[edit] Waterloo Boy
The predecessor of Waterloo Boy came about in 1892. It was made by thresherman John Froelich. It is called the Froelich tractor. Scale Models of Dyersville, Iowa made a 1/16th scale toy tractor of this 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. Before John Deere bought The Waterloo company the Model R was built with production commencing in 194. Over 8,000 of this Model R were built. This model was 25 belt hp out of a 465 cubic inch displacement engine. There was also four styles of the Model R. These were the styles F, G, H and L, M. These had different mechanical changes to them. In late 1917 the Model N was revealed. This model had the same sized engine and horsepower as the R Model. The Model N had a 2-speed transmission while the R Model was only a one speed. It was this model which was the first tractor to be tested at the University of Nebraska in 1920. Some Models N and R wound up in England and became known as Overtime Models. Waterloo Boy 1912-1924.R Stlyes A amd M 1914-17.John Deere Waterloo Boy N Styles A-C 1918-22.In 1912 the company started their search into possibly making a tractor to enter the tractor business.Joe Dain Jr. thru John Deere produced 100 12-24hp All-Wheel drive machines.Deere's board authorized a 2.35 million dollar purchase to Waterloo Gasoline Engine Company in March 1918.This Waterloo company successfully made three of 2-cylinder tractors namely the L and LA and the very successful Model R.The Model R was the base of all John Deere tractors for close to 50 years.Dain All-Wheel Drive 24 belt hp,382cid,2-speed transmission and 4,600lbs.Waterloo Boy Model R-25 belt hp,465cid,1 speed with a weight of 6,000lbs.Over 8,000 of this tractor was built and was built in 12 different styles ranging from A to M.Styled A,B,C and D had changes in engine size.The Model R Styles E,F and G had their engine bore increased from 5.50 to 6 inches.It wasn't until the Styled H that production on this model was increased dramatically.
[edit] John Deere Model D
Despite the severe farm economy depression, Deere management decided to build a final John Deere D prototype in 1923. The John 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. The first Model D rode on steel wheels with a 6.5x7.0 inch (later 6.75 x 7.0 inch) two-cylinder hand-cranked engine. It was not however the first tractor to bear the John 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 through 1919) had all carried the Deere name before the D. The 1930's and 1940's saw a large number of different John Deere Tractor models, as small farming turned from horses to mechanical tractors. The 1938 "L" sold for just $465. new. The 1946 "D" had a 465 cubic inch engine, enormous for the day. One of the first Model Ds was the Spoker built from 1923-25. The 2-speed model from 1926-1933 and the 3-speed model from 1934-39 followed. The 1923 was 27-belt hp with a 482 cid engine while the 1926 model acquired a 501 cid engine while the hp was upped to 42. In July of 1930 there was 50 Model s built of which 10 were crawler tractors and the serial numbers are from 107001 to 107048. The Model D starting in 1934 got a new 3-speed transmission. The first serial number of this tractor is 30401 which came in 1924 while the last came in 1963 with 191670. Another version of this tractor was the DI industrial tractor which came painted yellow.
[edit] John Deere GP Tractor
Another new tractor followed which followed the D was the Model C. This came with a 312 cid engine which put out 20hp and came equipped with 3-speed transmission. The Model C was made during the years 1927-28 serial numbers were #1 to 200110. Walter Keller of Forest Junction, Wisconsin owns a Model C tractor. On Hune (sicsic) 20. 1928 this tractor had ist name changed from the Model to the Model GP. GP stands for General Purpose. Walter Keller also owns one of these tractors too. This new model GP had the same hp engine displacement, weight and 3-speed transmission as the C Model. This C tractor's first serial number was 200211 but was changed to 400000 in late 1928. The GP tractors made from 1930 on got a 6.00 X 6.00 inch engine at 950 rpm, 25hp and 339 cubic inch displacement. A GPO model was made from 1931-35. GPO stand for General Purpose Orchard. Competition in the form of International Harvester's Farmall John Deere decided there was a need for a smaller tractor that could serve this market and the row-crop farmer's requirements. The John Deere Model GP was built in five distinct versions through the course of its production:
- The standard-front GP, or John Deere Standard, built from March 1928 to February 1935
John Deere Model M Tractor - The John Deere two-wheel tricycle-front GP, or GP-Tricycle, of which twenty-three units were built between August 1928 and April 1929
- The John Deere GP Wide-Tread, or GPWT, built from November 1929 to November 1933
- The John Deere GP Wide-Tread Series P, a GPWT with narrowed rear tread width designed to suit potato rows, built between January and August 1930
- The John Deere General Purpose Orchard tractor, or John Deere GPO from April 1931 to April 1935 GP. There were also other GPWT variations namely the P and the GPO-L. The GPO-Ls were crawler tractors which was fitted with undercarriages from Lindeman Brothers in Yakima,Washington.
