2. 牽引自動車 – A trailer is generally an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials, sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities, where people can camp or stay have been referred to as trailers. In earlier days, many vehicles were towable trailers. In the United States, the term is used interchangeably with travel trailer and mobile home, varieties of trailers. Their origins lay in utility trailers built in a fashion to horse-drawn wagons. A trailer park is an area where homes are placed for habitation. In the United States trailers ranging in size from single-axle dollies to 6-axle,13 ft 6 in high,53 ft 0 in long semi-trailers are commonplace. The latter, when towed as part of a tractor-trailer or 18-wheeler, enclosed toy trailers and motorcycle trailers can be towed by commonly accessible pickup truck or van, which generally require no special permit beyond a regular drivers license. Other trailers, such as utility trailers and travel trailers or campers come in single and multiple axle varieties, there also exist highly specialized trailers, such as genset trailers, pusher trailers and their ilk that are also used to power the towing vehicle. Others are custom-built to hold entire kitchens and other specialized equipment used by carnival vendors, there are also trailers for hauling boats. Popular campers use lightweight trailers, aerodynamic trailers that can be towed by a small car and they are built to be lower than the tow vehicle, minimizing drag. Others range from two-axle campers that can be pulled by most mid-sized pickups to trailers that are as long as the host countrys law allows for drivers without special permits. Larger campers tend to be fully integrated recreational vehicles, which often are used to tow single-axle dolly trailers to allow the driver to bring small cars on their travels, a semi-trailer is a trailer without a front axle. A large proportion of its weight is supported either by a tractor or by a detachable front axle assembly known as a dolly. A semi-trailer is normally equipped with legs, called landing gear, which can be lowered to support it when it is uncoupled. In the United States, a single trailer cannot exceed a length of 57 ft 0 in on interstate highways, semi-trailers vary considerably in design, ranging from open-topped grain haulers through Tautliners to normal-looking but refrigerated 13 ft 6 in x 53 ft 0 in enclosures. Many semi-trailers are part of semi-trailer trucks, other types of semi-trailers include dry vans, flatbeds and chassis. A full trailer is a used in the United States for a freight trailer supported by front and rear axles
JCBのように建機メーカーが農機業界に参入すること自体はそんなに珍しいことではありません。キャタピラーは以前大型クローラトラクターを生産し、現在でも大型普通型コンバインを生産しています。日立建機の子会社である日立建機ティエラもクボタからのOEMながらトラクターや自脱式コンバインを販売しています。またコマツはスタートがクローラトラクタで昔はホイールトラクタを自社開発、生産したり、インターナショナルのトラクター等を輸入・生産したりしていました。さらにゼノアが出来る以前から動噴や刈り払い機などを生産・販売していました
最も右側はアクセルペダル(スロットル)であるが、ペダルによるスロットル操作でのトラクターの速度調節は、自動車と同様に簡単である(イギリスでは道路を走行する場合、スピードをコントロールするためにフット・ペダルを使用することが義務付けられている)。古い機種ではペダルが装備されていないものもあり、後年の改造で取り付ける例がみられる。なお、圃場での作業時、スロットルはステアリングホイール付近に装備された、手で扱うハンドスロットルレバーから操作することを基本とし、ペダル操作は補助的に用いることが多い。揺れる車上でのペダル操作では長時間のエンジン回転数の維持(定速運転)が困難なためである。ハンドスロットルレバーは強めのフリクションで動きがやや重くされており、動揺時でもエンジンの回転数を一定に保てるようになっている。これは作業機を適正な速度で使用するために重要な機構であり、運転席を離れ、トラクターを定置した状態での作業にも必要である。
3. 農業機械 – Agricultural machinery is machinery used in farming or other agriculture. There are many types of equipment, from hand tools and power tools to tractors. Diverse arrays of equipment are used in organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an part of how the world is fed. With the coming of the Industrial Revolution and the development of complicated machines. Instead of harvesting grain by hand with a blade, wheeled machines cut a continuous swath. Instead of threshing the grain by beating it with sticks, threshing machines separated the seeds from the heads, the first tractors appeared in the late 19th century. Power for agricultural machinery was supplied by ox or other domesticated animals. With the invention of power came the portable engine, and later the traction engine. Agricultural steam engines took over the heavy pulling work of oxen, the steam-powered machines were low-powered by todays standards but, because of their size and their low gear ratios, they could provide a large drawbar pull. Their slow speed led farmers to comment that tractors had two speeds, slow, and damn slow, the internal combustion engine, first the petrol engine, and later diesel engines, became the main source of power for the next generation of tractors. These engines also contributed to the development of the self-propelled, combined harvester and thresher, instead of cutting the grain stalks and transporting them to a stationary threshing machine, these combines cut, threshed, and separated the grain while moving continuously through the field. Combines might have taken the job away from tractors. They are used to push implements—machines that till the ground, plant seed, tillage implements prepare the soil for planting by loosening the soil and killing weeds or competing plants. The best-known is the plow, the ancient implement that was upgraded in 1838 by John Deere. Plows are now used frequently in the U. S. than formerly, with offset disks used instead to turn over the soil. The most common type of seeder is called a planter, and spaces seeds out equally in long rows, some crops are planted by drills, which put out much more seed in rows less than a foot apart, blanketing the field with crops. Transplanters automate the task of transplanting seedlings to the field, with the widespread use of plastic mulch, plastic mulch layers, transplanters, and seeders lay down long rows of plastic, and plant through them automatically

