Deere & Company, the firm founded by John Deere, began to expand its range of John Deere equipment to include the tractor business in 1876. The Deere company briefly experimented with building its own tractor models, the most successful of which was the Dain all-wheel drive.
The Dain all-wheel drive was the first tractor produced by John Deere, and had only a single rear wheel. In 1911, Deere purchased the Dain Manufacturing Company of Ottumwa, Iowa. The next year, Deere decided to design its own tractor, and Dain founder, Joseph Dain Sr., was directed to design that tractor. After several prototypes, the design was finalized in 1917, and 100 production units were ordered. By 1919 when that production run was complete, Deere had purchased the Waterloo Boy Company. Although the Dain AWD was ahead of its time, with features such as a shift-on-the-fly transmission, Deere halted production in late 1919, partly because the cost of the Dain tractor was double that of the Waterloo Boy,[1] and partly because of the death of Dain Sr.
The predecessor of the Waterloo Boy came about in 1892. It was made by thresher-man John Froelich. It is called the "Froelich tractor". In March 1918, Deere & Company decided to continue its foray into the tractor business by purchasing the Waterloo Gasoline Engine Company which manufactured the popular Waterloo Boy tractor at its facilities in Waterloo, Iowa.
Deere & Company continued to sell tractors under the Waterloo Boy name until 1923.
Despite a rather severe farm economy depression at the time, Deere & Company management decided to build the Model D prototype in 1923, designed by Muir L. Frey (father of Ford Mustang designer Donald N. Frey).[2] The Deere Model D was produced from March 1, 1923, to July 3, 1953, the longest production span of all the two-cylinder John Deere tractors. Over 160,000 were made.[3]
The first Model D rode on steel wheels with a 6.5x (later 6.75x) two-cylinder hand-cranked engine rated 15to.[3] It was not, however, the first tractor to bear the Deere name; as a number of Deere experimental tractors, and the John Deere Dain all-wheel drive tractor (of which approximately 100 were produced during 1918 and 1919) had all carried the Deere name before the Model D.
By 1925, Deere & Company realized the standard Model D did not meet customers' needs for industrial applications. Steel wheels were not suitable for hard surfaces, and the gearing was too slow for safe road speeds. Solid rubber tires were added, and engineers fitted a 28 tooth sprocket to the final drive, giving a road speed of 4mph. The company replaced the 465abbr=onNaNabbr=on two-cylinder engine with a 501cid. In 1926, Deere & Company advertised the model as the "John Deere industrial tractor", with 40× rear wheels and 24x fronts with solid tires. This became known as the "DI". Options also included wheel weights.[4]
On June 20, 1928, the model designation was changed from "C" to "GP", to avoid confusion with the "D" when dealers were phoning in orders to the factory. "GP" stands for "general purpose". This new model GP had the same horsepower, engine displacement, weight, and three-speed transmission as the model C. The GP's first serial number was 200211. In 1930, the GP was updated with a 25hp, 339cid engine.
The John Deere Model GP was built in five distinct versions through the course of its production:
The John Deere Model A came off the assembly line in April 1934. The tractor was 25hp, was 309cid, and had a four-speed transmission. There were eight different model A variations. Some of these were tricycle, hi-crop, orchard, single front tire, and industrial models. The tricycle wheel design, patterned after that of the Farmall tractor, reduced steering effort, and greatly increased maneuverability. The Model B was introduced in June 1934. This tractor had a shorter frame than the Model A, but it was eventually lengthened so it could use some of the same equipment that the larger models A and G used. There were also eight different Model B tractor variations, the same as the larger Model A.
The much larger G model arrived in 1937. It was fitted with a 36hp, 425cid engine, and a four-speed transmission. Deere & Company publicized the G as a three-plow tractor, and it was built until 1941, when the GM (G, modernized) replaced it. The GM model was made from 1942 to 1947. The drawbar power increased to 38hp, and a new six-speed transmission was also added. The G model got a restyled front at this point, as did the other John Deere tractor models. The GM had electric starting and lighting added to its options. During its production time, the G tractor was available as a hi-crop, single front wheel, and styled.
