Threshing stone
A threshing stone is a roller-like tool used for the threshing of wheat. Similar to the use of threshing boards, the stone was pulled by horses over a circular pile of harvested wheat on a hardened dirt surface (threshing floor), and the rolling stone knocked the grain from the head of wheat.

A threshing stone is a roller-like tool used for the threshing of wheat. Similar to the use of threshing boards, the stone was pulled by horses over a circular pile of harvested wheat on a hardened dirt surface (threshing floor), and the rolling stone knocked the grain from the head of wheat. The straw was removed from the pile and the remaining grain and chaff was collected. By a process called winnowing, the grain was tossed into the air to allow the chaff and dirt to be blown away, leaving only the grain.
