Agricultural Machinery Industry
The agricultural machinery industry or agricultural engineering industry is the part of the Industry (economics), industry, that produces and maintain tractors, agricultural machinery and agricultural implements used in farming or other agriculture. This branch is considered to be part of the machinery industry. History :''See also history of Agricultural machinery#History, Agricultural machinery and Mechanised agriculture#History, Mechanised agriculture'' 19th century The agricultural machinery industry emerged in Britain and the United States in the 19th century. Until then the common tools of farming were the plough and the sickle.R.C. Gifford. Agricultural Engineering in Development: Concepts and principles'' 1992. pp. 7–8 These iron agricultural implements were often made by blacksmiths in the local village, who regularly also acted as farrier. In the first part of the 19th century some of the early agricultural machine manufacturers arose from these blacksmith workshop ...

Industry (economics)
In microeconomics, an industry is a branch of an economy that Production (economics) , produces a closely related set of raw materials, Good (economics) , goods, or Service (economics) , services. For example, one might refer to the wood industry or to the insurance industry. When evaluating a single group or company, its dominant source of revenue is typically used by industry classifications to classify it within a specific industry. For example the International Standard Industrial Classification (ISIC) – used directly or through derived classifications for the official statistics of most countries worldwide – classifies "statistical units" by the "economic activity in which they mainly engage". Industry is then defined as "set of statistical units that are classified into the same ISIC category". However, a single business need not belong just to one industry, such as when a large business (often referred to as a conglomerate (company), conglomerate) Diversification (ma ...

Ploughing Engine
A traction engine is a 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 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 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 tractors saw them fall out of favour, although some conti ...

Combine Harvester
The modern combine harvester, also called a combine, is a machine designed to harvest a variety of cultivated seeds. Combine harvesters are one of the most economically important labour-saving inventions, significantly reducing the fraction of the population engaged in agriculture. Among the crops harvested with a combine are wheat, rice, oats, rye, barley, Maize, corn (maize), sorghum, millet, soybeans, flax (linseed), sunflowers and rapeseed (canola). The separated straw (consisting of stems and any remaining leaves with limited nutrients left in it) is then either chopped onto the field and ploughed back in, or laid out in rows, ready to be Baler, baled and used for bedding and cattle feed. The name of the machine is derived from the fact that the harvester combined multiple separate harvesting operations – Reaper, reaping, threshing or winnowing and gathering – into a single process around the start of the 20th century. A combine harvester still performs its functions ac ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Waterloo Boy
The Waterloo Gasoline Engine Company was the first company to manufacture and sell gasoline powered farm tractors. Based in Waterloo, Iowa, the company was created by John Froelich and a group of Iowa businessmen in 1893, and was originally named the Waterloo Gasoline Traction Engine Company. In 1892, Froelich built a successful gasoline-powered tractor, and the new company was given the opportunity to manufacture and sell the tractor Froelich designed. The tractor was not successful commercially, and of the four tractors built by the company only two were purchased, and these were later returned to the company by unsatisfied customers. In 1895, the company was sold to John W. Miller and renamed the Waterloo Gasoline Engine Company. Miller decided to stop producing tractors and instead focus on building plain gasoline engines. Background Following several years of research and development, the company once again began to manufacture tractors in 1911, but none would sell well until ...

Power (physics)
Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. Power is a Scalar (physics), scalar quantity. Specifying power in particular systems may require attention to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction (engineering), traction force on the wheels, and the velocity of the vehicle. The output power of a Engine, motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a electrical circuit, circuit is the product of the electric current, current flowing through the element and of the voltage across the element. Definition Power is the Rate (mathematics), rate with respect to time at which work is done or, more generally, the rate of change of total mechanical energy. It is ...

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Petrol Engine
A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as '' E10'' and '' E85''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (reciprocating engine, piston engine), turbine blades (gas turbine), a Wankel engine, rotor (Wankel engine), or a propulsive nozzle, nozzle (jet engine). This force moves the component over a distance. This process transforms chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. The first commercially successful internal combustion engines were invented in the mid-19th century. The first modern internal combustion engine, the Otto engine, was designed in 1876 by the German engineer Nicolaus ...

Steam Tractor
A steam tractor is a tractor powered by a steam engine which is used for pulling. In North America, the term ''steam tractor'' usually refers to a type of agriculture, agricultural tractor powered by a steam engine, used extensively in the late 19th and early 20th centuries. In Great Britain, the term ''steam tractor'' is more usually applied to the smallest models of traction engine – typically those weighing seven tons or less – used for hauling small loads on public roads. Although known as ''light steam tractors'', these engines are generally just smaller versions of the "traction engine#Road locomotive, road locomotive". This article concentrates on the steam-powered agricultural vehicles intended for the direct-pulling of plows and other implements (as opposed to cable-hauling). Development Owing to differences in soil conditions, the development of steam-powered agricultural machines differed considerably on either side of the Atlantic Ocean, Atlantic ...
