Zetor (since January 1, 2007, officially Zetor Tractors a.s.) is a Czech agricultural machinery manufacturer. It was founded in 1946. The company is based in Brno , Czech Republic. Since June 29, 2002, the only shareholder has been a Slovak company, HTC Holdings. The company manufactures tractors and tractor components ( engines or transmissions ).
122-626: Zetor was the first manufacturer to develop and produce tractor safety cabins . In its 70-year history, Zetor has sold over 1.3 million tractors. Currently, the Zetor portfolio includes six model ranges with power outputs ranging from 40 to 160 hp (30 to 120 kW). Abroad, Zetor is represented through seven affiliations in North America , the United Kingdom , France , Germany , Poland , Slovakia and India . In 2015, 86% of total production of
244-407: A trailer or machinery such as that used in agriculture , mining or construction . Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage , and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if
366-491: A 20 hp (15 kW) engine. In 1897, it was bought by Mr. Locke-King, the first recorded British tractor sale. That year, it won a Silver Medal from the Royal Agricultural Society of England . It later returned to the factory for a caterpillar track fitting. The first commercially successful light-weight petrol-powered general purpose tractor was built by Dan Albone , a British inventor in 1901. He filed for
488-445: A 42 hp (31 kW) four-cylinder engine, was manufactured from 1955 to 1960 and then, as the upgraded Zetor 50 version, until 1968. In 1952, Zetor moved to a new location within Brno , Líšeň, where all tractors have since been produced. In the late 1950s, ZETOR was the first to introduce the concept of using unified parts to produce tractors worldwide. The Unified Series I (UŘ I.)
610-504: A Ferguson-designed hydraulic hitch. In 1938 Ferguson entered into a collaboration with Henry Ford to produce the Ford-Ferguson 9N tractor . The three-point hitch soon became the favorite hitch attachment system among farmers around the world. This tractor model also included a rear Power Take Off (PTO) shaft that could be used to power three point hitch mounted implements such as sickle-bar mowers. In 1969, General Electric introduced
732-525: A field to haul a plow back and forth between them using a wire cable. In Britain Mann's and Garrett developed steam tractors for direct ploughing, but the heavy, wet soil of England meant that these designs were less economical than a team of horses. In the United States , where soil conditions permitted, steam tractors were used to direct-haul plows. Steam-powered agricultural engines remained in use well into
854-621: A jungle house, and a show arena. The new Canadian-themed area, Yukon Bay, opened in 2010. In 2010 the Hanover Zoo had over 1.6 million visitors. There is also the Sea Life Centre Hanover , which is the first tropical aquarium in Germany. Another point of interest is the Old Town . In the centre are the large Marktkirche (Church St. Georgii et Jacobi , preaching venue of the bishop of
976-488: A locomotive-style boiler with horizontal smoke tubes. A large flywheel was mounted on the crankshaft, and a stout leather belt was used to transfer the drive to the equipment being driven. In the 1850s, John Fowler used a Clayton & Shuttleworth portable engine to drive apparatus in the first public demonstrations of the application of cable haulage to cultivation. In parallel with the early portable engine development, many engineers attempted to make them self-propelled –
1098-410: A means to transfer power to another machine such as a baler , swather , or mower . Unless it functions solely by pulling it through or over the ground, a towed implement needs its own power source (such as a baler or combine with a separate engine) or else a means of transmitting power from the tractor to the mechanical operations of the equipment. Early tractors used belts or cables wrapped around
1220-411: A part of the tractor, almost as if it were attached by a fixed mount. Previously, when the implement hit an obstacle, the towing link broke or the tractor flipped over. Ferguson's idea was to combine a connection via two lower and one upper lift arms that were connected to a hydraulic lifting ram. The ram was, in turn, connected to the upper of the three links so the increased drag (as when a plough hits
1342-470: A patent on 15 February 1902 for his tractor design and then formed Ivel Agricultural Motors Limited. The other directors were Selwyn Edge , Charles Jarrott , John Hewitt and Lord Willoughby . He called his machine the Ivel Agricultural Motor; the word "tractor" came into common use after Hart-Parr created it. The Ivel Agricultural Motor was light, powerful and compact. It had one front wheel, with

