Agricultural machinery is produced in various countries around the world. American manufacturers have proven themselves to be the most successful in this area. Among them is John Deere.
John Deere is a proprietary brand of the American corporation Deere & Company, which specializes in the production of agricultural equipment. The company's products include tractors, combines, cotton harvesters, packaging presses, sprayers, etc. The company's product range also includes equipment for construction, forestry, diesel engines and transmissions for heavy equipment. There is also a variety of products available for processing summer cottages.
The company's products are marked with a trademark - a green pennant with a yellow border, in the center of which is a yellow running deer. The company's slogan - "Nobody can run like a deer" - was created by copywriter Bob Wright, who used a play on words in it. In English, the word “deer” (“deer”) sounds the same as the surname of the company’s founder, John Deere. JCB 4CX
history of the company
The history of the brand began back in 1837, when blacksmith John Deere opened a store in Grand Detour (Illinois). His main products were cast steel plows, forks and shovels; he also repaired equipment. Even then, his tools were distinguished by their special quality - steel plows did not get dirty and did not wear out as quickly as the wooden and iron ones used by farmers.
However, plow production progressed slowly, and John Deere decided to break away from the then-traditional business model of making to order and began producing display implements. Thus, buyers saw ready-made product samples and could try them in action. This innovation had a positive effect on Dir's success in trade. The fame of his plows spread very quickly beyond Gran Detour.
In 1842, John Deere became a partner with Leonard Andrus, with whom he built a plow factory. The success of the enterprise forced Deere to build a new factory on his own in Moline (Illinois) in order to have access to the railroad and water communication along the Mississippi River.
In 1886, when the company was headed by his son, Charles Deere, after John's death, the company's products included a wide variety of agricultural equipment. In addition to plows, vans, seeders, and cultivators were produced.
In 1912, Deere & Company President William Butterworth (Charles' son-in-law), who succeeded Charles Deere after his death in 1907, turned to tractor production. At first, the company experimented with creating its own tractor models, the most successful of which was the all-wheel drive Dain. However, after the acquisition of the Waterloo Gasoline Engine Company in 1918, which produced the Waterloo Boy tractor at the facilities of Deere & Company, this particular model became the priority. It was subsequently introduced as the John Deere Model D.
By the 21st century, the company had expanded its production network to 27 countries on all continents. The products are popular and internationally recognized.
Current tractor series
Currently, the company presents tractors in six series.
The 6B series is distinguished by its remarkable appearance, reliability and versatility. The equipment is equipped with only the most necessary functions - nothing superfluous.

John Deere tractor series - 6B
One of the simplest series of John Deere tractors is 6B. Very easy to use. Characterized by its versatility, high performance and simple design. So, in principle, it can be easily repaired by the tractor owner himself.
A more powerful and complex series of 6D tractors.
These tractors developed from the 6003 series. They have a high percentage of productivity and are characterized by their durability. These tractors are stronger than their 6B series cousins, as they are capable of 130 hp. You will need such a tractor if you need to dry hay, do mowing along the road, or if you need a unit when cleaning a paddock. You can also safely use it to level driveways.
Tractor series John Deere - 6030 and John Deere - 6M
The 6030 series of tractors differs from previous series in increased power and durability. The power of these machines is about 150 hp. or 114 kW.
Another series of tractors from John Deere is the 6M. In terms of its characteristics, it is on par with the 6030 tractors. Equally effective in field and road conditions. Almost ideal for a simple agricultural business. Its increased power comes from the improved PowerTech E engine.
Other tractors are designed for more efficient work and larger tasks on the site. Among the versions of advanced tractors from John Deere, we can name the 7030, 8R and 8RT series. There is the 9R series, as well as the 9RT, which was formed on the basis of the above-mentioned engine version.
John Deere Series Tractor - 7030
The John Deere 7030 tractor is characterized by equally high efficiency both during field work and when transporting goods. The ergonomic and comfortable cabin will delight the driver, as will the new PowerTech Plus engine. The technical equipment of the tractor allows it to move at speeds of up to 50 km/h at low engine speeds. Tractor power - 195-213 hp. Such power will not consume much fuel at all. With increased speed, it consumes a minimum of fuel.
The 8R tractor will be needed by those who need to constantly work in the field from spring to autumn. Plow large areas of land with ease of management. Such tractors are equipped with a 9-liter PowerTech engine.
Below you can see the 8360R model:
The 9R and 9RT tractors are the most powerful tractors John Deere makes. They have power from 451 to 616 hp. They can handle almost any load. The series is equipped with an operator-friendly CommandArm control system. The exclusive AirCushion hitch is designed for high-quality tractor tracks.
The tractor's coupling mechanism can handle up to 9 tons of weight. Tractor models 9410, 9510R/RT, 9460R/RT, 9560R/RT come with four wheel sets and three track sets.
Fuel consumption of a John Deere tractor (John Deere) using the example of 8320R
We previously discussed fuel efficiency when talking about the 7030 tractor. Minimum energy costs with high power and torque.
Now let's look at the fuel efficiency of John Deere products using the 8320R tractor as an example. The first tractor in the 8R series was first introduced to the market in 2010 after being tested by the Nebraska Tractor Laboratory. In fact, the Nebraska laboratory is the only structure that provides reliable and reliable confirmation of the presented characteristics of manufactured tractors.
So, in 2009, John Deere released its new product - the 8320R tractor to replace the previously used 8030 model. During testing, the model with a power of 320 hp. has shown itself to be a machine that can easily crush its competitors thanks to more power and lower diesel fuel consumption than equipment from other companies.
To begin with, the tractor showed the result: 226 grams per kilowatt per hour with a power of 274.73 hp, taking into account the nominal engine speed.
During the testing process, the laboratory tried to create conditions as close as possible to those in which the tractor under test would be located. After the first test, a load was placed on the tractor's coupling mechanism as if it were pulling a plow or a loaded trailer.
The tractor achieved a consumption of 240 g/kWh with a power output of 186.66 horsepower.
This makes the 8320R the best heavy duty rural tractor on the market. At 75% of the tractor's full power, it saves 25% of the fuel that competing tractors would use.
The device of the John Deere tractor (John Deere)
Previously, we examined the capabilities of the John Deere 8320R tractor in terms of its capabilities with low diesel fuel consumption in comparison with the capabilities of models from other companies. They also talked a little about the engines and various parts that some of the tractors of this company are equipped with.
The 8R series became the basis for a new series called 7R. This is a row crop tractor. In other words, it is used after the land has already been plowed, everything has been planted and industrial, grain or vegetable crops need to be harvested. It is also possible to plow soft soils in a greenhouse or garden.
So, about the design of this tractor, although the 7R has evolved from the larger and more powerful version of the 8R, it has a smaller engine that produces power in the range of 200-280 hp. It was equipped with a 6.8 liter PowerTech PSX engine. It is used by the 7200R and 7215R models.
Models 7230R, 7260R, 7280R were equipped with a PowerTech PVX engine with a volume of 9 liters. Both engine types meet the maximum Tier 4 exhaust emission standards. 7R models have an automatic continuously variable transmission, thereby delivering more performance at lower engine speeds per minute.
The device also features a modern CommandView II driver's cabin, which is equipped with an electronic control device. The cabin is equipped with an on-board computer with a touch screen. The developers also improved the cabin suspension - it began to automatically correct itself taking into account the unevenness of the ground, although it can do this at the driver’s request.