Deere & Company made their first un-styled row crop tractor in 1929, to compete with the Farmall. It was a modified GP tractor, with adjustable rear axle track (distance between wheels on the same axle), and a narrow front end. In 1933, Deere & Company started experimenting with what would come to be known as the Model A. The new Model A went into production in 1934. The A launched John Deere into the row crop farming market. The A was by far the most popular two-cylinder tractor that Deere & Company produced. The next year the Model B was introduced. It was one third smaller than the A, which made it ideal for smaller farms. A few years later, the Model G was introduced in 1937. It remained un-styled for several more years than the A and B. The un-styled tractors launched Deere & Company into the row crop farming market which they are still a major part of today. The model designation was actually labeled on the support between the seat and the platform. Any other location is an incorrect restoration. This continued onto the styled tractors until 1947.
The Deere & Company very nearly went bankrupt in the Great Depression. Only a large order of tractors for the Soviet Union kept the company going.
In 1937, John Deere hired well known industrial designer Henry Dreyfuss from New York City to re-style Deere & Company's agricultural equipment, especially its tractors. In the fall of 1937, a John Deere tractor engineer was sent to New York to ask Dreyfuss to redesign the tractors. Legend has it that Dreyfuss was so intrigued by the project, that he took a train to Waterloo that very night. Dreyfuss learned to operate the tractors, and worked with them in the field to gain firsthand knowledge of the changes that needed to be made. The first two letter series tractors (the A and B) were the first to receive the new modern styling, and other models were added later. The Dreyfuss styling was intended to help Deere & Company compete with the forthcoming Farmall "letter series" of tractors, which, along with the Ford-Ferguson, were John Deere's largest competition at this time. Dreyfuss and the Waterloo engineers perfected the styled design that was used on all John Deere tractors, with only minor changes through to 1959.
The 1930s and 1940s saw a large number of different John Deere models emerge, as small farmer.s emerging from their Depression troubles increasingly turned from horses to tractors. Deere & Company's GM model was introduced in 1942, and was made until 1947. Engine power was increased to 38hp, and a new six-speed transmission was also added. The G model got a restyled front at this point, as did the other John Deere tractors models. The GM had electric start and lights added to its options. During its production time, the G tractor was available in hi-crop and single front wheel versions. The G was restyled in 1941, but did not start to roll off the assembly line until early 1942. Like the smaller A and B tractors, the G model had the six-speed transmission added to it. In 1946, the 1946 model "D" had a 501cid engine, which was enormous for the day. Two new additions to the tractor line, the M and R models, were also added.
After the models A and B got new styling, both tractors were given six-speed transmissions in late 1940. The A was 29hp out of a 321cid engine, while the smaller B was both 18hp23hp, reflecting the earlier and later updates between 1938 and 1946. The 14.84 Model H was given the Dreyfuss look from the time it was introduced in 1938. The H broke a fuel economy record when it was tested in Nebraska. This tractor also had three variations that came out in 1940–1941. The H tractor was 14.84hp out of a 90cid engine, and had a three-speed transmission. 1947, all models operator platforms were updated with, a cushioned seat, new steering cloumn, lights, battery, and electric starting which resulted in an inclosed flywheel.
In 1939, the restyled Model D appeared. The D was a 42hp tractor, and weighed 5300lb. Options available on this tractor included electric lighting and starting. In August 1940, Deere & Company introduced the new model LA which was followed by the model LI. The LA had a 77cid engine with 14 belt horsepower. The John Deere G tractor was restyled in 1941, but did not start to roll off the assembly line until early 1942. Like the smaller A and B tractors, the G model also had the six-speed transmission, but also featured electric lights and electric start.
In 1947, Deere & Company opened a new tractor factory in Dubuque, Iowa, built to produce the John Deere Model M. The M was created to address the increasing demand for small tractors, and compete with the increasingly popular Ford, and the smaller Farmall tractor models. The M was the second John Deere tractor to use a vertical two-cylinder engine, after the LA, but the first to with a square bore to stroke ratio of 4× 100.5abbr=onNaNabbr=on with a high row crop.