#17328592645521464-542: A patent, Froelich started up the Waterloo Gasoline Engine Company and invested all of his assets. The venture was very unsuccessful, and by 1895 all was lost and he went out of business. Richard Hornsby & Sons are credited with producing and selling the first oil-engined tractor in Britain, invented by Herbert Akroyd Stuart . The Hornsby-Akroyd Patent Safety Oil Traction Engine was made in 1896 with
1586-445: A population of about 3,850,000 and is the 8th largest metropolitan area in Germany. Hanover passed a population of 100,000 in 1875, and Hanover's population has grown since 1946, when Hanover became the capital of Lower Saxony state and it grew rapidly in 1950s and 60s due to West German Wirtschaftswunder . This also saw the growth of a large migrant population, drawn largely from Turkey , Greece and Italy . Hanover has also one of

The Hanover Region , a district that surrounds the city of Hanover and cities like Langenhagen , Garbsen and Laatzen has a population of about 1,160,000 and is the largest District (Landkreis) in Germany. Hanover metropolitan region , which includes also cities like Braunschweig , Hildesheim and Göttingen , has
1830-677: A pretext to stage a nationwide pogrom known as Kristallnacht (9 November 1938). On that day, the synagogue of Hanover, designed in 1870 by Edwin Oppler in neo-romantic style, was burnt by the Nazis. In September 1941, through the "Action Lauterbacher" plan, a ghettoisation of the remaining Hanoverian Jewish families began. Even before the Wannsee Conference , on 15 December 1941, the first Jews from Hanover were deported to Riga . A total of 2,400 people were deported, and very few survived. During
1952-539: A range of transmissions. They also offered creeper gears in the CL model, up to three-stage PowerShift or PowerShuttle. The Forterra range introduced robust tractors equipped with four-cylinder Zetor engines, which were suitable for heavy-duty work in farming and forestry. The first models entered the market in 2008. In 2012, the range was extended by the Forterra HSX, with 30/30 transmission and electro-hydraulic reverser. In 2014,
2074-598: A reminder of the persecution of the Jews in Hanover. After the war a large group of Orthodox Jewish survivors of the nearby Bergen-Belsen concentration camp settled in Hanover. There was also a camp for Sinti and Romani people (see Romani Holocaust ), and dozens of forced labour subcamps of the Stalag XI-B prisoner-of-war camp for Allied POWs. As an important railway and road junction and production centre, Hanover
2196-529: A risk-mitigation standpoint because of what can go wrong if the operator makes a mistake – transmission damage is possible, and loss of vehicle control can occur if the tractor is towing a heavy load either uphill or downhill – something that tractors often do. Therefore, operator's manuals for most of these tractors state one must always stop the tractor before shifting. In newer designs, unsynchronized transmission designs were replaced with synchronization or with continuously variable transmissions (CVTs). Either
2318-403: A rock) caused the hydraulics to lift the implement until the obstacle was passed. Recently, Bobcat's patent on its front loader connection (inspired by these earlier systems) has expired, and compact tractors are now being outfitted with quick-connect attachments for their front-end loaders . In addition to towing an implement or supplying tractive power through the wheels, most tractors have
2440-433: A rollover risk depending on how the tractive torque was applied. The Fordson tractor was prone to roll backward due to an excessively short wheelbase. The linkage between the implement and the tractor usually had some slack which could lead to jerky starts and greater wear and tear on the tractor and the equipment. Drawbars were appropriate to the dawn of mechanization, because they were very simple in concept and because as
2562-467: A self-propelled one. The alteration was made by fitting a long driving chain between the crankshaft and the rear axle. The first half of the 1860s was a period of great experimentation but by the end of the decade the standard form of the traction engine had evolved and changed little over the next sixty years. It was widely adopted for agricultural use. The first tractors were steam-powered plowing engines . They were used in pairs, placed on either side of
SECTION 20
#17328592645522684-415: A separate, implement-mounted power source, which is almost never seen in modern farm equipment. It is also optional to get a front PTO as well when buying a new tractor. Virtually all modern tractors can also provide external hydraulic fluid and electrical power to the equipment they are towing, either by hoses or wires. Modern tractors have many electrical switches and levers in the cab for controlling
