About John Deere

John Deere is a major American manufacturer and supplier of equipment special purpose. The company has almost two centuries of history.

Of course, John Geer did not create the tractor right away (in historical sources the spelling of the surname “Ger” is sometimes found). His company began in 1837, when Illinois blacksmith John Deere, in response to farmers' complaints about the lack of a good plow for the heavy prairie soil, forged his own, which did the job perfectly. A year later, the blacksmith became an industrialist and began his own production. In 1842 he had already made a hundred plows.

By 1948, Deere had formed a partnership and moved to Mississippi. There his factory soon doubled its output. In 1876 the company registered its own trademark.

Since then, John Deere has come a long and difficult path from a local manufacturer of harrows and plows to a major global developer and seller of special equipment for various purposes.

Interesting: the demonstration to N. S. Khrushchev during his visit to the USA of the operation of the John Deere tractor became an incentive for the development in the USSR own car.

Advantages and disadvantages of tractors

Experts highlight the following advantages of John Deere equipment:

• high power and performance;
• tractor reliability;
• modern technologies, good technical equipment of machines;
• ease of operation on tractors, interior comfort.

The disadvantages include the high cost of basic kits and attachments, expensive spare parts and service, low maintainability in “home” conditions in case of breakdown. The latter is due to the fact that the structure of the John Deere tractor is quite complex and contains many high-tech components.

Approximate prices of John Deere tractors

Prices for 100 series lawn tractors start at 1,600 USD. The cost of the X350 in the company’s catalog is indicated at 3,199 USD.

Mini-tractors of family 1 are sold at prices starting from 12 thousand USD. Series 2 starts from 16 thousand USD, series 3 – from 17,300 USD, 4 – from 18 thousand, 5 – from 20 thousand USD.

The cost of equipment from older families is significantly higher. So, series 6 cars will cost 40-50 thousand USD, or more. Series 8 cars cost between 150-300 thousand USD in used condition, the cost of new ones is even higher. The latest models of the 9th series will cost the buyer 370-500 thousand USD or more if the equipment was used, the cost of new ones is from 500-600 thousand USD and more.

The price must be confirmed with the dealer or directly through the manufacturer.

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 full power tractor, 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 new series, which was 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 electronic device management. 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.

Advantages and disadvantages of John Deere tractor equipment

Operators confirm that the stated characteristics correspond to real requirements. By and large, this is:

• the ability to select a model with preset characteristics;
• long overhaul life of the main components and assemblies, including the power plant, transmission and chassis;
• a fairly developed service network, prompt delivery of ordered spare parts and consumables;
• comfortable working conditions for the tractor driver;
• a large selection of branded, productive trailers and attachments, compatibility with similar products from domestic and European manufacturers.

The list of shortcomings includes:

• high prices for the entire list of spare parts and consumables;
• service in remote regions is far from perfect;
• complexity self-repair equipment in the field and restoration of worn-out parts;
• low level of information support from service organizations, lack of materials for retraining and advanced training.

Storing a tractor fleet in heated garages is an unaffordable luxury for most organizations. Imported tractor equipment, including those produced by John Deere, have problems starting the engine in sub-zero temperatures.

Prices of new and used tractors

The cost of tractors of this brand in all respects corresponds to the performance characteristics of the entire model range. In the offered assortment, it is easy to choose a modification that combines the necessary parameters with an affordable price.

The funds invested in the purchase of the machine are many times compensated for by comfortable working conditions, trouble-free and long-term operation of all components and assemblies, economical consumption of fuel and lubricants and consumables.

Due to the unstable economy, the price range of zero-mileage John Deere tractors for small farms and utilities is not yet available, so many buyers are purchasing used equipment. The cost of a technically sound machine with a significant remainder of the assigned resource is approximately one and a half times lower.

The practice of operating John Deere products has shown that with qualified maintenance and proper use, a tractor purchased secondhand will exhaust the remainder of its assigned service life with a 20-30% excess. Thanks to the developed service network and the availability of a range of spare parts, downtime tractor equipment is reduced to a minimum.
