John Deere Tractor
Deere & Company, the firm founded by John Deere, began to expand its range of John Deere equipment to include the tractor business in 1876. The Deere company briefly experimented with building its own tractor models, the most successful of which was the Dain all-wheel drive. Foundation to 1948 Dain all-wheel drive The Dain all-wheel drive was the first tractor produced by John Deere, and had only a single rear wheel. In 1911, Deere purchased the Dain Manufacturing Company of Ottumwa, Iowa. The next year, Deere decided to design its own tractor, and Dain founder, Joseph Dain Sr., was directed to design that tractor. After several prototypes, the design was finalized in 1917, and 100 production units were ordered. By 1919 when that production run was complete, Deere had purchased the Waterloo Boy Company. Although the Dain AWD was ahead of its time, with features such as a shift-on-the-fly transmission, Deere halted production in late 1919, partly because the cost of the Dain t ...

John Deere (inventor)
John Deere (February 7, 1804 – May 17, 1886) was an American blacksmith, businessman, inventor and politician. He founded Deere & Company, one of the largest and leading agricultural and construction-equipment manufacturers in the world. Born in Rutland, Vermont, Deere moved to Illinois and invented the first commercially successful steel plow in 1837. Early life John Deere was born on February 7, 1804, in Rutland, Vermont, the third son of William Rinold Deere, a merchant tailor, and Sarah Yeats. After a brief educational period at Middlebury College, at age 17 in 1821, he began an apprenticeship with Captain Benjamin Lawrence, a successful Middlebury blacksmith, and entered the trade for himself in 1826.John Deere: A Biography ; , Deere & Company, official website.

Solid Tire
Airless tires, non-pneumatic tires (NPT), or flat-free tires are tires that are not supported by air pressure. They can be used on small vehicles such as ride-on lawn mowers and motorized golf carts. They also are used on heavy equipment required to operate on sites where risk of tire punctures is high. Tires composed of closed-cell polyurethane foam are also made for bicycles and wheelchairs. Advantages & disadvantages The main advantages of airless tires is that they do not go flat and need to be replaced less frequently. Heavy equipment outfitted with airless tires will be able to carry more weight and engage in more rugged activities. Airless tires generally have higher rolling resistance and provide somewhat less suspension than similarly shaped and sized pneumatic tires. Other problems for airless heavy equipment tires include dissipating the heat buildup that occurs when they are driven. Airless tires are often filled with compressed polymers (plastic) rather than air, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Dreyfuss
Henry Dreyfuss (March 2, 1904 – October 5, 1972) was an American industrial designer. He is known for designing the Western Electric Model 500 telephone, the Westclox Big Ben alarm clock, and the Honeywell T87 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. Sometimes compared to Raymond Loewy and other contemporaries, Dreyfuss was much more than a stylist; he applied common sense and a scientific approach to design problems, making products more pleasing to the eye and hand, safer to use, and more efficient to manufacture and repair. His work helped popularize the role of the industrial designer while also contributing significant advances to the fields of ergonomics, anthropometrics and human factors. Dreyfuss began as a Broadway theatrical designer. Until 1920, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Depression
The Great Depression was a severe global economic downturn from 1929 to 1939. The period was characterized by high rates of unemployment and poverty, drastic reductions in industrial production and international trade, and widespread bank and business failures around the world. The economic contagion began in 1929 in the United States, the largest economy in the world, with the devastating Wall Street stock market crash of October 1929 often considered the beginning of the Depression. Among the countries with the most unemployed were the U.S., the United Kingdom, and Weimar Republic, Germany. The Depression was preceded by a period of industrial growth and social development known as the "Roaring Twenties". Much of the profit generated by the boom was invested in speculation, such as on the stock market, contributing to growing Wealth inequality in the United States, wealth inequality. Banks were subject to laissez-faire, minimal regulation, resulting in loose lending and wides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bankrupt
Bankruptcy is a legal process through which people or other entities who cannot repay debts to creditors may seek relief from some or all of their debts. In most jurisdictions, bankruptcy is imposed by a court order, often initiated by the debtor. Bankrupt is not the only legal status that an insolvent person may have, meaning the term ''bankruptcy'' is not a synonym for insolvency. Etymology The word ''bankruptcy'' is derived from Italian , literally meaning . The term is often described as having originated in Renaissance Italy, where there allegedly existed the tradition of smashing a banker's bench if he defaulted on payment. However, the existence of such a ritual is doubted. History In Ancient Greece, bankruptcy did not exist. If a man owed and he could not pay, he and his wife, children or servants were forced into " debt slavery" until the creditor recouped losses through their physical labour. Many city-states in ancient Greece limited debt slavery to a perio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axle Track
In Car, automobiles (and other wheeled vehicles which have two wheels on an axle), the axle track is the distance between the hub Flange, flanges on an axle. Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. In the case of an axle with dual wheels, the centerline of the dual wheel assembly is used for the wheel track specification. Axle and wheel track are commonly measured in millimetres or inches. Common usage Despite their distinct definitions, ''axle track'', (not to be frequently and incorrectly used interchangeably as ''wheel track'' and ''track width''), normally refers to the distance between the centerline of the wheels. For a vehicle with two axles, the term can be expressed as ''front track'' and ''rear track''. For a vehicle with more than two axles, the axles are normally numbered for reference. Offset wheel track In vehicles with Wheel_sizing#Offset, offset wheels, wheel track is distinct from axle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Row Crop
A row crop is a crop that can be planted in rows wide enough to allow it to be tilled or otherwise cultivated by agricultural machinery, machinery tailored for the seasonal activities of row crops. Such crops are sown by drilling or transplanting rather than broadcasting. They are often grown in market gardening (truck farming) contexts or in kitchen gardens. Growing row crops first started in Ancient China in the 6th century BC. The distinction is significant in crop rotation strategies, where land is planted with row crops, close-growing grains, and sod-forming crops in a sequence meant to protect the quality of the soil while maximizing the soil's annual productivity. As much of 20% of crops worldwide are irrigated, with some crops such as rice and maize benefiting from the extra water. During the growing season, the inter-row spaces are hoed two to four times and the rows are weeded to conserve moisture and improve aeration. As a result, the soil's microbiological activi ...

