What do you mean by grain drying?

Threshing, also called "threshing", is a series of activities called threshing to build a flat land between wheat fields to thresh or dry wheat. The harvested grains with shells are spread out in the yard and crushed by horses or small tractors to remove the shells.

The process of threshing the harvested grain in the yard is called threshing.

In today's rural areas, threshing has mostly been replaced by threshing machines.
