The threshing machine is surely the greatest single advance in the mechanisation of agriculture. The huge reduction in manpower it produced led to rioting and its unpopularity also slowed down the early development of the steam engine.
Because of the lack of literature on the subject, this book aims to treat the subject of threshing as a whole. As well as detailed analysis of threshing machine development, design and construction, plus a survey of its builders, this book also looks at the associated ancillary equipment and reviews the sources of motive power used. To complete the picture, there is a brief look at the background history and the thresher's eventual metamorphosis into the combine harvester.
The traction engine, and the portable engine before it, only came into existence to power the threshing machine. This book hopes to go some way to the threshing machine in its rightful place.