2806-535: A solid rubber tyre, and two large rear wheels like a modern tractor. The engine used water cooling, utilizing the thermo-syphon effect. It had one forward and one reverse gear. A pulley wheel on the left hand side allowed it to be used as a stationary engine , driving a wide range of agricultural machinery. The 1903 sale price was £300. His tractor won a medal at the Royal Agricultural Show , in 1903 and 1904. About 500 were built, and many were exported all over
2928-410: A synchronized manual transmission with enough available gear ratios (often achieved with dual ranges, high and low) or a CVT allow the engine speed to be matched to the desired final-drive speed, while keeping engine speed within the appropriate speed (as measured in rotations per minute or rpm) range for power generation (the working range) (whereas throttling back to achieve the desired final-drive speed
3050-421: A two-point "Fast Hitch", and John Deere had a power lift that was somewhat similar to the more flexible Ferguson invention. Once the patent protection expired on the three-point hitch, it became an industry standard. Almost every tractor today features Ferguson's three-point linkage or a derivative of it. This hitch allows for easy attachment and detachment of implements while allowing the implement to function as

Hanover Airport lies north of the city, in Langenhagen , and is Germany's ninth-busiest airport. The city's most notable institutes of higher education are
3416-454: Is a plug-in, powered by an electrical cable. Kubota is prototyping an autonomous electric tractor. Most older farm tractors use a manual transmission with several gear ratios , typically three to six, sometimes multiplied into two or three ranges. This arrangement provides a set of discrete ratios that, combined with the varying of the throttle, allow final-drive speeds from less than one up to about 25 miles per hour (40 km/h), with
3538-523: Is a trade-off that leaves the working range). The problems, solutions, and developments described here also describe the history of transmission evolution in semi-trailer trucks . The biggest difference is fleet turnover; whereas most of the old road tractors have long since been scrapped, many of the old farm tractors are still in use. Therefore, old transmission design and operation is primarily just of historical interest in trucking, whereas in farming it still often affects daily life. The power produced by

Hanover has an oceanic climate ( Köppen : Cfb ) independent of the isotherm. Although the city is not on a coastal location, the predominant air masses are still from the ocean, unlike other places further east or south-central Germany. The Hanover weather station has recorded
3782-474: Is debated. Hanover was a small village of ferrymen and fishermen that became a comparatively large town in the 13th century and received town privileges in 1241 because of its position at a natural crossroads. As overland travel was relatively difficult, its position on the upper navigable reaches of the river helped it grow from increasing trade. It was connected to the Hanseatic League city of Bremen by

The Kestner-Museum is located in the House of 5,000 windows . The museum is named after August Kestner and exhibits 6,000 years of applied art in four areas: Ancient cultures, ancient Egypt, applied art and a valuable collection of historic coins. The KUBUS
4148-443: Is the replacement of wheels or steel crawler-type tracks with flexible, steel-reinforced rubber tracks, usually powered by hydrostatic or completely hydraulic driving mechanisms. The configuration of these tractors bears little resemblance to the classic farm tractor design. The predecessors of modern tractors, traction engines, used steam engines for power. Since the turn of the 20th century, internal combustion engines have been
4270-551: Is via a quick hitch, which is attached to the three-point hitch. This enables a single person to attach an implement quicker and put the person in less danger when attaching the implement. The three-point hitch revolutionized farm tractors and their implements. While the Ferguson System was still under patent, other manufacturers developed new hitching systems to try to fend off some of Ferguson's competitive advantage. For example, International Harvester's Farmall tractors gained
4392-578: The 13th-largest city in Germany as well as the fourth-largest city in northern Germany after Berlin , Hamburg and Bremen . Hanover's urban area comprises the towns of Garbsen , Langenhagen and Laatzen and has a population of about 791,000 (2018). The Hanover Region has approximately 1.16 million inhabitants (2019) and is the largest in the Hanover–Braunschweig–Göttingen–Wolfsburg Metropolitan Region ,

In 1837, the personal union of the United Kingdom and Hanover ended because William IV 's heir in the United Kingdom was female ( Queen Victoria ). Hanover could be inherited only by male heirs. Thus, Hanover passed to William IV's brother, Ernest Augustus , and remained a kingdom until 1866, when it was annexed by
