Answer:

THRESHING:The process of separating the grain from cut crop is called threshing. It can be done by using  animals like Oxen and buffaloes or by using machines called threshers or combines. Combines are  used both for harvesting and threshing.

HARVESTING: Harvesting is the process of gathering a ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season.

WINNOWING: The process of separating the grain from the chaff manually by the action of wind is called  winnowing. In this process the mixture is dropped on the ground from a height. The heavier seeds  fall almost vertically down, where as the lighter chaff gets blown away by the wind and falls at a distance.
