Threshing at the Central Experimental Farm, former Caldwell farm, 1930s or 1940s.

In 1932, the J.E. Caldwell farm (300 plus acres) was leased by the CEF (and purchased in 1946).

This photograph shows a threshing gang working in the Caldwell field. The thresher is powered by the fly wheel on the tractor (left) and the sheaves are fed into the thresher (centre) to have the grain separated from the chaff. The chaff is blown out the long tubing to the ground behind the machinery. The man at the side of the machine is bagging the grain as it is separated and then loading it on the truck.