4880-789: The Elec-Trak , the first commercial, electric tractor (electric-powered garden tractor). The Elec-Trak was manufactured by General Electric until 1975. Electric tractors are manufactured by a German company, Fendt , and by US companies, Solectrac and Monarch Tractor. John Deere 's protoype electric tractor is a plug-in, powered by an electrical cable. Kubota is prototyping an autonomous electric tractor. Tractors can be generally classified by number of axles or wheels, with main categories of two-wheel tractors (single-axle tractors) and four-wheel tractors (two-axle tractors); more axles are possible but uncommon. Among four-wheel tractors (two-axle tractors), most are two-wheel drive (usually at

Though Hanover was expected to defeat Prussia at the Battle of Langensalza in 1866, Prussia employed Moltke the Elder's Kesselschlacht order of battle to and destroyed the Hanoverian Army. Thereafter the city of Hanover became the capital of the Prussian Province of Hanover . In 1872, the first horse railway was inaugurated, and in 1893, an electric tram
5856-707: The Seven Years' War , the Battle of Hastenbeck was fought near the city on 26 July 1757. The French army defeated the Hanoverian Army of Observation , which led to the city's occupation as part of the Invasion of Hanover . It was recaptured by Anglo-German forces, led by Ferdinand of Brunswick , the following year. After Napoleon imposed the Convention of Artlenburg (treaty of the Elbe) on 5 July 1803, about 35,000 French soldiers occupied Hanover. The convention also required disbanding

In addition to traditional markets such as Poland, Czech Republic, Slovakia and Germany, its products are also exported to the UK, France, Ireland and Lithuania . The name Zetor , which was later to become the name of the brand and which was used by the state Company to mark the tractors, was created by Rostislav Sapák, a member of the Czech Economic Department, in
8296-487: The early 19th century were portable engines – steam engines on wheels that could be used to drive mechanical farm machinery by way of a flexible belt. Richard Trevithick designed the first 'semi-portable' stationary steam engine for agricultural use, known as a "barn engine" in 1812, and it was used to drive a corn threshing machine. The truly portable engine was invented in 1839 by William Tuxford of Boston, Lincolnshire who started manufacture of an engine built around

8906-613: The first syllable, is applied to both the German and English spellings, which is different from German pronunciation, with stress on the second syllable and a long second vowel. The traditional English spelling is still used in historical contexts, especially when referring to the British House of Hanover . Hanover was founded in medieval times on the east bank of the Leine River. Its original name Honovere may mean 'high river bank', but that
9028-425: The following extreme values: The city of Hanover is divided into 13 boroughs ( Stadtbezirke ) and 53 quarters ( Stadtteile ). A selection of the 53 quarters: The current mayor of Hanover is Belit Onay of Alliance 90/The Greens , elected in 2019. The most recent mayoral election was held on 17 October 2019, with a runoff held on 10 November, and the results were as follows: The Hanover city council governs
9150-484: The fore-runners of the traction engine . In most cases this was achieved by fitting a sprocket on the end of the crankshaft, and running a chain from this to a larger sprocket on the rear axle. These experiments met with mixed success. The first proper traction engine , in the form recognisable today, was developed in 1859 when British engineer Thomas Aveling modified a Clayton & Shuttleworth portable engine , which had to be hauled from job to job by horses, into
9272-507: The forward power unit while the trailing unit is not steered separately. In the early 21st century, articulated or non-articulated, steerable multitrack tractors have largely supplanted the Caterpillar type for farm use. Larger types of modern farm tractors include articulated four-wheel or eight-wheel drive units with one or two power units which are hinged in the middle and steered by hydraulic clutches or pumps. A relatively recent development
9394-517: The history of Hanover, from the medieval settlement "Honovere" to the city of today. The museum focuses on the period from 1714 to 1834 when Hanover had a strong relationship with the British royal family of that period. With more than 4,000 members, the Kestnergesellschaft is the largest art society in Germany. The museum hosts exhibitions from classical modernist art to contemporary art. Emphasis
9516-431: The implement being semi-permanently attached with bolts or other mounting hardware. Usually, it was impractical to remove the implement and reinstall it on a day-to-day basis. As a result, the tractor was unavailable for other uses and dedicated to a single use for an appreciable period of time. An implement was generally mounted at the beginning of its season of use (such as tillage, planting or harvesting) and removed when
