We all know that a threshing machine threshes the freshly cut cereal crop, but exactly how does it do it? Seeing a threshing machine working at a rally or agricultural show, there is clearly a lot going on inside the box, but what exactly?
This book not only explains the processes simply, but gives the history of threshing from ancient times, describes the cereals etc. that are threshed, and the development of the threshing machine, surveys the makers, describes the ‘motive power’ and so on. The author ends with Combine Harvesters, and makes the point that, inside them, are all the components of a threshing drum.
250 pages, very well illustrated with drawings, photos, most in colour, and numerous diagrams. Hardbound.