After years of testing, Deere & Company released its first proper diesel engined tractor in 1949, the Model R. The R was also the first John Deere tractor with a live independent power take-off (PTO) equipped with its own clutch. The R also incorporated live hydraulics. PowrTrol, as it was known, provided the operator the ability to lift equipment by the pull of a lever. A pump powered by the PTO clutch provided 1800abbr=onNaNabbr=on of hydraulic pressure to a lever controlled valve. At 45hp at the drawbar and 50hp at the belt, it was the most fuel-efficient tractor available at the time, and this combination of features resulted in over 21,000 being built. The Model R had a shipping weight of 7670lb. The R was equipped with two engines. The main engine is a two-cylinder, four-stroke, naturally-aspirated 416cid (5.75by bore and stroke), direct injected diesel engine, with a 16:1 compression ratio. The starting engine is also a John Deere two-cylinder, 26cid horizontally opposed gasoline engine. The starting or "pony" engine is electrically started by a six-volt electrical system, and is used to crank the main diesel engine. Testing results with various electrical starting systems for the diesel engine proved to be too bulky, requiring a 24- or 32-volt system. The design of the pony starter Model Rs allowed for hot exhaust gasses to preheat the intake air for the diesel engine, and a common liquid cooling system allowed the pony engine to warm the diesel engine block and head. This provided sufficient cold weather starting aids for the diesel engine that it would reliably run in sub-zero conditions. The R did have several teething problems, as this was Deere & Company's first production diesel engined tractor. Available as a standard tractor only, it did not have an adjustable front axle, nor did it have a three-point hitch. The engine was mainly an up-scaled gasoline engine from the Model D. The use of a thermosiphon cooling system, and the lack of a three-point bearing crankshaft proved inadequate for diesel engine compression ratios. The R was prone to overheating, and cracking the cylinder head. The lack of a center main bearing in the crankshaft allowed the crankshaft to flex when used as a stationary power-plant on the belt; this would lead to its failure. The live PTO was directed through two 45° bevel gears that proved too small to durably transmit the full torque of the engine. The tractor was fully serviceable at pulling larger equipment efficiently on large acre wheat-land farms.
During the 1950s, the R saw a series of upgrades in the models 80, 820, and 830. The 80 was produced for two years, and 3,500 were produced. It had new features, including power steering and dual hydraulics. It developed 68hp and weighed 8100lb. The 80 also corrected the other design flaws within the R, such as using a water pump and radiator pressure cap, and the addition of a center crankshaft main bearing.
The 820 and 830 were similar overall, but also differed in their sheet metal exteriors, fuel tank designs, and color schemes. The 720, was basically the same as the 70, except for the model number, and that the sides of the hood are painted John Deere yellow. The 720 was upgraded to the 730 for 1959. The 730 featured more contoured bodywork than the 720, and came with more ergonomic features for the operator. Although the 730 had a short production run, it became one of Deere & Company's most popular models. The 730 also featured power steering and 24-volt electric starter motor, instead of the V4 pony starter engine. The 730 was available in diesel, gasoline, and LPG, as well as in row crop tricycle, row crop wide front, standard tread, and hi crop wide front formats. The 730 is very popular with tractor pulling enthusiasts, because of its weight, power, and slow speed. The 730 was a 59hp tractor at the belt and 54hp at the drawbar.
After making more than million two-cylinder tractors, Deere & Company switched to four- and six-cylinder engines. Announcement of the change came after seven years of development, and forty million dollars in retooling.
In October 1959, the company showcased a new large 215hp four-wheel drive (4WD), called the 8010, on the Robert Ottilie Seed Farm north of Marshalltown, Iowa. It was shown during the largest farming field days event held in Iowa up to that time. Only one hundred 8010s were built, and 99 of those were rebuilt at the factory, and re-released as 8020s in 1960.
To introduce its new generation tractors to all of its dealers in a single day, Deere & Company chartered airplanes to fly more than 5,000 people to Dallas, Texas, on August 30, 1961. Deere & Company put their new tractors on display outside the Cotton Bowl, and inside Neiman Marcus. The day marked the release of a revolutionary line of farm tractors, with sleek new styling by Henry Dreyfuss, that would soon become the standard by which all other farm tractors would be measured.[5] These tractors were the 1010, 2010, 3010 and 4010.
These were soon followed by the model 5010 standard introduced in 1962. The 5010 was the first two-wheel drive to exceed 100hp at the PTO and drawbar. Designed for the western wheat-lands, the 5000 series was never available as a row crop model. In 1963, the 3010 and 4010 were replaced by the 3020 and 4020, both of which were offered with a powershift transmission designed by a former Ford employee. The 4020 is one of the most popular tractors Deere & Company has ever made. The year 1965 brought the 5020 standard, which was the industry's most powerful two-wheel-drive model, along with the 1020, 2020, and 54hp model 2510. By 1966, the 4020 accounted for 48% of all John Deere tractor sales.[6] Also that year, a row crop version of the 5020 was introduced.
