to collaborate with many different other manufacturers. The beetle chassis for instance, was supplied to numerous coach builders including Beutler, Rometsch and Karmann. For industrial use, VW offered its aircooled boxer engine in a stationary version. This stationairy engine distinguishes itself with a different distributor and different flywheel.

Unknown to me was the history of the Claas Huckepack carrier whose first prototype featured a chassis of the Volkswagen Transporter. It also had a threshing unit that was propelled by a 34 bhp VW stationairy engine! The article below is taken from the Belgian magazine ´De Loonwerker´.