9638-518: The implement is mechanised. The word tractor was taken from Latin , being the agent noun of trahere "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term " traction motor" (1859). In the UK , Ireland , Australia , India , Spain , Argentina , Slovenia , Serbia , Croatia , the Netherlands , and Germany ,
9760-573: The largest Vietnamese communities in former West Germany due to its close distance to former East Germany . The Viên Giác pagoda in Mittelfeld, southern district of Hanover is the largest Vietnamese pagoda in Germany and one of the largest in Europe. Hanover is one of the liveable cities due to its good location and good population size. It is the fifth-largest city in the Low German dialect area after Hamburg, Dortmund , Essen and Bremen. Hanover
9882-531: The lower speeds used for working the land and the highest speed used on the road. Slow, controllable speeds are necessary for most of the operations performed with a tractor. They help give the farmer a larger degree of control in certain situations, such as field work. When travelling on public roads, the slow operating speeds can cause problems, such as long queues or tailbacks, which can delay or annoy motorists in cars and trucks. These motorists are responsible for being duly careful around farm tractors and sharing
10004-539: The marking of the tractor related to the approximate power of the engine in horsepower, e.g. 72, 80, 121, 162, etc. The next two numbers denoted powered axles, e.g. 72 11 (Zetor with approximate power of 72 hp (54 kW) without front-wheel drive). In 2015, at the Agritechnica exhibition in Hanover , Zetor introduced the design concept "Zetor by Pininfarina ". The concept was applied to all products and model ranges of
10126-509: The medium-power class are appreciated for easy operation and service. The Proxima range entered the market in 2004. It is a universal farming tractor employing Zetor four-cylinder engines. They could be used in conjunction with farming machines, industrial adaptors and in farming transport. They were mostly used in farming, forestry and community service. Zetor manufactured three types: Proxima CL, proxima GP, and Proxima HS, with power outputs ranging from 80 to 120 hp (60–89 kW), with
10248-790: The most varied collection of orchids in Europe. Some points of interest are the Tropical House , the Cactus House , the Canary House and the Orchid House , and free-flying birds and butterflies. Near the entrance to the Berggarten is the historic Library Pavillon . The Mausoleum of the Guelphs is also in the Berggarten. Like the Great Garden, the Berggarten also consists of several parts, for example
10370-458: The multitude of different functions available on the tractor. Some modern farm tractors retain a traditional manual transmission ; increasingly they have hydraulically driven powershift transmissions and CVT, which vastly simplify operation. Those with powershift transmissions have identical pedal arrangements on the floor for the operator to actuate, replacing a clutch pedal on the far left with an inching pedal that cuts off hydraulic flow to
10492-460: The norm. The first three-point hitches were experimented with in 1917. After Harry Ferguson applied for a British patent for his three-point hitch in 1926, they became popular. A three-point attachment of the implement to the tractor is the simplest and the only statically determinate way of joining two bodies in engineering. The Ferguson-Brown Company produced the Model A Ferguson-Brown tractor with
10614-450: The operator more automobile-like control over the speed of a mobile tractor in any operation. Hanover Hanover ( / ˈ h æ n oʊ v ər , - n ə v -/ , HAN -oh-vər, HAN -ə-vər ; German : Hannover [haˈnoːfɐ] ; Low German : Hannober ) is the capital and largest city of the German state of Lower Saxony . Its 535,932 (2021) population makes it
10736-415: The operator to engage the clutch to shift between gears. This mode of use is inherently unsuited to some of the work tractors do, and has been circumvented in various ways over the years. For existing unsynchronized tractors, the methods of circumvention are double clutching or power-shifting, both of which require the operator to rely on skill to speed-match the gears while shifting, and are undesirable from
10858-406: The power set-up reapplied (as in cable-drawn plowing systems used in early steam tractor operations). Modern tractors use a power take-off (PTO) shaft to provide rotary power to machinery that may be stationary or pulled. The PTO shaft generally is at the rear of the tractor, and can be connected to an implement that is either towed by a drawbar or a three-point hitch. This eliminates the need for