In the late 1960s, Deere & Company pioneered the roll-over protection structure to protect the driver from injury in the event of a tractor roll-over. John Deere invited the competition to view a demonstration of its new Roll-Guard. Deere recommended that all tractors include this safety feature, and offered to share its design and test data with its competitors. Deere & Company also encouraged farmers to retro-fit their tractors with this safety feature, and offered roll guards at cost to farmers who wished to install them on their older new generation tractors.
In 1968, nine new models appeared: the 820, 920, 1120, 1520, 2120, 2520, 4000, 4520, WA-14, and WA-17. The WA-14 and WA-17 were articulated four-wheel-drive tractors, built by Wagner under a no compete clause, which extended to 5 years after deere dropped the line. thus resulting in wagner going bankrupt. The 4520 was Deere & Company's first turbocharged tractor. The 3020 and 4020 were updated with new features, and the 5020 model had a drawbar power increase to an industry leading 141hp. The 4000 was a high horsepower-to-weight tractor, designed to be a "runner" rather than a "lugger". The 4000 used the same engine as the popular 4020, but weighed almost 1000lb less. According to Deere & Company, the 4000 could, in the same amount of time, pull a four-bottom plow fast enough to cover the same acreage as a 4020 pulling a five-bottom plow. The John Deere 4000 was also an economy tractor, providing the same horsepower as the 4020, with fewer features and smaller rear axles.
During the 1970s, Deere & Company introduced 36 new models. In 1972, John Deere introduced the Generation II tractors. Generation II was characterized by the optional Sound-Guard body. This innovative cab was isolated from the tractor by large rubber bushings, which dampened vibrations, and the interior was insulated with foam to reduce noise, and protect the operator from extreme temperatures outside. A foam pad on the firewall and sheets of lead under the dash greatly reduced engine noise inside the cab. The Sound-Guard body also featured a rounded front windshield with an integrated door. The door post was in line with the exhaust and air intake pipes, which route through the hood for the best forward visibility possible. Fully integrated heating and air conditioning was standard equipment, and it also featured windshield wipers, a dome light, a red interior lamp to illuminate the gear shift levers and hydraulic controls during nighttime operation, and speakers for an optional AM/FM radio, which many farmers added because they found the cab so quiet they could actually hear it. When it was introduced, it was the quietest tractor cab in the industry, and a vast improvement over the aftermarket cabs that Deere & Company had previously retrofitted to its tractors.
The Generation II tractors also offered other innovative features not available on previous John Deere models, such as a Quad-Range transmission that improved on Deere's proven Synchro-Range transmission, by adding a high and low gears in each range, and Deere's new Perma-Clutch; a wet clutch that would last much longer, virtually the life of the tractor.
Deere & Company introduced at least 38 new tractors during the 1980s, during a time when over six other competitors merged, were sold, or went out of business altogether:
In what some industry watchers were calling Generation III, the year 1991 brought a glimpse of what Deere & Company tractors of the 1990s would be like. Eight new John Deere tractors were introduced in 1991, starting with the three 5000 Series tractors. These were the 40hp 5200, 50hp 5300, and 60hp 5400. Two new models, the 92hp 3055, and 100hp 3255 followed.
Deere & Company is manufacturing 5000 Series of tractors at Sanaswadi, Pune, in India; the range of products from India are listed below. Additionally, the paint schemes changed in 2007. In 2007, Deere & Company made some horsepower rating changes in otherwise unchanged machines. The 5103 came with a black engine and driveline prior to 2007, when they began painting the engine area all green. These are referred to as black belly's or green belly's. The black belly 5103 was rated at 50hp, while as is listed below the green belly 5103 was rated at 40hp.
For 1992 model year, Deere & Company introduced the 160hp 4560, the 175hp 4760, and 202hp 4960. They were nearly identical to the 4555, 4755, and 4955 they replaced, with the improvements being improved lighting and safety,[21] hood free of the air intake and exhaust pipe, which was moved to the right corner post of the cab on the 60 Series tractors, and an improved cab entry step with handrail.
