Threshing machine; Frank Cowan Threshing machine shots- the era of owning threshing machine, driving it with a tractor, before combines. Notes from Don Beatty and John Cowan talking on the tape. "What do you have on this, Frank? My son, Andrew Cowan, is pitching off. I think it is possibly the last time we threshed at the barn bridge with the separator in the barn and the unloading right at the barn door. I think this was especially taken; one of the last picture you could find of that kind of threshing. I thought it was a little modern because of the height of the wagon. That wagon was converted to rubber by that time? Yes, that was a high wagon at one time; a high wagon cut down and rubber put on. What kind of power did you have? Were you threshing with the W4? It was an Alis Chalmers. where is that separator now; is it still around? Yes, that separator is still behind the driving shed at home. I wish someone would take it for the taking.