10980-481: The power source of choice. Between 1900 and 1960, gasoline was the predominant fuel, with kerosene (the Rumely Oil Pull was the most notable of this kind)being a common alternative. Generally, one engine could burn any of those, although cold starting was easiest on gasoline. Often, a small auxiliary fuel tank was available to hold gasoline for cold starting and warm-up, while the main fuel tank held whatever fuel
11102-410: The prototype of the forthcoming "Zetor by Pininfarina" tractors. Part of the museum is also a fan shop. Zetor provides a wide range of original spare parts to ensure long-lasting performance and compatibility for their tractors. Tractor A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque ) at slow speeds, for the purposes of hauling
11224-548: The range was extended by the Forterra HD, with a power output of 147 horsepower (110 kW) and electronic hydraulic regulation. For a long time, Zetor did not produce a powerful six-cylinder tractor. One was launched in 2015, when the unveiling of the Zetor Crystal. The name "Crystal" refers to the legendary tractors produced by Zetor from 1969 to the 1980s. In that period, over 45,000 Crystal tractors were sold. The new Crystal
11346-425: The rear ); but many are two-wheel drive with front wheel assist, four-wheel drive (often with articulated steering), or track crawler (with steel or rubber tracks). The classic farm tractor is a simple open vehicle , with two very large driving wheels on an axle below a single seat (the seat and steering wheel consequently are in the center), and the engine in front of the driver, with two steerable wheels below
11468-548: The road with them, but many shirk this responsibility, so various ways to minimize the interaction or minimize the speed differential are employed where feasible. Some countries (for example the Netherlands ) employ a road sign on some roads that means "no farm tractors". Some modern tractors, such as the JCB Fastrac, are now capable of much higher road speeds of around 50 mph (80 km/h). Older tractors usually have unsynchronized transmission designs, which often require
11590-441: The season ended. The drawbar system was virtually the exclusive method of attaching implements (other than direct attachment to the tractor) before Harry Ferguson developed the three-point hitch . Equipment attached to the three-point hitch can be raised or lowered hydraulically with a control lever. The equipment attached to the three-point hitch is usually completely supported by the tractor. Another way to attach an implement
11712-514: The second world war, Petrolium based fuel was scarce in many European nations. So they resorted to using wood gasifires on every vehicle, including tractors. In some countries such as Germany, biodiesel is often used. Some other biofuels such as straight vegetable oil are also being used by some farmers. Prototype battery powered electric tractors are being developed by a German company, Fendt , and by two US companies, Solectrac and Monarch Tractor. John Deere 's protoype electric tractor
11834-516: The spring of 1946. The name is formed of the syllable Zet (the spelling of the letter Z in the alphabet, the first letter of the name of the Arms Factory “Zbrojovka”) and the suffix –or from the word tractor . It also relates to the phrase " farming tractor " in Czech : "ZEmědělský trakTOR" (other cryptonyms for the name are also possible). The history of Zetor starts in 1946 when the first tractor
11956-557: The state-owned enterprise faced bankruptcy. In June 2002, HTC Holdings of Slovakia became the owner of Zetor. The new owners invested money to stabilise and restructure the enterprise. Zetor produces six tractor model ranges: Zetor Utilix, Zetor Hortus, Zetor Major, Zetor Proxima, Zetor Forterra, and Zetor Crystal. The new Utilix and Hortus lineups were introduced in the first quarter of 2018. New tractors are small and light, equipped with 4-cylinder engines with power outputs of between 43 and 67 hp (32 and 50 kW). Zetor Major range
12078-696: The tank factory M.N.H. Maschinenfabrik Niedersachsen (Badenstedt). Residential areas were also targeted, and more than 6,000 civilians were killed by the Allied bombing raids. More than 90% of the city centre was destroyed in a total of 88 bombing raids. After the war, the Aegidienkirche was not rebuilt and its ruins were left as a war memorial. Today around 25 % of the city consists of buildings from before 1950. The Allied ground advance into Germany reached Hanover in April 1945. The US 84th Infantry Division captured
12200-544: The time. While the earlier, heavier tractors were initially very successful, it became increasingly apparent at this time that the weight of a large supporting frame was less efficient than lighter designs. Henry Ford introduced a light-weight, mass-produced design which largely displaced the heavier designs. Some companies halfheartedly followed suit with mediocre designs, as if to disprove the concept, but they were largely unsuccessful in that endeavor. While unpopular at first, these gasoline-powered machines began to catch on in
