I was just about to post the above link to Vince Falter's page regarding these engines used on grain Combines. For anyone wondering, Binders were pre-combine machines pulled by either a team of horses or a small tractor and used to cut and tie the grain into bunches which were then pitched into a threshing machine to separate the grain from the straw. The Combine combined these two operations making for a much less labour intensive operation.