In the fall of 1992, six totally new 6000 and 7000 Series tractors were introduced by Deere & Company;[22] the 62hp 6200, 75hp 6300, 85hp 6400, 110hp 7600, 125hp 7700, and 146hp 7800. Also the cabs were completely redesigned for better visibility and operator comfort; John Deere's new cabs were a significant improvement over the Sound Guard body which had set the industry standard for two decades.
The spring of 1993, Deere & Company introduced the four new 70 Series Power Plus 4WD models; these were the 250hp 8570, 300hp 8770, and a new model, the 350hp 8870. And the first 400hp tractor, the 8970. These tractors were equipped with an electronic power bulge that would kick in when tough field conditions were encountered. Later in the summer, the 3055 and 3255 were replaced with the 92hp 7200 and 100hp 7400.
1994 was a red letter year in tractor development for Deere & Company, because that year brought about the most revolutionary row crop tractors the industry had seen up to then. 1994 was the last year of the Sound Guard body from John Deere, with the last one built being a 2WD 4760 model. It was manufactured on 1994 May 25. This ended a 22-year run for Sound Guard tractors, that were widely regarded as the most successful tractors ever built.
1996 saw thirteen new tractors debuted at a big John Deere dealer meeting in New Mexico.
During the fall of 1998, Deere & Company had a 360hp prototype 9300T track tractor at at least three farm shows. During August 1999, the company had another dealer meeting in Moline, Illinois. It was here that the 360hp 9300T, and 425hp 9400T were revealed to their John Deere dealers. A 115hp 7510 with full four-wheel drive was added. As a result, the 7610 was uprated to 120hp, and 7710 up to 135hp. The 8000/8000T Series tractors were replaced with the 165hp 8110/8110T, 185hp 8210/8210T, 205hp 8310/8310T, and 235hp 8410/8410T. Caterpillar sued John Deere (Caterpillar, Inc. v. Deere Co.) for alleged patent infringement on the design of the track tensioning system for the 8000T/9000T tractors. Caterpillar won the initial case and John Deere appealed the decision. The United States District Court for the Northern District of Illinois issued a summary judgement on appeal, vacating the original decision. [23]
One thing the John Deere dealers in attendance at Columbus saw that did not appear at 'Deere.com' until March 2004 was the new 500hp 9620. The 9620 came after two of Deere & Company competitors introduced 500hp 4WDs.
In Columbus, Ohio, Deere & Company announced the replacement of the three larger 7000 TEN tractors; namely the 140hp 7720, 155hp 7820, and the new 170hp 7920; the 7610 was discontinued.
The Deere & Company annual dealer meeting was held in Omaha, Nebraska; the launches included:
In 2007, Deere & Company released thirty-two (32) new tractor models; the year began with the introduction of the 5603 and 5625, both these are 82hp, and are a further extension of the 5003 and 5025 Series tractors.
The Deere & Company big meeting was held in August 2007 in Cincinnati, Ohio; the John Deere dealers saw four new nursery and greenhouse tractors, which would not appear on the 'Deere.com' website until February 5, 2008; these would be the:
At the Cincinnati dealer meeting, the dealers also saw the regular 6030 / 7030, and the Premium 6030 Series tractors:
In early 2008, Deere & Company introduced another compact diesel engined tractor, the 27hp 3005, which is essentially an updated John Deere 870. Followed by the new 31 engine PTO 23.5hp 2720 later in the year.
On the back of the John Deere publication The Furrow (Summer 2008) is a signup for new equipment. Deere & Company had another dealer meeting in late July 2008, to introduce many new utility tractors. But the real announcement came with John Deere introducing a new worldwide numbering scheme for the entire range of compact and agricultural tractors.
From the 2008 model year range, Deere & Company nomenclature on the engine horsepower output for individual models will now be advertised in official literature and online using the metric system per the International Organization for Standardization (ISO) 97/68/EC standard for determining net rated engine drawbar power output; the metric horsepower value will be used in the model name.
In 2008, the first John Deere tractors to get the new naming scheme were the 5D, 5E, 5E Limited edition, and the 6D Series tractors. These tractors were introduced at the annual Deere & Company dealer meeting; this year's event was held in Denver, Colorado.
The biggest John Deere tractors in the new range were the 100hp140hp 6D models.
