Agricultural Machine Industry
The agricultural machinery industry or agricultural engineering industry is the part of the 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 and 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. p. 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 workshops,Jan H. Maas (1994) ''De Nederlandse agrosector: geografie en dynamiek'' p.177 such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industry (economics)
In macroeconomics, 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 (m ...

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 continu ...

Combine Harvester
The modern combine harvester, or simply combine, is a versatile machine designed to efficiently harvest a variety of grain crops. The name derives from its combining four separate harvesting operations—reaping, threshing, gathering, and winnowing— to a single process. Among the crops harvested with a combine are wheat, rice, oats, rye, barley, corn (maize), sorghum, soybeans, flax (linseed), sunflowers and rapeseed. The separated straw, left lying on the field, comprises the stems and any remaining leaves of the crop with limited nutrients left in it: the straw is then either chopped, spread on the field and ploughed back in or baled for bedding and limited-feed for livestock. Combine harvesters are one of the most economically important labour-saving inventions, significantly reducing the fraction of the population engaged in agriculture. History In 1826 in Scotland, the inventor Reverend Patrick Bell designed (but did not patent) a reaper machine, which used the ...

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 had invented the first practical 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 se ...

Power (physics)
In 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. In older works, power is sometimes called ''activity''. Power is a scalar quantity. Power is related to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction force on the wheels, and the velocity of the vehicle. The output power of a 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 circuit is the product of the current flowing through the element and of the voltage across the element. Definition Power is the rate with respect to time at which work is done; it is the time derivative of work: P =\frac where is power, is work, and is time. If a constant force F is applied throughout a distance x, the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called 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). Diesel engines work by compressing only air, or air plus 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 the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrol Engine
A petrol engine (gasoline engine in American 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''). Most petrol engines use spark ignition, unlike diesel engines which typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also been produced using the Miller cycle and Atkinson cycle. Layout Most petrol-powered piston engines are straight engines or V engines. However, flat engines, W engines and other layouts are sometimes used. Wankel engines are classified by the number of rotors used. Compression ratio Cooling Petrol engines are either air-cooled or water-cooled. Ignition Petrol e ...

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 ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...

Steam Tractor
:''This article refers to the steam-powered agricultural tractor; for other types of steam tractor, see: Traction engine'' A steam tractor is a vehicle powered by a steam engine which is used for pulling. In North America, the term ''steam tractor'' usually refers to a type of 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 ' road locomotive'. This article concentrates on the steam-powered agricultural vehicles intended for the direct-pulling of ploughs and other implements (as opposed to cable-hauling). Development (Great Britain) Owing to differences in soil conditions, the development of steam-powered agricult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mann’s Patent Steam Cart And Wagon Company
Mann's Patent Steam Cart and Wagon Company manufactured steam powered road vehicles in Leeds, England. History Early history The company was founded by James Hutchinson Mann, a native of Leeds. Mann had been apprenticed to J&H McLaren & Co. and also worked for Marshall, Sons & Co. of Gainsborough. In January 1894 he commenced a partnership with Sidney Charlesworth under the title Mann and Charlesworth, and their works was in Canning Street, off Dewsbury Road, Leeds. This company manufactured traction engines, portable engines and steam rollers. They also did conversions on engines from simple to Compound steam engine, compound operation, and made boilers. One of their notable inventions was the single-eccentric reversing gear. This compact device allowed the sequence of valve opening of a steam engine to be changed, both in terms of "cut-off" and "direction" without the need for link motion and all the associated levers. In 1898 Mann and Charlesworth produced, on behalf of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
