It took many people to thrash grain. Most of the work was done pitch forks. The pile in the rear is the straw blown out from the thrashing machine after the grain has been separated.
A belt is running from the tractor to the threshing machine. Two men are on the stack of bundles pitching the bundles into the threshing machine. The threshing machine separates the grain from the straw. Along side it two horses are hooked up to a wagon. Two women came to bring lunch.
