John Deere Model L
The John Deere Model L tractor was a small one-plow row-crop tractor produced by John Deere from 1937 to 1946. Description and production The L was first produced in 1937. Unlike most John Deere tractors, it was designed in John Deere's Dubuque Wagon Works plant in Dubuque, Iowa, and did not resemble previous Deere products. It departed further from tradition by using a non-Deere engine, a Hercules two-cylinder engine mounted in line, rather than transversely, as had been traditional, mated to a three-speed Ford transmission, with the engine mounted far forward over the wide-set front wheels. This created a distinctive empty gap between the engine and operator. Late 1938 models were restyled in line with other Deere tractors, with Henry Dreyfuss cowlings and grilles. In 1940. the LA was introduced, using a John Deere engine, and the L received a Deere engine in lieu of the Hercules. The LA introduced a power take-off to the L line. Both the L and LA were produced at the same time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Row-crop 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 "tractor" ...

Henry Dreyfuss
Henry Dreyfuss (March 2, 1904 – October 5, 1972) was an American industrial design pioneer. Dreyfuss is known for designing some of the most iconic devices found in American homes and offices throughout the twentieth century, including the Western Electric Model 500 telephone, the Westclox Big Ben alarm clock, and the Honeywell round thermostat.

Career Dreyfuss, a native of Brooklyn, New York City, is one of the celebrity industrial designers of the 1930s and 1940s who pioneered his field. Dreyfuss dramatically improved the look, feel, and usability of dozens of consumer products.

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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nebraska Tractor Test Laboratory
The Nebraska Tractor Test Laboratory (NTTL) is a program operated by the University of Nebraska in accordance with Nebraska law to test the performance of agricultural equipment that is to be sold in the United States for compliance with OECD standards. The NTTL has operated since 1920 as the common standard reference for tractor performance in the United States. History Impetus for the Nebraska Tractor Test Act of 1919, or Nebraska Tractor Law, came from a Nebraska farmer, Wilmot F. Crozier, who had been disappointed with the performance of several tractors he had bought. One had been marketed as a Ford tractor, but the Ford Tractor Company of the time was completely unrelated to the Ford Motor Company, and its products were of poor quality. The new law was enacted to address problems of false advertising of tractor features and capabilities, requiring that all agricultural tractors sold in Nebraska must have their performance verified by three engineers. The laboratory was establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
