A threshing machine or a thresher is a piece of farm equipment that separates grain seed from the stalks and husks. It does so by beating the plant to make the seeds fall out. Before such machines were developed, threshing was done by hand with flails: such hand threshing was very laborious and time-consuming, taking about one-quarter of agricultural labour by the 18th century. Mechanization of this process removed a substantial amount of drudgery from farm labour. The first threshing machine was invented circa 1786 by the Scottish engineer Andrew Meikle, and the subsequent adoption of such machines was one of the earlier examples of the mechanization of agriculture. During the 19th century, threshers and mechanical reapers and reaper-binders gradually became widespread and made grain production much less laborious.
A scythe is an agricultural hand tool for mowing grass or harvesting crops. It is historically used to cut down or reap edible grains, before the process of threshing. The scythe has been largely replaced by horse-drawn and then tractor machinery, but is still used in some areas of Europe and Asia. Reapers are bladed machines that automate the cutting of the scythe, and sometimes subsequent steps in preparing the grain or the straw or hay.
The modern combine harvester, also called a combine, is a machine designed to harvest a variety of cultivated seeds. Combine harvesters are one of the most economically important labour-saving inventions, significantly reducing the fraction of the population engaged in agriculture. Among the crops harvested with a combine are wheat, rice, oats, rye, barley, corn (maize), sorghum, millet, soybeans, flax (linseed), sunflowers and rapeseed. The separated straw is then either chopped onto the field and ploughed back in, or laid out in rows, ready to be baled and used for bedding and cattle feed.
A reaper is a farm implement or person that reaps crops at harvest when they are ripe. Usually the crop involved is a cereal grass. The first documented reaping machines were Gallic reapers that were used in Roman times in what would become modern-day France. The Gallic reaper involved a comb which collected the heads, with an operator knocking the grain into a box for later threshing.
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 and combines.
A baler or hay baler is a piece of farm machinery used to compress a cut and raked crop into compact bales that are easy to handle, transport, and store. Often, bales are configured to dry and preserve some intrinsic value of the plants bundled. Different types of balers are commonly used, each producing a different type of bale – rectangular or cylindrical, of various sizes, bound with twine, strapping, netting, or wire.
Threshing or thrashing is the process of loosening the edible part of grain from the straw to which it is attached. It is the step in grain preparation after reaping. Threshing does not remove the bran from the grain.
A swather, or windrower, is a farm implement that cuts hay or small grain crops and forms them into a windrow for drying.
Mechanised agriculture or agricultural mechanization is the use of machinery and equipment, ranging from simple and basic hand tools to more sophisticated, motorized equipment and machinery, to perform agricultural operations. In modern times, powered machinery has replaced many farm task formerly carried out by manual labour or by working animals such as oxen, horses and mules.
William Deering was an American businessman and philanthropist. He inherited a woolen mill in Maine, but made his fortune in later life with the Deering Harvester Company.
A steam tractor is a tractor powered by a steam engine which is used for pulling.
A stook /stʊk/, also referred to as a shock or stack, is an arrangement of sheaves of cut grain-stalks placed so as to keep the grain-heads off the ground while still in the field and before collection for threshing. Stooked grain sheaves are typically wheat, barley and oats. In the era before combine harvesters and powered grain driers, stooking was necessary to dry the grain for a period of days to weeks before threshing, to achieve a moisture level low enough for storage. In the 21st century, most grain is produced with the mechanized and powered methods, and is therefore not stooked at all. However, stooking remains useful to smallholders who grow their own grain, or at least some of it, as opposed to buying it.
Daniel Best was an American adventurer, businessman, farmer, and inventor known for pioneering agriculture machinery and heavy machinery.
A grain cradle or cradle, is a modification to a standard scythe to keep the cut grain stems aligned. The cradle scythe has an additional arrangement of fingers attached to the snaith to catch the cut grain so that it can be cleanly laid down in a row with the grain heads aligned for collection and efficient threshing.
John Francis Appleby (1840–1917) was an American inventor who developed a knotting device to bind grain bundles with twine. It became the foundation for all farm grain binding machinery and was used extensively by all the major manufacturers of large grain harvesting machines in the late 19th and early 20th centuries. Appleby's knotting device was a major landmark in the mechanization of agriculture and aided the development of the western wheat fields of the United States.
Agricultural machinery relates to the mechanical structures and devices used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the farm implements that they tow or operate. Machinery is used in both organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed.
The McCormick–International Harvester Company Branch House was built in 1898 in Madison, Wisconsin as a distribution center for farm implements of the McCormick Harvesting Machine Company. After McCormick merged into the International Harvester Company in 1902, the building was expanded and served the same function for the new company. In 2010 it was added to the National Register of Historic Places.
A sheaf is a bunch of cereal-crop stems bound together after reaping, traditionally by sickle, later by scythe or, after its introduction in 1872, by a mechanical reaper-binder.
Stripper was a type of harvesting machine common in Australia in the late 19th and early 20th century. John Ridley is now accepted as its inventor, though John Wrathall Bull argued strongly for the credit.
