Period

This combine was used between 1976 and 1988.

Canada

The Roto Thresh combine was developed, manufactured, and used in Canada. Manitoba farmers Bill & Fred Streich, with the help of Frank McBain and Barney Habicht, developed and produced the first prototype in 1951. They went on to form the Western Roto Thresh Manufacturing Company in 1968 and produced a more advanced prototype in collaboration with the University of Saskachewan. Roto Thresh began production in 1974, but only fifty machines were manufactured before the company closed in 1978. When the patents expired, large manufacturers such as John Deere adopted and perfected the centrifugal aspirating technology, which is found today on many different combine models.

Function

The combine harvester, also known earlier as the reaper-thresher, combines in one machine all the operations associated with cereal-grain harvesting: reaping, gathering, threshing, sorting and winnowing. First conceived in the late 19th century, combine harvesters became popular the 20th century as grain farming expanded, particularly in western North America. Combine harvesters came in towed and self-propelled models, with self-propelled models dominating production after the 1940s.

Technical

The Roto Thresh was the first combine to use a rotary system to separate grain from chaff using centrifugal force, a technological innovation still used in combine design today. The rotating cylinder was mounted perpendicular to the header and blew the chaff upwards. The Roto Thresh claimed to reduce grain loss and harvest 250 to 300 bushels per hour.