12322-499: The tractor replaced the horse, existing horse-drawn implements usually already had running gear. As the history of mechanization progressed, the advantages of other hitching systems became apparent, leading to new developments (see below). Depending on the function for which a tractor is used, though, the drawbar is still one of the usual means of attaching an implement to a tractor (see photo at left). Some tractor manufacturers produced matching equipment that could be directly mounted on
12444-401: The tractor via a drawbar . The classic drawbar is simply a steel bar attached to the tractor (or in some cases, as in the early Fordsons, cast as part of the rear transmission housing) to which the hitch of the implement was attached with a pin or by a loop and clevis . The implement could be readily attached and removed, allowing the tractor to be used for other purposes on a daily basis. If
12566-431: The tractor was equipped with a swinging drawbar, then it could be set at the center or offset from center to allow the tractor to run outside the path of the implement. The drawbar system necessitated the implement having its own running gear (usually wheels) and in the case of a plow, chisel cultivator or harrow, some sort of lift mechanism to raise it out of the ground at turns or for transport. Drawbars necessarily posed
12688-399: The tractor. Examples included front-end loaders, belly mowers, row crop cultivators, corn pickers and corn planters. In most cases, these fixed mounts were proprietary and unique to each make of tractor, so an implement produced by John Deere, for example, could not be attached to a Minneapolis Moline tractor. Another disadvantage was mounting usually required some time and labor, resulting in
12810-437: The use of turning brake pedals and separate track clutches operated by levers rather than a steering wheel. Four-wheel drive tractors began to appear in the 1960s. Some four-wheel drive tractors have the standard "two large, two small" configuration typical of smaller tractors, while some have four large, powered wheels. The larger tractors are typically an articulated, center-hinged design steered by hydraulic cylinders that move
12932-516: The war seven concentration camps were constructed in Hanover, in which many Jews were confined, but also Polish , French and Russian women. Of the approximately 4,800 Jews who had lived in Hanover in 1938, fewer than 100 were still in the city when troops of the United States Army arrived on 10 April 1945 to occupy Hanover at the end of the war. Today, a memorial at the Opera Square is
13054-445: The word "tractor" usually means "farm tractor", and the use of the word "tractor" to mean other types of vehicles is familiar to the vehicle trade, but unfamiliar to much of the general public. In Canada and the US , the word may also refer to the road tractor portion of a tractor trailer truck , but also usually refers to the piece of farm equipment. The first powered farm implements in
13176-463: The world. The Hanover Zoo received the Park Scout Award for the fourth year running in 2009–10, placing it among the best zoos in Germany. The zoo consists of several theme areas: Sambesi, Meyers Farm, Gorilla-Mountain, Jungle-Palace, and Mullewapp. Some smaller areas are Australia, the wooded area for wolves, and the so-called swimming area with many seabirds. There is also a tropical house,
13298-571: The world. It provides 496,000 square metres (5.34 million square feet) of covered indoor space, 58,000 square metres (620 thousand square feet) of open-air space, 27 halls and pavilions. Many of the Exhibition Centre's halls are architectural highlights. Furthermore, it offers the Convention Center with its 35 function rooms, glassed-in areas between halls, grassy park-like recreation zones and its own heliport. Two important sights on
13420-504: The world. The original engine was made by Payne & Co. of Coventry . After 1906, French Aster engines were used. The first successful American tractor was built by Charles W. Hart and Charles H. Parr . They developed a two-cylinder gasoline engine and set up their business in Charles City, Iowa . In 1903, the firm built 15 tractors. Their 14,000 pounds (6,400 kg) #3 is the oldest surviving internal combustion engine tractor in
13542-637: The world. Hanover hosts annual commercial trade fairs such as the Hanover Fair and up to 2018 the CeBIT . The IAA Commercial Vehicles show takes place every two years. It is the world's leading trade show for transport, logistics and mobility. Every year Hanover hosts the Schützenfest Hanover , the world's largest marksmen's festival, and the Oktoberfest Hanover . The name of the city may derive from