差動装置(デファレンシャル)の働きによって通常は片方の車輪にしか駆動力が伝達されないが、深い泥濘地からの脱出や急坂を移動するためスリップしては危険なとき、あるいはプラウ作業などで直進性が保てないときには、両方の車軸を機械的に直結する「デフロック機構」があり、ペダルやレバーにより作動させ安定した走行が出来るが、通常の走行時に作動するとハンドルを操作しても方向が変わらず危険であるため、誤操作を防ぐ目的で、通常の運転姿勢では操作しにくい場所に配置されていることが多い。
農業機械・芝刈り機事業による利益が全体の利益の大半を占めていることがわかります。少ない年でも50%、多い年だと80%を占めています。これに次いで、金融事業、建設林業機械事業となっています。また、農業機械・芝刈り機事業および金融事業の利益はこの12年間で成長していますが、建設林業機械事業の利益は2009年以降回復してはいますが、2007年以前の水準には達しておらず減少傾向にあると言えます。これは建設林業機械事業の利益率が以前よりも低下していることが原因です。Deere & Companyは建設林業機械事業の分野での競争力を失いつつあるのかもしれません。ただし、2015年10月期の利益率は8.8%あり低い水準ではありません。あくまでも過去と比較した場合です。
8. タイヤ – A tire or tyre is a ring-shaped vehicle component that covers the wheels rim to protect it and enable better vehicle performance. Most tires, such as those for automobiles and bicycles, provide traction between the vehicle and the road providing a flexible cushion that absorbs shock. The materials of modern tires are synthetic rubber, natural rubber, fabric and wire, along with carbon black. They consist of a tread and a body, the tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, the first versions of tires were bands of metal fitted around wooden wheels to prevent wear and tear. Pneumatic tires are used on many types of vehicles, including cars, bicycles, motorcycles, buses, trucks, heavy equipment, and aircraft. Metal tires are used on locomotives and railcars, and solid rubber tires are still used in various non-automotive applications, such as some casters, carts, lawnmowers. The etymology of tire is that the word is a form of attire. The spelling tyre does not appear until the 1840s when the English began shrink fitting railway car wheels with malleable iron, nevertheless, traditional publishers continued using tire. The Times newspaper in Britain was still using tire as late as 1905, the spelling tyre began to be commonly used in the 19th century for pneumatic tires in the UK. However, over the course of the 20th century, tyre became established as the standard British spelling, the earliest tires were bands of leather, then iron, placed on wooden wheels, used on carts and wagons. The tire would be heated in a fire, placed over the wheel and quenched, causing the metal to contract. A skilled worker, known as a wheelwright, carried out this work, the outer ring served to tie the wheel segments together for use, providing also a wear-resistant surface to the perimeter of the wheel. The word tire thus emerged as a variant spelling to refer to the bands used to tie wheels. The first patent for what appears to be a standard pneumatic tire appeared in 1847 lodged by the Scottish inventor Robert William Thomson, however, this never went into production. The first practical pneumatic tire was made in 1888 on May Street, Belfast, by Scots-born John Boyd Dunlop and it was an effort to prevent the headaches of his 10-year-old son Johnnie, while riding his tricycle on rough pavements. His doctor, John, later Sir John Fagan, had prescribed cycling as an exercise for the boy, Fagan participated in designing the first pneumatic tires. In Dunlops tire patent specification dated 31 October 1888, his interest is only in its use in cycles, in September 1890, he was made aware of an earlier development but the company kept the information to itself

7. ステアリング – Steering is the collection of components, linkages, etc. which allows any vehicle to follow the desired course. An exception is the case of transport by which rail tracks combined together with railroad switches provide the steering function. The primary purpose of the system is to allow the driver to guide the vehicle. Other arrangements are found on different types of vehicles, for example. The basic aim of steering is to ensure that the wheels are pointing in the desired directions and this is typically achieved by a series of linkages, rods, pivots and gears. The angle the wheels make with the plane also influences steering dynamics as do the tires. The rack and pinion design has the advantages of a degree of feedback. A disadvantage is that it is not adjustable, so that when it does wear and develop lash, BMW began to use rack and pinion steering systems in the 1930s, and many other European manufacturers adopted the technology. American automakers adopted rack and pinion steering beginning with the 1974 Ford Pinto, older designs use two main principles, the worm and sector design and the screw and nut. Both types were enhanced by reducing the friction, for screw and nut it is the ball mechanism. The steering column turns a large screw which meshes with nut by recirculating balls and this design is still in use in trucks and other large vehicles, where rapidity of steering and direct feel are less important than robustness, maintainability, and mechanical advantage. The worm and sector was a design, used for example in Willys and Chrysler vehicles. To reduce friction the sector is replaced by a roller or rotating pins on the rocker shaft arm, other systems for steering exist, but are uncommon on road vehicles. Power steering helps the driver of a vehicle to steer by directing some of its power to assist in swiveling the steered road wheels about their steering axes. To alleviate this auto makers have developed power steering systems, or more correctly power-assisted steering, there are two types of power steering systems, hydraulic and electric/electronic. A hydraulic-electric hybrid system is also possible, a hydraulic power steering uses hydraulic pressure supplied by an engine-driven pump to assist the motion of turning the steering wheel. In EPS, the amount of assistance is easily tunable to the type, road speed. An added benefit is the elimination of environmental hazard posed by leakage, an outgrowth of power steering is speed sensitive steering, where the steering is heavily assisted at low speed lightly assisted at high speed

