Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower, which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking.
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.
Deere & Company, doing business as John Deere, is an American corporation that manufactures agricultural machinery, heavy equipment, forestry machinery, diesel engines, drivetrains used in heavy equipment, and lawn care equipment. It also provides financial services and other related activities.
A traction engine is a steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin tractus, meaning 'drawn', since the prime function of any traction engine is to draw a load behind it. They are sometimes called road locomotives to distinguish them from railway locomotives – that is, steam engines that run on rails.
The three-point hitch is a widely used type of hitch for attaching ploughs and other implements to an agricultural or industrial tractor. The three points resemble either a triangle, or the letter A. In engineering terms, three-point attachment is the simplest and the only statically determinate way of rigidly joining two bodies.
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.
A dynamometer or "dyno" for short, is a device for simultaneously measuring the torque and rotational speed (RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp.
Fordson was a brand name of tractors and trucks. It was used on a range of mass-produced general-purpose tractors manufactured by Henry Ford & Son Inc from 1917 to 1920, by Ford Motor Company (U.S.) and Ford Motor Company Ltd (U.K.) from 1920 to 1928, and by Ford Motor Company Ltd (U.K.) from 1929 to 1964. The latter also later built trucks and vans under the Fordson brand.
Carting is a dog sport or activity in which a dog pulls a dogcart filled with supplies, such as farm goods, camping equipment, groceries or firewood, but sometimes pulling people. Carting as a sport is also known as dryland mushing and is practiced all around the world, often to keep winter sled dogs in competition form during the off-season.
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.
A steam tractor is a tractor powered by a steam engine which is used for pulling.
An ox, also known as a bullock, is a bovine, trained and used as a draft animal. Oxen are commonly castrated adult male cattle; castration inhibits testosterone and aggression, which makes the males docile and safer to work with. Cows or bulls may also be used in some areas.
Truck and tractor pulling, also known as power pulling, is a form of a motorsport competition in which antique or modified tractors pull a heavy drag or sled along an 11-meter-wide (35 ft), 100-meter-long (330 ft) track, with the winner being the tractor that pulls the drag the farthest. Tractor pulling is popular in certain areas of the United States, Mexico, Canada, Europe, Australia, Brazil, South Africa, Vietnam, India and New Zealand. The sport is known as the world's most powerful motorsport, due to the multi-engined modified tractor pullers.
A tractor unit, also known as a truck unit, lorry unit, power unit, prime mover, ten-wheeler, semi-tractor, semi-truck, semi-lorry, tractor cab, truck cab, lorry cab, big rig tractor, big rig truck or big rig lorry or simply a tractor, truck, lorry, semi, big rig or rig, is a characteristically heavy-duty towing engine that provides motive power for hauling a towed or trailered load. These fall into two categories: heavy- and medium-duty military and commercial rear-wheel-drive semi-tractors used for hauling semi-trailers, and very heavy-duty typically off-road-capable, often 6×6, military and commercial tractor units, including ballast tractors.
The Avery Company, founded by Robert Hanneman Avery, was an American farm tractor manufacturer famed for its undermounted engine which resembled a railroad engine more than a conventional farm steam engine. Avery founded the farm implement business after the Civil War. His company built a large line of products, including steam engines, beginning in 1891. The company started with a return flue design and later adapted the undermount style, including a bulldog design on the smokebox door. Their design was well received by farmers in central Illinois. They expanded their market nationwide and overseas until the 1920s, when they failed to innovate and the company faltered. They manufactured trucks for a period of time, and then automobiles. until they finally succumbed to an agricultural crisis and the Depression.
Draft horse showing refers to horse shows exclusively for horses of the draft horse breeds. In North America, though a small number of draft horses are also shown under saddle, the term "Draft horse showing" refers to a specific horse show competition that primarily features driving exhibitors presenting their horses to be judged in harness. Worldwide, some draft horse shows also feature riding classes.
The Trait du Nord, previously also known as Ardennais du Nord or Ardennais de type Nord, is a breed of heavy draft horse developed and bred in the area of Hainaut in western Belgium and in northeastern France. Originally considered a subtype of the Ardennes, it was recognized as an individual breed with the opening of a studbook in 1903. Developed in the fertile Flemish grasslands, it was bred for size and pulling power for agricultural work. By 1855, the horses bred near Hainaut were considered by some veterinarians to be superior to other Flemish draft breeds. The Trait du Nord was used extensively in mining from the late 19th century through 1920, with lesser use continuing through the 1960s.
Driving, when applied to horses, ponies, mules, or donkeys, is a broad term for hitching equines to a wagon, carriage, cart, sleigh, or other horse-drawn vehicle by means of a harness and working them in this way. It encompasses a wide range of activities from pleasure driving, to harness racing, to farm work, horse shows, and even international combined driving.
The Lester F. Larsen Tractor Test and Power Museum is a museum dedicated to preserving and documenting the history of Nebraska's tractor test law, operated by the University of Nebraska–Lincoln (NU) in Lincoln, Nebraska, United States. The Nebraska Tractor Test Law, passed in 1919 and administered by the university, requires performance testing on every tractor with forty horsepower or more sold in the state. The facility, initially established as the Nebraska Tractor Test Laboratory, was renamed for longtime chief engineer Lester F. Larsen when it was converted into a museum in 1998. It is the only tractor testing museum and the only complete tractor test laboratory in the world.