From 1932 thru 1938 the Models A.B,G,Y,62 and L all appeared. The first Model A came off the assembly line in April 1934.The tractor was 25hp,was 309 cid and ahd a 4-speed transmission. There were 8 different Model A variations. Some of these were tricycle, Hi-Crop, orchard, single front tire and industrial models. In the following year 1933 the prototype of the smaller model B was developed. The Model B started rolling of the assembly line in June 1934. This tractor came acompanied with a shorter frame then the Model A which was eventually lengthened so it could use some of the same equipment that the larger Models A and G used. There was also 8 different Model B tractor variations as there was with the larger Model A. The much larger G Model came about in 1937 and came accompied with a 4125. cid engine, a 4-speed transmission and about 36hp. John Deere publicized the G as a 3-plow tractor and was built until 1941 when the GM came along. GM stands for G Modernized. These models were made from 1942-47. The horsespower was increased to 38 and a new 6-speed transmission was also added. The G Model got a newly styled front at this point in time as did the other John Deere tractors up and down the line. The GM had starting and lighting that was both electric added to it options. During its production time the G tractor was available as a hi-crop, single front wheel and styled.
[edit] John Deere Model M
In 1947 John Deere opened a new tractor factory in Dubuque, Iowa, built to produce The John Deere M. The John Deere M tractor was created to address the increasing demand for small tractors and to compete with the increasingly popular Ford and Ferguson Tractors. It was the first Deere tractor to use a vertical 2-cylinder engine, with a square bore and stroke of 4.0 x 4.0 inches.
The 1930's and 1940's saw a large number of different John Deere Tractor models, as small farming turned from horses to mechanical tractors.
[edit] John Deere model 62, L, LA, LI
The 1938 "L" sold for just $465. new, and was designed to replace the last working horse on the farm, and was also designed to be able to fit into the back of a pickup truck. The 62,L,Y.LI and LA was made from 1936 to 1946. The Y Model was a run of 26 prototype tractors during which there was serial numbers issued for these. The 1936 first appeared in 1936 and onlly 24 came off of the assembly line. A year later in 1937 the model 62 was built.One of these Model 62 was at the Ohio 2-cylinder booth a The 2007 Ohio Farm Science Review.Off of the company's assembly line 79 Models 62 were built in 1937.Durirng the summer this Model 62 morphed into L tractor which was unstyled at the time.The L Model from 1937-38 was 10.42 hp which ame from a 57 cid engine. In 1938 from New York City John Deeere hired well known designer Henry Dreyfuss to give styling not omly to the green and yellow tractors but up and down their equipment line. The first two letter series tractors namely the A and the B got new modern styling.Both tractors were given a 6-speed transmission in late 1940.The A was 29hp out of a 321 cid engine while the smaller B was both 18 and 23hp reflecting the earlier and later updates between 1938 and 46. In 1939 on the heels of the A and B being styled came the Model D which also received modern styling to.This Model D was 42hp and weighed 5,300lbs.A apir of options that was added to this tractor was electric lighting and starting which paralleld the G. The G got styling in 1941 but did not start to roll off the assembly line until early 1942. Like the smaller A/B tractors the G Model also had the 6-speed transmission added to it.The 14.84 Model H did come with this new modern styling from the time it was introduced in 1938.The H broke a fuel ecomony record when it got tested in Nebraska.This tractor also had 3 variations that came out ion 1940-41. The H tractor was 14.84 hp out of a 90 cid engine and had a 3-speed transmission.Starting with SN 625,000 the very small L tractor got new modern styling to. In August 1940 John Deere introduced the new Model LA which was followed by the Model LI. The Model Ls were 10hp out of 66cid engine.The LA had a 77 cid engine which 14 belt hp.From the A,B,G,D got improvements between 1947-53.Two new additions to the tractor line namely the M and the R Models were also added.
