A farm (also called an agricultural holding) is an area of land that is devoted primarily to agricultural processes with the primary objective of producing food and other crops; it is the basic facility in food production. The name is used fo ...

A windrow is a row of cut (mown) hay or small grain crop. It is allowed to dry before being baled, combined, or rolled. For hay, the windrow is often formed by a hay rake, which rakes hay that has been cut by a mowing machine or by scythe into a ...

scything, cradling and swathing, or

A mower is a person or machine that cuts (mows) grass or other plants that grow on the ground. Usually mowing is distinguished from reaping, which uses similar implements, but is the traditional term for harvesting grain crops, e.g. with reapers ...

A threshing machine or a thresher is a piece of farm equipment that threshes grain, that is, it removes the seeds from the stalks and husks. It does so by beating the plant to make the seeds fall out.

s, the swather introduced an optional step in the harvesting process to provide for the drying time that
binding formerly afforded. Swathing is still more common in the northern United States and Canada than regions with longer growing seasons where standing grain crops can be harvested directly by combines. Some modern crop varieties capable of rapid maturity have reduced the need for swathing grains even in the north.
As well as accelerating drying of the ripe grain, windrowing the whole of the growing crop provides for a consistent ripening and dehydration of stalk and green weeds to assist in effective post threshing winnowing and separation of the grain and other material.