13664-521: Was George I Louis , who acceded to the British throne in 1714. The last British monarch who reigned in Hanover was William IV . Semi-Salic law , which required succession by the male line if possible, forbade the accession of Queen Victoria in Hanover. As a male-line descendant of George I, Queen Victoria was herself a member of the House of Hanover. Her descendants, however, bore her husband's titular name of Saxe-Coburg-Gotha . Three kings of Great Britain, or
13786-820: Was a major target for strategic bombing during World War II , including the Oil Campaign . Targets included the AFA ( Stöcken ), the Deurag-Nerag refinery ( Misburg ), the Continental plants ( Vahrenwald and Limmer ), the United light metal works (VLW) in Ricklingen and Laatzen (today Hanover fairground ), the Hanover/Limmer rubber reclamation plant , the Hanomag factory ( Linden ) and
13908-474: Was equipped with a six-cylinder engine, having a power output of from 144 to 163 hp (107–122 kW). The engines were had 24 valves and common-rail fuel injection. The transmission offered 30 forward and 30 reverse gears. The operation of the tractor was made easier by three-stage PowerShift, PowerShuttle and PowerClutch, with the clutch button incorporated into the gear-shifting lever. The Unified Series used new coding. The first two or three numbers of
14030-604: Was installed. A local newspaper, the Hanoverscher Kurier , was published in Hanover at this time. After 1937 the lord mayor and the state commissioners of Hanover were members of the NSDAP (Nazi party). A large Jewish population then existed in Hanover. In October 1938, 484 Hanoverian Jews of Polish origin were expelled to Poland, including the Grynszpan family . However, Poland refused to accept them, leaving them stranded at
14152-450: Was launched in 1992, with models 7520, 7540, 8520, 8540, 9520, 9540 and 10540, having power outputs of between 82 and 103 hp (61 and 77 kW), badged as Model 92. In 1994, the 7320 Turbo and 7340 Turbo models extended the range. In 1997, the production of models 3321 super-7341 super turbo was launched, badged Model 97. The turn of the millennium was a period of significant change for the Zetor brand. It could have disappeared, because
14274-472: Was launched in the early 2002. It was a simple tractor with a power output of 80 hp (60 kW), appreciated for its reliability and low operating costs. In 2015, the Major range was extended by a new type Major 60 with a power output of 61 hp (45 kW). In late 2016, the company launched new Major HS, which offered higher comfort while retaining low operation costs. Tractors of the Major range included in
14396-475: Was launched, with the models 2011, 3011 and 4011, with two, three and four-cylinder engines. In 1968, the Unified Series II (UŘ II) was launched. It included many innovative features for the time, e.g. the world's first safety cabin with rollover protection system, mounted on vibration isolators. The new cabin also helped to reduce noise in the cabin to below 85 dB. Thanks to these innovative procedures,
14518-851: Was most convenient or least expensive for the particular farmer. In the United Kingdom, a gasoline-kerosene engine is known as a petrol-paraffin engine . Dieselisation gained momentum starting in the 1960s, and modern farm tractors usually employ diesel engines , which range in power output from 18 to 575 horsepower (15 to 480 kW). Size and output are dependent on application, with smaller tractors used for lawn mowing , landscaping, orchard work, and truck farming , and larger tractors for vast fields of wheat, corn, soy, and other bulk crops. Liquefied petroleum gas (LPG) or propane also have been used as tractor fuels, but require special pressurized fuel tanks and filling equipment and produced less power, so are less prevalent in most markets. Most are confined for inside work due to their clean burning. During
14640-424: Was produced by Zbrojovka Brno , branded Zetor 25. The Zetor trademark was registered in the same year, and mass production of Zetor tractors started on 7 August 1946. By 1947, about 3400 had been produced. In 1948, the Zetor 15 was approved for production, and it was manufactured until 1949. The Zetor 25 A and 25K were manufactured until 1961 and 158,570 were produced, of which 97,000 were exported. The Zetor 35, with
14762-519: Was reconstructed and reopened in 2013. Among its points of interest is the Grotto, with the interior designed by French artist Niki de Saint Phalle . The Great Garden consists of several parts and features Europe's tallest garden fountain. The historic Garden Theatre has hosted the musicals of the German rock musician Heinz Rudolf Kunze . Also at Herrenhausen, the Berggarten is a botanical garden with
14884-721: Was the site of EXPO 2000 fair. Some points of interest are the Planet M. , the former German Pavillon , some nations' vacant pavilions, the Expowale , the EXPO-Plaza and the EXPO-Gardens (Parc Agricole, EXPO-Park South and the Gardens of change). The fairground can be reached by the Exponale , one of the largest pedestrian bridges in Europe. The Hanover Fairground is the largest exhibition centre in
