Massey-Harris self-propelled combine put an end to threshing.
This 1945 Massey-Harris 21A combine features the unit’s original lampshade-like Air-Brella. “It has a fan to blow away the chaff,” Steve Weeber notes. “I would highly question how well that would work. Maybe it’d work on a windy day, but otherwise I think it’d blow chaff right down your collar.” Because the combine was to be used for custom work, Steve’s father, Woody Weeber, installed dual wheels. “That was way ahead of its time for farm implements,” Steve says.
A photo from the April 1944 issue of Farm Machinery and Equipment magazine shows a trainload of Massey-Harris self-propelled combines “On their Way to the Farm Front.”