The 1946 "D" had a 501 cubic inch engine, enormous for the day.
[edit] John Deere Model R, 80, 820, 830
After years of testing John Deere released its first diesel tractor in 1949. The John Deere R was also the first Deere tractor with a live independent PTO with its own clutch. At 55hp, it was the most fuel efficient tractor at the time. It had a ship weight of 7670lb with a total of 21,000 built. During the 1950's the R was upgraded to become the models 80, 820 and 830. The 80 was produced for 2 years and 3500 were produced. It had upgrades such as power steering and dual hydraulics. It developed 68 hp. and weight 8100lb. The 820 and 830 are almost the same tractor sheet metal is different and fuel was a little different other then that they are the same.
[edit] New Generation of Power
After making more than 1 1/4 million Two-cylinder tractors, John Deere switched to four- and six-cylinder engines. Announcement of the change came after seven years of development and forty million dollars in retooling. In 1959 the company showed in Marshalltown, Iowa a big 150hp 4WD called the 8010.[1][2]
To introduce the new tractors to all of its dealers in a single day, the company chartered planes to fly more than 5,000 persons to Dallas, Texas, on Aug. 30, 1960. The day would mark the release of a line of farm tractors that would soon evolve into the standard all other farm tractors would be measured by.[3]
The original New Generation tractors are the 1010, 2010, 3010 and 4010. These were followed by the model 5010 standard introduced in 1962.The is tractor was never available as a row crop model. The 5010 was the first two-wheel drive to be over 100 hp at the PTO and drawbar. In 1963 the 3010 and the 4010 were replaced by the 3020 and the 4020. The year 1965 brought the 5020 standard which was the industry's most powerful two-wheel drive model. Also in 1965 the 1020, 2020 and the 54hp 2510 was added. Sales of the 4020 in 1966 accounted for 48% of all John Deere tractor sales.[4] In 1966 the row crop version of the 5020 was made available to the farming community. Also in 1966 John Deere pioneered the Roll-Gard protection frame to protect the farmer from roll over while in the field.7 new models were introduced in 1968. These were the 820, 1020, 2520, 4000. 4520 (John Deere's first turbocharged tractor) and a pair of 4WDS called the WA-14 and the WA-17.The 3020 and the 4020 were updated with new features. The 5020 was boosted to an industry leading 141hp.
During the 1970s,John Deere introduced 36 new models starting in 1970 and ending in 1979.The year 1970 the 116hp 4320,135 4620 and the 146hp 7020.The following year 1971 the 60hp 2030,175hp 6030 and the 7520 also at 175hp were introduced.On Saturday August 19th,1972 John Deere dealers held an open house to usher in Generation 2.The four new tractors were the 8-hp 4030,100hp 4230,125hp 4430 and the 150hp 4630.There were billed as Sound Idea tractors because of their innovative Sound Guard Body operators enclosure.The year 1973 would bring forth the final New generation utility tractors.There were the 35hp 830,45hp 1530 and 70hp 2630.The first two Generation 2 four-wheel drives appeared in 1974 in the 215hp 8430 and the 275hp 8630.In 1975 the initial Generation 2 utility tractor were introduced.These were the 40hp 2040,50hp 2240,60hp 2440 and the 70hp 2640. A new 80hp addition to the long green line called the 2840 came to light in late 1976."Seven in 77" was the result in the year for 1977. The companies first compact diesels were introduced in the 22hp 850 and 27hp 950.Other then that the big news was what John Deere called "The New Iron Horses" with more horses and more iron.These were the 90hp 4040,110hp 4240,130 4440,156 4640 and the 180hp 4840.The following year brought the 215hp 8440 and the 275hp 8640. In late 1979 a third diesel compact was added.This would be the 33hp 1050. Five new utility tractors would be added at the same time.These were the 41hp 2040, 50hp 2240, 60hp 2440, 70hp 2640 and the 81hp 2940. These five new models had a black stripe on both sides of the tractor near the front with the top of the hood being flatter then their predecessors. John Deere introduced it least 38 new tractor during the 1980s during a time when it least 3 other competitors merged, were sold or went out of business altogether. Two new small compact diesel tractors were added in 1981.These were the 14.5hp 650 and 18hp 750.
