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。
1960年代以降は乗用型トラクターの普及が進み、1970年代には、当初の歩行型トラクターを利用した部分的機械化体系から、乗用型トラクターを中心とした一貫的機械化体系への進展が見られている。1974年(昭和49年)に337万台というピークを迎えた歩行型トラクターがその後やや減少に移るのに対し、乗用型トラクタの総数は1961年(昭和36年)の7000台から、その10年後の1971年(昭和46年)には26万7200台、1977年(昭和52年)には83万2200台と大幅な増加を見せている[4]。そして、当初の共同所有から次第に戸別所有へと所有の形態も変化していった。
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 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

The Faraday disk was the first electric generator. The horseshoe-shaped magnet (A) created a magnetic field through the disk (D). When the disk was turned, this induced an electric current radially outward from the center toward the rim. The current flowed out through the sliding spring contact m, through the external circuit, and back into the center of the disk through the axle.
6. ボンネット (自動車) – The hood or bonnet is the hinged cover over the engine of motor vehicles that allows access to the engine compartment for maintenance and repair. In British terminology, hood refers to a cover over the passenger compartment of the car. On passenger cars, a hood may be held down by a concealed latch and it is designed to protect a car from thefts, damage and sudden hood opening on the road. The hood release system is common on the most of vehicles and usually consists of interior hood latch handle, hood release cable, the hood latch handle is usually located below the steering wheel, beside the drivers seat or set into the door frame. When a driver pulls a hood latch handle the hood panel pops up, on race cars or cars with aftermarket hoods the hood may be held down by hood pins. A hood may sometimes contain a hood ornament, hood scoop, power bulge, hoods are typically made out of steel, but aluminum is rapidly gaining popularity with auto companies. Aftermarket manufacturers may construct hoods out of fiberglass, carbon fiber, dry carbon, aftermarket hoods are usually sold unpainted or come primered in flat matte black paint. It means that such hoods require additional painting, to choose a paint that match vehicles original shade and hue, special color code is used. This code is printed in the label that is located under the hood or on the driver side door jamb. Some car owners however prefer to leave their black primed hoods unpainted, carbon fiber custom hoods require no painting, as they already come with protective clear coating. In Japan and Europe, regulations have come into effect in recent years that place a limit on the severity of head injury when struck by a motor vehicle. This is leading to more advanced designs, as evidenced by multicone hood inner panel designs as found on the Mazda RX-8. Other changes are being made to use the hood as an active structure and this may be achieved by mechanical or pyrotechnic devices

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
無重力空間において移動中の物体の軌道を変えるために、重力トラクターというものがある。これは対象物と物理的な接続はせず、付近に飛行させた人工衛星等へ重力で徐々に引き寄せることで、対象物の軌道に影響を与えるもの。概念の近いものとしてSF用語では、周りの物体を引力などの力で引き寄せ、念力のように操る光線を、トラクタービームと称している。スター・ウォーズ・シリーズ、レンズマンシリーズ、スタートレック、タイムクライシス4等、数多くの作品に登場した。
金融事業の資産が大変多く、総資産(会社規模)の成長のほとんどが金融事業の資産成長で説明できてしまいます。自社製品の販売ローンのためDeere & Companyは金融事業を行っていますが、そのために大量の資産が必要なのでしょう。また、金融事業がDeere & Companyの好業績を支えている面が大きいと私は考えています。農業機械や建設機械は非常に高価で、これらの購入は農家にとっては大きな負担です。それを補う仕組みとしてDeere & Companyは販売ローンやリースを提供しており、それが他社との差別化を促進し、業績の向上に一役買っていると考えられます。だからこそ、Deere & Companyは金融事業のためにこれだけ多くの金融資産を保有しているのでしょう。

コンピュータ用語では、トラクターとはプリンターの紙送りを行う部分を指す。 これは通常、複写紙や様式紙の両端に空けられているパンチ穴とかみ合うギア、あるいは表面にゴムなど摩擦力の高い素材を用いたベルトやホイールの形状をしている。印字ヘッドに紙を押し込むプッシュトラクターと、印刷した後の部分を引き出すプルトラクターがある。通常はプッシュトラクターが標準搭載されており、紙送り精度を高めるためのオプション品としてプルトラクターが用意されている。
日本における農業用トラクターの導入は、1909年(明治42年)に岩手県雫石町の小岩井農場が導入した蒸気式トラクターと、1911年(明治44年)に北海道斜里町の農場に導入されたアメリカ・ホルト製の内燃機関式トラクターが、それぞれの日本初といわれている[2]。しかし、日本における農業機械の歴史は長らく歩行型耕耘機がそのほとんどを占めており、乗用型トラクターは戦後まで特殊な農牧場で細々と用いられるだけにすぎなかった。
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

