A pulley is a wheel on an axle or shaft enabling a taut cable or belt passing over the wheel to move and change direction, or transfer power between itself and a shaft. A sheave or pulley wheel is a pulley using an axle supported by a frame or shell (block) to guide a cable or exert force.
In 1945 the first "Record" two-wheel power mower came off the line. In 1950 The Bucher KT 10 'walking' tractor for tillage and other farm related work went into production. In 2003 Bucher sold the two-wheel tractor division. Over this period a total of 116,000 two-wheel motor-driven machines had been delivered. [35]
The Rj-35 used a Clinton B-1200 engine with a belt driven transmission. When equipped with a Briggs & Stratton 2.5 horsepower (1.9 kW) engine, the model of the tractor became RJ-25. The attachments remained the same for the RJ series. From 1956-1957, wheel horse changed the color of the wheels from black into an almond color.
In a belt drive system, idlers are often used to alter the path of the belt, where a direct path would be impractical.. Idler pulleys are also often used to press against the back of a pulley in order to increase the wrap angle (and thus contact area) of a belt against the working pulleys, increasing the force-transfer capacity.
The larger contact area, coupled with the cleats, or grousers, on the track shoes, allows vastly superior traction that results in a much better ability to push or pull large loads where wheeled vehicles would dig in. Bulldozers, which are most often tracked, use this attribute to rescue other vehicles (such as wheel loaders) which have become ...

Supercharger drive belt in a dragster. A toothed belt, timing belt, cogged belt, cog belt, or synchronous belt is a flexible belt with teeth moulded onto its inner surface. Toothed belts are usually designed to run over matching toothed pulleys or sprockets. Toothed belts are used in a wide array of mechanical devices where high power ...
It is a stepless, fully-automatic transmission, consisting of a V-shaped drive-belt, and two pulleys, each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle or nearer the rim, depending on the separation of the cones. These are synchronized so that the belt always remains at the same optimal tension.
