Power Take Off
A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine. Most commonly, it is a splined drive shaft installed on a tractor or truck allowing implements with mating fittings to be powered directly by the engine. Semi-permanently mounted power take-offs can also be found on industrial and marine engines. These applications typically use a drive shaft and bolted joint to transmit power to a secondary implement or accessory. In the case of a marine application, such shafts may be used to power fire pumps. In aircraft applications, such an accessory drive may be used in conjunction with a constant speed drive. Jet aircraft have four types of PTO units: internal gearbox, external gearbox, radial drive shaft, and bleed air, which are used to power engine accessories. In some cases, aircraft power take-off systems also prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traction Engine
A traction engine is a steam engine, 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 steam locomotive, locomotives – that is, steam engines that run on rails. Traction engines tend to be large, robust and powerful, but also heavy, slow, and difficult to manoeuvre. Nevertheless, they revolutionized agriculture and road haulage at a time when the only alternative Prime mover (tractor unit), prime mover was the draught horse. They became popular in industrialised countries from around 1850, when the first self-propelled portable steam engines for agricultural use were developed. Production continued well into the early part of the 20th century, when competition from internal combustion engine-powered ...

Brantford
Brantford ( 2021 population: 104,688) is a city in Ontario, Canada, founded on the Grand River in Southwestern Ontario. It is surrounded by Brant County, but is politically separate with a municipal government of its own that is fully independent of the county's municipal government. Brantford is situated on the Haldimand Tract, traditional territory of the Neutral, Mississauga, and Haudenosaunee peoples. The city is named after Joseph Brant, an important Mohawk leader, soldier, farmer and slave owner. Brant was an important Loyalist leader during the American Revolutionary War and later, after the Haudenosaunee moved to the Brantford area in Upper Canada. Many of his descendants, and other First Nations people, live on the nearby Six Nations of the Grand River reserve south of Brantford; it is the most populous reserve in Canada. Brantford is known as the "Telephone City" as the city's famous resident, Alexander Graham Bell, invented the first telephone at his father's ...

Cockshutt Plow Company
Cockshutt was a large agricultural machinery manufacturer, known as Cockshutt Farm Equipment Limited (1957–1962), based in Brantford, Ontario, Canada. Founded as the Brantford Plow Works by James G. Cockshutt in 1877, the name was changed to the Cockshutt Plow Company when it was incorporated in 1882. After James died shortly thereafter, his brother William Foster Cockshutt took over as president. He remained until 1888, when another brother, Frank Cockshutt, became president of the company. In 1910, Henry Cockshutt, the youngest of the brothers, took over the leadership of the company. Under his direction, the company was able to obtain financing for acquisitions and expansion. History Known for quality designs, the company became the leader in the tillage tools sector by the 1920s. Since Cockshutt did not have a tractor design of its own yet, in 1929 an arrangement was made to distribute Allis-Chalmers model 20-35 and United tractors (United was a group of Fordson deal ...

Manure Spreader
A manure spreader or muck spreader or honey wagon is an agricultural machine used to distribute manure over a field as a fertilizer. A typical (modern) manure spreader consists of a trailer towed behind a tractor with a rotating mechanism driven by the tractor's power take off (PTO). Truck mounted manure spreaders are also common in North America. Operation Manure spreaders began as ground-driven units which could be pulled by a horse or team of horses. Many of these ground-driven spreaders are still produced today, mostly in the form of small units that can be pulled behind a larger garden tractor or an all terrain vehicle (ATV). In recent years hydraulic and PTO driven units have been developed to offer variable application rates. Several models are also designed with removable rotating mechanisms (beaters), attachable side extensions, and tailgates for hauling chopped forages, cereal grains, and other crops. A typical (modern) manure spreader consists of a trailer towed be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Speed
Ground speed is the horizontal speed of an aircraft relative to the Earth’s surface. It is vital for accurate navigation that the pilot has an estimate of the ground speed that will be achieved during each leg of a flight. An aircraft diving vertically would have a ground speed of zero. Information displayed to passengers through the entertainment system of airline aircraft usually gives the aircraft ground speed rather than airspeed. Ground speed can be determined by the vector sum of the aircraft's true airspeed and the current wind speed and direction; a headwind subtracts from the ground speed, while a tailwind adds to it. Winds at other angles to the heading will have components of either headwind or tailwind as well as a crosswind component. An airspeed indicator indicates the aircraft's speed relative to the air mass. The air mass may be moving over the ground due to wind, and therefore some additional means to provide position over the ground is required. This might ...

Gear Train
A gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. Features of gears and gear trains include: * The gear ratio of the pitch circles of mating gears defines the speed ratio and the mechanical advantage of the gear set. * A planetary gear train provides high gear reduction in a compact package. * It is possible to design gear teeth for gears that are non-circular, yet still transmit torque smoothly. * The speed ratios of chain and belt drives are computed in the same way as gear ratios. See bicycle gearing. The transmission of rotation between contacting toothed wheels can be traced back to the Antikythera mechanism of Greece and the south-pointing chariot of China. Illustrations by the Renaissance scientist Georgius Agricola show gear trains wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tractor
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) 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 (and originally) 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. Etymology The word ''tractor'' was taken from Latin, being the agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term " traction motor" (1859). National variations In the UK, Ireland, Australia, India, Spain, Argentina, Slovenia, Serbia, Croatia, the Netherlands, and Germany, the word "tracto ...

Case Corporation
The Case Corporation was a manufacturer of agricultural machinery and construction equipment. Founded, in 1842, by Jerome Increase Case as the J. I. Case Threshing Machine Company, it operated under that name for most of a century. For another 66 years it was the J. I. Case Company, and was often called simply Case. In the late 19th century, Case was one of America's largest builders of steam engines, producing self-propelled portable engines, traction engines and steam tractors. It was a major producer of threshing machines and other harvesting equipment. The company also produced various machinery for the U.S. military (combat engineer equipment for the USMC, full-tracked tractors and scoop loaders for the U.S. Army, etc.). In the 20th century, Case was among the ten largest builders of farm tractors for many years. In the 1950s its construction equipment line became its primary focus, with agricultural business second. Case's corporate entities and brands change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Harvester
The International Harvester Company (often abbreviated by IHC, IH, or simply International ( colloq.)) was an American manufacturer of agricultural and construction equipment, automobiles, commercial trucks, lawn and garden products, household equipment, and more. It was formed from the 1902 merger of McCormick Harvesting Machine Company and Deering Harvester Company and three smaller manufactures: Milwaukee; Plano; and Warder, Bushnell, and Glessner (manufacturers of Champion brand). In the 1980s all divisions were sold off except for International Trucks, which changed its parent company name to Navistar International (NYSE: NAV). Its brands included McCormick, Deering, and later McCormick-Deering, as well as International. Along with the Farmall and Cub Cadet tractors, International was also known for the Scout and Travelall vehicle nameplates. Given its monumental importance to the building of rural communities the brand continues to have a massive cult following. The ...