5. 内燃機関 – An internal combustion engine is a heat engine where the combustion of a fuel occurs with an oxidizer 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 applied typically to pistons, turbine blades, rotor or a nozzle. This force moves the component over a distance, transforming chemical energy into mechanical energy. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1859, firearms are also a form of internal combustion engine. Working fluids can be air, hot water, pressurized water or even liquid sodium, ICEs are usually powered by energy-dense fuels such as gasoline or diesel, liquids derived from fossil fuels. While there are many applications, most ICEs are used in mobile applications and are the dominant power supply for vehicles such as cars, aircraft. Typically an ICE is fed with fossil fuels like natural gas or petroleum products such as gasoline, there is a growing usage of renewable fuels like biodiesel for compression ignition engines and bioethanol or methanol for spark ignition engines. Hydrogen is sometimes used, and can be made from fossil fuels or renewable energy. Various scientists and engineers contributed to the development of internal combustion engines, in 1791, John Barber developed a turbine. In 1794 Thomas Mead patented a gas engine, also in 1794 Robert Street patented an internal combustion engine, which was also the first to use liquid fuel, and built an engine around that time. In 1798, John Stevens built the first American internal combustion engine, in 1807, Swiss engineer François Isaac de Rivaz built an internal combustion engine ignited by electric spark. In 1823, Samuel Brown patented the first internal combustion engine to be applied industrially, in 1860, Belgian Jean Joseph Etienne Lenoir produced a gas-fired internal combustion engine. In 1864, Nikolaus Otto patented the first atmospheric gas engine, in 1872, American George Brayton invented the first commercial liquid-fuelled internal combustion engine. In 1876, Nikolaus Otto, working with Gottlieb Daimler and Wilhelm Maybach, patented the compressed charge, in 1879, Karl Benz patented a reliable two-stroke gas engine. In 1892, Rudolf Diesel developed the first compressed charge, compression ignition engine, in 1926, Robert Goddard launched the first liquid-fueled rocket. In 1939, the Heinkel He 178 became the worlds first jet aircraft, at one time, the word engine meant any piece of machinery — a sense that persists in expressions such as siege engine. A motor is any machine that produces mechanical power, traditionally, electric motors are not referred to as Engines, however, combustion engines are often referred to as motors. In boating an internal combustion engine that is installed in the hull is referred to as an engine, reciprocating piston engines are by far the most common power source for land and water vehicles, including automobiles, motorcycles, ships and to a lesser extent, locomotives

10. 四輪駆動 – An all-wheel drive vehicle is one with a powertrain capable of providing power to all its wheels, whether full-time or on-demand. The most common forms of all-wheel drive are, 4×4 Reflecting two axles with wheels on each capable of being powered. 6×6 Reflecting three axles with wheels on each capable of being powered. 8×8 Reflecting four axles with wheels on each capable of being powered. This distinction in terminology is not generally used outside North America, when tyre grip is good during road driving a differential is used between the axles to avoid driveline windup. This is not required off-road, as the grip allows the tyres to slip relative to each other. All-wheel drive vehicles designed for extensive off-road use may not have such a differential, selectable 4WD also avoids this problem and requires only a simple dog clutch in the transfer case, rather than a differential. For this reason, most early off-road vehicles used system, e. g. Jeep. Esoteric vehicles such as the high-powered Jensen FF followed by the AMC Eagle, Subaru Leone and these, particularly the Quattro, would extensively develop this drivetrain with the use of viscous couplings and differentials to provide a safe and drivable car. The first off-road / on-road hybrids such as the Range Rover also chose the permanent all wheel drive system rather than manual selection, selectable 4WD has both axles rigidly coupled together, which has some advantages in very poor off-road conditions. To gain the advantage in a permanent AWD system with a differential. As this control is frequently misunderstood and mis-used, which can cause damage due to wind-up. Front-wheel drive Rear-wheel drive All-terrain vehicle Two-wheel drive H-drive Four Wheel Drive or FWD, one of the first companies, from 1909, to build four-wheel drive vehicles