John Deere Model G
The John Deere Model G tractor was a large three-plow row-crop tractor produced by John Deere from 1937 to 1953, with successor models produced until 1961. It was followed by the 70, 720, and 730. Description and production The G was released by John Deere in 1937, and it was a general-purpose row-crop tractor, with enough power to manage three plows. As with most row-crop tractors, the spacing between the rear wheels could be adjusted to suit row spacings. On later models, the front wheels were offered with wide and narrow wheel arrangements. The tractor was equipped with a two-cylinder side-by-side engine, of displacement. Both gasoline and kerosene-fueled versions were available. About 64,000 Model Gs were built at the John Deere factory in Waterloo, Iowa. Sale price was about $2,600.MacMillan, p. 69 The G was originally to be the Model F, since A, B, C (the GP), D and E (for stationary engines) had all been used, but Deere wished to avoid confusion with the Farmall F- ...

Farmall Tractor
Farmall was a model name and later a brand name for tractors manufactured by International Harvester (IH), an American truck, tractor, and construction equipment company. The Farmall name was usually presented as McCormick-Deering Farmall and later McCormick Farmall in the evolving brand architecture of IH. Farmall was a prominent brand in the 20th-century trend toward the mechanization of agriculture in the US. Its general-purpose machines' origins were in row-crop tractors, a category that they helped establish and in which they long held a large market share. During the decades of Farmall production (1920s to 1980s), most Farmalls were built for row-crop work, but many orchard, fairway, and other variants were also built. Most Farmalls were all-purpose tractors that were affordable for small to medium-sized family farms, and could do enough of the tasks needed on the farm that the need for hired hands was reduced and for working horses or mules eliminated. The original ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Deere Model A
The John Deere Model A is a row crop tractor manufactured by Deere & Company. The A was produced in a wide variety of versions for special-purpose cultivation. It received a styling upgrade in 1939 and electric starting in 1947. With the advent of John Deere's numerical model numbering system, the A became the John Deere 60, and later the 620 and 630, 3010, 3020, 4030, 4040, 4050, 4055, and ended with the 7610. Description and production The Model A was intended to directly compete with McCormick's Farmall tractors. With over 290,000 sold by the end of its original production in 1952, it was a popular tractor that used Deere & Company's two cylinder design. Early tractors burnt distillate, a petroleum byproduct similar to kerosene, which became a selling point owing to the fuel's low price. Deere & Company's two cylinder design sprang from keeping costs low, improving their current engine rather than develop a new engine. These engines made a very distinctive sound giving them ...
