That is a really good video, crayton. For their time, those old machines were quite large capacity. What brand of engines drive the harvesters and were they petrol/kerosine or diesel? There were what we called engine functioned harvesters here, that had Hercules petrol/kerosine engines driving them. They were originally pulled by horses and later by tractors, then they were phased out by harvesters driven by the pto shaft from the tractor. I never saw or heard of those type of harvesters in the video, come in to Australia and the machines here were quite a bit smaller. The following pic is not real good quality, but it gives you the general idea. This machine is a Sunshine No. 6, engine functioned harvester. Here it has a smaller pickup on it for harvesting ryegrass seed, normally it would probably have a 10 foot comb for grain.