Three new 4WDs came to market in the fall of 1981. These were the 225hp 8450, 290hp 8650 and the big 370hp 8850. The 8850 came with the company's biggest engine, the 955 cubic inch V-8. Besides the 8850 the JD844 wheel loader and the 990 hydraulic excavator were the only other John Deere products to get this V-8.Also according to Wayne Broehl's 1984 book John Deere's Company a larger 4WD tractor then the 8850 was supposed to appear but never did.In 1982 11 new 50 series tractors from 40 up to 192.99hp. The 40hp 1250,25hp2150,55hp 2350,65hp 2550,75hp 2750,85hp 2950, 100hp 4050, 120hp 4250, 140hp 4450, 165hp 4650 and the 192.99hp 4850. From the 2150 to the 4850 got another industry leading innovation in the Castor.Action mechanical front wheel drive which provided 20 percent more pulling power.Like the front tires of a motor grader this Castor/Action MFWD had the front tires lean to give greater turning radius.When teated in Nebraska the 4850 was the most fuel efficient tractor ever tested over 60hp.The following year 1983 brought in the final two 50 Series tractors namely the 50hp 1450 and the 60hp 1650.A 4020 shadow namely the 95hp 3150 came about in 1985.This was the first John Deere row crop tractor to have MFWD as standard equipment. Three new diesel compacts came to light in 1986. These were the 16hp 655, 20hp 755, 24hp 855 and the 900HC. The 900HC was offset like the 2-cylinder M and was for niche markets. The 655,755 and the 855 all had a hydrostatic drive transmission. The 2355, 2555, 2755 and the 2955 were featured as price fighter tractors in 1986 with less features. The following year 1987 John Deere brought out six new models in the 45hp 2155, 55hp 2355, 65hp 2555, 75hp 2755, 85hp 2955 and the 96hp 3155. In a October 1988 dealer meeting in Denver, Colorado the new 235hp 8560, 300hp 8760 and the 370ho 8960 were introduced. In early 1989 in Palm Springs, California six new 55 Series tractors were shown to dealers. These were the 105hp 4055, 120hp 4255, 140hp 4455, 156hp 4555, 177hp 4755 and the 202hp 4955. The 4555 was a entirely brand new model which was the same size as the 4640. This same year brought the 70 Series gear driven compact diesels. These were the 18hp 670, 24hp 770, 28hp 870, 33hp 970 and the 38hp 1070.
In some industry watchers were calling Generation 3 the year 1991 brought a glimpse of the 1990s would be like in John Deere tractors. Eight new tractors were introduced in 1991 starting with the three 5000 Series tractors.These were the 40hp 5200, 50hp 5300 and the 60hp 5400. A new model the 92hp 3055 and 100hp 3255 followed. But what the company called "Fined Tuned Perfection" otherwise know as the 60 Series tractors. These were the 156hp 4560, 177hp 4760 and the 202hp 4960. In the fall of 1992 six totally new 6000/7000 Series tractors were shown. These six tractors were the 62hp 6200, 75hp 6300, 85hp 6400, 110hp 7600, 125hp 7700 and the 146hp 7800. The spring of 1993 the four new 70 Series Power Plus 4WDs were introduced. These were the 250hp 8570, 300hp 8770 and a new model the 350hp 8870 and the first 400hp tractor the 8970. These tractor were equipped with a electronic power bulge that would kick in when tough field conditions were encountered. Later in the summer the 3055 and the 3255 were replaced with the 92hp 7200 and the 100hp 7400. 1994 was one of those red letter years in tractor development for John Deere because that year brought about the most revolutionary row crop tractors the industry had seen up to then. The new 8000 Series tractors were introduced with state-of-the-art 21st Century features. The 160hp 8100, 180 8200, 200hp 8300 and 225hp 8400. These four 8000 Series tractors were so far ahead that it would be another 4 years until a competitor had tractors that were similar to them. One lone utility tractor the 73hp 5500 was added in the fall of 1995. In a big dealer meeting in New Mexico the company debuted 13 new tractors. First all of the 7000 Series tractors were replaced the five 7000 TEN Series tractors. These were the 95hp 7210, 105hp 7410, 115hp 7610, 130hp 7710 and the 150hp 7810. But the big news came with the 8000T Series rubber belted track tractors. There were the 8100T, 8200T, 8300T and the 8400T. These built upon the 8000 Series wheeled tractors. The 70 Series tractors were replaced by the four 9000 Series tractors at 260, 310, 360 and 425hp. These were the 9100, 9200, 9300 and the 9400. 