According to the 'Deere.com' website, Deere & Company introduced two new diesel engined 3E Series tractors. This pair of new 3E Series tractors is on page two of The Furrow, December 2008 edition. Both new 3E models would appear in early October 2008. These would be the 31hp25hp 3032E and 37hp30hp 3038E. The 3032E is powered by a 97abbr=onNaNabbr=on, while a 91cid supply's the power on the 3038E. ProMagazine.com reports that this pair is for house owners who want a tractor that could take on everyday jobs, some features are: diesel engine, twin touch pedals, hydrostatic transmission, standard 4WD, optional cruise control, power steering, a power take-off (PTO) that is electronically engaged.
On March 17, 2009, Deere.com announced the new 152hp 7530 Premium tractor.
During the week of August 13, 2009, the company had another big dealer meeting in Omaha, Nebraska, to introduce the new 8R/8RT row crop and track tractors to their dealers. On August 20, 2009, at Deere.com, a news release was posted on the 8R, 8RT, and two new 5105M specialty tractors. Six new green-and-yellow 8R row crop tractors 225hp 8225R, 245hp 8245R, 270hp 8270R, 295hp 8295R, 320hp 8320R, and the 345hp 8345R. PTO ratings are 181hp, 198hp, 220hp, 242hp, 263hp, and 284hp respectively. The 8225R is the only one available as a two-wheel-drive model. Optional IVT or Powershift transmissions. In John Deere nomenclature, the first number equals size, the next three numbers are the engine horsepower, and the letter at the end stands for capability. The six tractors range from 225hp345hp, with the 8345R being the most powerful row crop model on the market. Also shown to the dealers were the new 8RT rubber track tractor models. These three models are the 295hp 8295RT, 320hp 8320RT, and the 345hp 8345RT. The T at the end stands for tracks; other than that, the numbers in the 8RT Series are the same in their 8R counterparts. PTO horsepower for the three 8RT tractors are 239hp, 260hp, and 281hp respectively.
The 8RT models had their fuel capacity to 200usgal, and can come with track width up to 160inches. All nine 8R/8RT tractors are powered by the company's 548abbr=onNaNabbr=on PowerTech Plus six-cylinder diesel engine. Two other lesser known tractors were also introduced by the company are the 5105ML orchard and poultry tractors. The horsepower is 105hp engine and PTO 90hp. One version of the 5105ML comes configured to work in orchards and vineyards, while the other version is a low-profile tractor for work in poultry barns.
In August 2010, Deere & Company had another dealer meeting in Cincinnati, Ohio, to introduce still more tractors. This was confirmed at Deere.com on August 26, 2010, with the announcement of more new 8R/8RT Series tractors. The new models are 2011 model year tractors, with several improvements. These would be the 8235R, 8260R, 8285R, 8310R, 8335R, and 8360R wheel tractors, ranging from 235to rated engines. The PTO outputs are 192hp, 213hp, 234hp, 250hp, 276hp, and 296hp for the six tractors. Besides the six wheel tractors, three new 8RT track tractors would also be added. There would be the 310hp360hp rated engine 8310RT, 8335RT, and the 8360RT. Power-take off horsepower is 247hp, 268hp, and 288hp respectively. One of the major changes with these nine green-and-yellow tractors was the new PowerTech PSX 548cid dual turbocharged diesel. This is an Interim Tier 4 (IT4) diesel engine. On January 1, 2011, EPA Tier 4 regulations began, thus the new PowerTech diesel in these tractors. Despite their competitors going with SCR to counter this, John Deere uses exhaust gas recirculation (EGR). To tell these new 8R tractors apart from the earlier 2010 tractors, John Deere put new wrap-around lights up front. Also the model number has been moved close to the front just off the black grill on both sides. Another characteristic is the new large black muffler on the right corner of the cab. Other improvements engineered into these tractors are JDLink, ActiveCommand Steering (ACS), Infinitely Variable Transmission (IVT) AutoMode, GS3 CommandCenter, and the StarFire 3000 receiver.
In a 2010 October meeting in Florida, John Deere dealers were shown the new 1023E and 1026E sub compact tractors that the company announced in February 2011.
In 2018, John Deere had the following tractors:[24]
On June 15, 2020, the X9 combines were announced on John Deere's website. The X9 combines are currently available in two models: the X9 1000 and the X9 1100.
