Monowheel Tractor
A monowheel tractor or monowheel-drive tractor is a light transport and agricultural vehicle that is driven and controlled by an engine and steering mechanism mounted on a single large wheel, with the load-carrying body trailing behind. Despite the name, they are tricycles. Development Monowheel tractors developed in two periods, both during times of rapid upheaval after warfare. Both types had quite different circumstances and goals. Small wheel tractors appeared after World War I, during a time of new opportunity. Large-wheel tractors appeared after World War II, during a period of austerity. Small wheel tractors The first monowheel tractors appeared in the 1920s, as a result of technical developments in small petrol engines. These had been driven by improving engine technology, particularly for motorbikes. Such engines now represented an affordable and portable power source. An entire powertrain could be constructed as a single monobloc unit, carried on a single wheel, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classic Tractors (2620812423)
A classic is an outstanding example of a particular style; something of lasting worth or with a timeless quality; of the first or highest quality, class, or rank – something that exemplifies its class. The word can be an adjective (a ''classic'' car) or a noun (a ''classic'' of English literature). It denotes a particular quality in art, architecture, literature, design, technology, or other cultural artifacts. In commerce, products are named 'classic' to denote a long-standing popular version or model, to distinguish it from a newer variety. ''Classic'' is used to describe many major, long-standing sporting events. Colloquially, an everyday occurrence (e.g. a joke or mishap) may be described in some dialects of English as 'an absolute classic'. "Classic" should not be confused with ''classical'', which refers specifically to certain cultural styles, especially in music and architecture: styles generally taking inspiration from the Classical tradition, hence classicism. ...

Opperman Motor Cart, Bolnhurst - Geograph
: ''There are also several persons called Opperman, listed at Opperman (other)'' S E Opperman was a tractor manufacturer in England. After he saw the Bond Minicar he decided to build his own four-wheel microcar at a factory in Elstree, Hertfordshire. Unicar T The first model was the Unicar T, designed by Lawrie Bond, and built between 1956 and 1959. It looked like a miniature two door saloon with 2+2 seating and was the cheapest car at the 1956 London Motor Show, but it was even cheaper if built as a kit when it could be had without engine for £170. A complete car cost £400. The body was made in fibreglass mounted on a steel tube chassis and had neither separate bonnet nor boot lid. The engine was placed in the middle of the rear seating area giving two small seats on either side of the engine. Since it had no differential for the rear wheels they were placed close together. The front suspension was independent using coil springs and struts and at the rear trail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-wheel Tractor
Two-wheel tractor or walking tractor (french: motoculteur, russian: мотоблок (motoblok), german: Einachsschlepper) are generic terms understood in the US and in parts of Europe to represent a single-axle tractor, which is a tractor with one axle, self-powered and self-propelled, which can pull and power various farm implements such as a trailer, cultivator or harrow, a plough, or various seeders and harvesters. The operator usually walks behind it or rides the implement being towed. Similar terms are mistakenly applied to the household rotary tiller or power tiller; although these may be wheeled and/or self-propelled, they are not tailored for towing implements. A two-wheeled tractor specializes in pulling any of numerous types of implements, whereas rotary tillers specialize in soil tillage with their dedicated digging tools. This article concerns two-wheeled tractors as distinguished from such tillers. Definition Research has identified a number of terms used to ...

National Research Development Corporation
The National Research Development Corporation (NRDC) was a non-departmental government body established by the British Government to transfer technology from the public sector to the private sector. History The NRDC was established by Attlee's Labour government in 1948 to meet a perceived need at the time to exploit the many products that had been developed during World War II by the Defence Research Establishments. It was set up by the Board of Trade under the Development of Inventions Act 1948 and the first managing director was Lord Giffard. The NRDC was established in India in 1953 to help develop and promote technologies developed at various national R&D institutions. The first commercial size hovercraft, the SR.N1, was built under a contract let by the NRDC to Saunders-Roe in 1958. In 1981, the NRDC was combined with the National Enterprise Board ('NEB') to form the British Technology Group ('BTG'). Operations Typically the NRDC would patent the product for commerci ...

Tractor Tyre
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 "tractor" us ...

Douglas (motorcycles)
Douglas was a British motorcycle manufacturer from 1907–1957 based in Kingswood, Bristol, owned by the Douglas family, and especially known for its horizontally opposed twin cylinder engined bikes and as manufacturers of speedway machines. The company also built a range of cars between 1913 and 1922. History The brothers William and Edwin Douglas founded the Douglas Engineering Company in Bristol in 1882. Initially doing blacksmith work, they progressed to foundry work. Joseph F. Barter's Light Motors Ltd. was one of Douglas's customers. Barter built a single-cylinder bicycle engine between 1902 and 1904; he then developed the Fée bicycle engine system. The Fée's 200 cc flat-twin engine was mounted in-line with the frame, using chain drive to a countershaft beneath (with clutch); this then used a drive belt to power the bicycle's rear wheel. Barter founded Light Motors Ltd. to build the Fée system. Production began in 1905; the Fée's name was anglicized to Fairy sh ...

Kingpin (automotive Part)
The kingpin (also king-pin, king pin and k pin) is the main pivot in the steering mechanism of a car or other vehicle. The term is also used to refer to part of a fifth wheel coupling apparatus for a semi and its trailer or other load. History Originally, with the 'turntable' steering of horse-drawn wagons, this was a single pin on which the moveable axle was pivoted beneath the wagon's frame. This located the axle from side to side, but the weight of the wagon was carried on a circular wooden ring turntable surrounding this. Similar centre pivot steering was used by steam traction engines, the kingpin being mounted on the 'perch bracket' beneath the boiler. Some early cars also used centre pivot steering, although it became apparent that it was unsuitable for their increasing speeds. Ackermann steering separates the steering movement into two pivots, one near the hub of each front wheel. The beam axle between them remains fixed relative to the chassis, linked by the suspensi ...

The town's film and TV studios are commonly known as Elstree Studios. History One of the earliest mentions of Bosci de Boreham (Wood of Boreham), is in 1188: :"In 1188 Pope Clement granted to the kitchen of the monastery the whole land of Elstree. He also gave to the Abbey the wood of Boreham for the feeding of the swine."