1997 brought seven new tractors, three in the Advantage Series and four in the 5000 TEN series models. The three advantage models were the 85hp 6405, 95hp 6605 and the 105hp 7405. The 45hp 5210, 55hp 5310, 65hp 5410 and the 75hp 5510 represent the 5000 TEN tractors. The spring of 1998 revealed the four 6000 TEN tractors. These were the 65hp 6110, 72hp 6210, 80hp 6310 and the 90hp 6410. Another new addition to the long green line in 1998 was the six 4000 Series compact diesel tractors. These were the 20hp 4100, 21.5hp 4200, 32hp 4300, 36hp 4400, 39hp 4500, and the 43hp 4600. A Advantage Series 30hp 790 compact diesel tractor was added to round things out. During the fall of 1998 John Deere had a 360hp prototype 9300T track tractor at it least three farm shows. During August of 1999 the company had another dealer meeting in Moline, Illinois. It was here that the 360hp 930T and the 425hp 9400T were revealed to their dealers. A 115hp 7510 that came with full four wheel drive was added. As a result the 7710 was kicked up to the 120hp and the 7710 up to 135hp. The 8000/8000T Series tractors were replaced with the 165hp 8110/8110T, 185hp 8210/8210T, 205hp 8310/8310T and the 235hp 8410/8410T.
The year 2000 was not an active year for new John Deere tractor introductions but did yield the 48hp 4700. But the year 2001 produced 32 new green and yellow tractors. Starting with the 40hp 990 Advantage Series compact diesel tractor this was only the beginning. Two new 5005 Series Advantage were also added. These were the 45hp 5105 and the 53hp 5205.
Early in 2001 the 5020 Series utility tractors was introduced. These were the 45hp 5220, 55hp 5320, 65hp 5420 and the 75hp 5520. But the big news for John Deere came in August 2001 in a dealer meeting in Albuquerque, New Mexico where 24 new tractors from 65 to 450hp were introduced. Breaking things down these were the 6003, 6020, 8020/8020T, 9020 and 9020T Series tractors. These were the 85hp 6403, 95hp 6603, 65hp 6120, 72hp 6220, 80hp 6320, 90hp 6420 in the smaller 6000 Series tractors. In the row crop tractor the ten models were the 170hp 8120/8120T, 190hp 8220/8220T, 215hp 8320/8320T, 235hp 8420/8420T and the 256hp 8520/8520T. As has been the case since 1996 John Deere has been the only company to offer row crop tractors in both wheel and rubber tracks. The 9000 Series 4WD were replaced with the 280hp 9120, 325hp 9220, 375hp 9320/9320T, 425hp 9420/9420T and the largest JD tractor in history up to that point the 450hp 9520/9520T. The 8020/9020 tractors got features like Independent Link Suspension and ActiveSeat to give the farmer a more comfortable and productive day in the field. Nine new 4000 TEN Series tractors came on in early 2002. These were from 18-48hp and were the 21hp 4110, 24hp 4115, 18hp 4010, 20hp 4115, 28hp 4210, 32hp 4310, 35hp 4410, 39hp 4510, 44hp 4610 and the 48hp 4710. Later in 2002 the smaller 7020 Series tractors debuted. These went from 95 to 125 hp and were the 95hp 7220, 105hp 7320, 115hp 7420 and the 125hp 7520.Also added were the 6015 Series which were the 72hp 6215, 85hp 6415, 95hp 6615 and the 105hp 6715. In early 2003 a IVT transmission was added to the options that could come with the 7710 and the 7810 tractors. A new 17hp 2210 compact diesel tractor was also added. Three new 5003 tractors were added in the summer of 2003. These were the 44hp 5103, 53hp 5230 and the 64hp 5403. It was during August that the company had another big dealer meeting in Columbus, Ohio. One thing the dealers in attendance saw that did not appear at Deere.com until March 2004 was the new 500hp 9620. The 9620 came on the heels of two of their competitors also introducing 500hp 4WDs.