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。
右側のペダルのうちの二つはブレーキである。左のブレーキペダルは左後方の車輪を止め、右のブレーキペダルは右後方の車輪を止める。操舵時にこの独立した左右ブレーキを使用することにより、最小回転半径が大幅に減少し、折り返しの際の無駄な動きを不要とする。しかし、一般道の走行時など速度が高いときに使用すると、文字通りの片効きとなって急に向きが変わり危険であるため、作業以外の走行時は左右のペダルを連結して使用する。分離したブレーキペダルは、泥か柔軟なダート(soft dirt)の中でトラクションの損失により空転するタイヤを制御するためにも使用され、デフロックやトラクションコントロールの代用ともなる。作業時にトラクターを停止させるためには、両方のペダルをともに踏む。
9. 車輪 – A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the components of the wheel. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, wheels are also used for other purposes, such as a ships wheel, steering wheel, potters wheel and flywheel. Common examples are found in transport applications, a wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, cognates within Indo-European include Icelandic hjól wheel, tyre, Greek κύκλος kúklos, and Sanskrit chakra, the latter both meaning circle or wheel. The invention of the falls into the late Neolithic. Note that this implies the passage of several wheel-less millennia even after the invention of agriculture and of pottery, precursors of wheels, known as tournettes or slow wheels, were known in the Middle East by the 5th millennium BCE. These were made of stone or clay and secured to the ground with a peg in the center, but required effort to turn. True potters wheels were apparently in use in Mesopotamia by 3500 BCE and possibly as early as 4000 BCE, and the oldest surviving example, which was found in Ur, dates to approximately 3100 BCE. The earliest well-dated depiction of a vehicle is on the Bronocice pot. The oldest securely dated real wheel-axle combination, that from Stare Gmajne near Ljubljana in Slovenia is now dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE. Two types of early Neolithic European wheel and axle are known, a type of wagon construction. They both are dated to c, in China, the wheel was certainly present with the adoption of the chariot in c.1200 BCE, although Barbieri-Low argues for earlier Chinese wheeled vehicles, c.2000 BC. In Britain, a wooden wheel, measuring about 1 m in diameter, was uncovered at the Must Farm site in East Anglia in 2016. The specimen, dating from 1, 100–800 years BCE, represents the most complete, the wheels hub is also present. A horses spine found nearby suggests the wheel may have part of a horse-drawn cart. The wheel was found in a settlement built on stilts over wetland and it is thought that the primary obstacle to large-scale development of the wheel in the Americas was the absence of domesticated large animals which could be used to pull wheeled carriages. The only large animal that was domesticated in the Western hemisphere, Nubians from after about 400 BCE used wheels for spinning pottery and as water wheels
4. 耕耘機 – The operator usually walks behind it or rides the implement being towed. Similar terms are applied to the household rotary tiller or power tiller, although these may be wheeled and/or self-propelled. A two-wheeled tractor specializes in pulling any of numerous types of implements and this article concerns two-wheeled tractors as distinguished from such tillers. Adding to the confusion, agricultural engineers like to classify them as single-axle tractors. For clarity, the rest of this article refers to the self-propelled, single-axle, even zero till/no-till planters and seeders have become available. In plant protection and weed control, two-wheel tractor implements consist of various inter-cultivators and sprayers, for harvesting, available implements are, Forage, Sickle bar mowers, disk mowers, hayrakes, hay tedders, haybalers and bale wrappers. For grain harvest, reaper/grain harvesters, reaper-binders, and even combine harvesters are available, for transport, trailers with capacities from 0.5 to 5 plus ton cargoes are available. General mowing implements consist of lawn mowers, brush mowers, for snow removal, implements consist of snowblowers, power sweepers, and snow/dozer blades. Other implements include, chipper/shredders, log splitters, electrical generator, pressure washer, crimper-roller, fertilizer/salt/lime spreader and this confusion over, or perhaps just ignorance of the utility of 2-wheel tractors, persists even at research and institutional levels. Yet, when two-wheel tractors are included, Bangladesh and Sri Lanka are the most highly mechanized countries in south Asia in terms of area farmed using mechanized tillage. Two-wheel tractors are also common for agricultural use in the mountainous countries of Europe. The homegrown instances and the threads are discussed in subsequent sections. In 1910 Dr. Konrad von Meyenburg of Basel, Switzerland and he then licensed his patent to Siemens-Schuckertwerke of Berlin, Germany. Siemens an electrical manufacturer built their first two-wheel tractor with rotovator Bodenfräse using an electric motorized two-wheel tractor, the idea was quickly abandoned and Siemens began using two and four cycle single cylinder internal combustion engines to power their two-wheel tractors. Around 1932 Siemens sold off its cultivator division and focus on its electrical applications, mr. Eberhard Bungartz of Munich, Germany, a trailer manufacturer, purchased the division in 1934 with all patents, parts, and machinery, and he went into production using the Bungartz name. Starting after World War II, many countries in Europe started producing two-wheel tractors, in 2014, Italy had over 15 manufacturers of two-wheel tractors. This allowed much safer and more practical operation of a range of implements. Only very recently have any Asian manufacturers added this feature to their machines at all, others manufacturers now out of business were Energic and Labor
トラクターはベーラー(baler)あるいはモーア(mower)のような作業機(アタッチメント)にエンジンの動力を転送するPTOと呼ばれる機構を持っている。日本においては、農業の中心は稲作であるため、ロータリーと呼ばれる回転軸に、耕運用の爪を多数備え付けた物が主流である。ロータリーの利点として、耕運後の土の状態が平らになり、代掻きなどの作業が行いやすいという点が上げられる。また、日本においては畑作でもロータリーが広く使われており、世界でも珍しい状態となっている。
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
