The tractor is prepared for the AutoTrac navigation system, which provides the most accurate +/- 3-10 cm boundaries of the run and makes it possible to work even at night and map the terrain. Additional installation of GreenStar equipment is required. Such a tractor will become not just the pearl of any technology park, but also the main “workhorse”, without which you can hardly imagine the work process. At the same time, it can be compared with the Kirovets K-700 tractor.

About Deere and Company Corporation

Deere&Company is a transnational engineering corporation headquartered in the city of Moline, in the US state of Illinois. Manufactures agricultural, industrial, logging tractors, trailed and attached equipment for them; combines; construction, gardening, snow removal equipment. As for agricultural equipment, it is the largest manufacturer in the world.

The company was named in honor of its founder (in 1837, an American blacksmith and inventor, and in the future industrialist, John Deere, opened his business in Moline). Throughout the 19th and early 20th centuries, Deere & Company produced steel plows, cultivators, seeders and other agricultural equipment.

The first John Deere tractor was assembled in 1918, after the company purchased a tractor. Soon it was tractors for agriculture for a long time, one might say “forever”, that became the main specialization of the corporation. The traditional green and yellow colors of Deer technology have long been well known throughout the world.

The company has ancient ties with our country. The first delivery of John Deere brand agricultural equipment to Russia was made back in 1880. The company's specialists also established trade with the new Russia: in the period 1923-1932, the RSFSR purchased several thousand tractors of this brand annually. In our time, assembly plants for John Deere tractors and combines were opened in the Moscow and Orenburg regions, and the chairman of the board of directors and executive director of the company, Samuel Allen, personally met with Vladimir Putin in 2010.

Not only assembly plants, but also full production cycle plants owned by Deere and Company operate all over the world: in the USA and Canada, European countries, India and, of course, China. Deere & Company's "North American Distribution Center", which is located in Rock Island, Illinois, this gigantic warehouse of products, spreads over an area of ​​246 thousand square meters and is located in the 4th place on the list of the largest buildings and structures on the planet (by their area directly on earth).

Place of the tractor in the plant's model range. Model features

The John Deere-8430 tractors were produced from 2005 to 2009, as part of the 8030 series of energy-rich universal row-crop tractors. This series included four models: 8230 - 250 hp; 8330 – 280 hp; 8340 – 305 hp and 8530 – 330 hp. Currently, they have been replaced by a new generation of powerful Deere tractors - the 8R series. It consists of heavy tractors models 8270R, 8295R, 8320R, 8335R, 8345R, 8370R, also differing in engine power, and their RT tracked versions.

The high versatility of the John Deere-8430 is achieved through successful aggregation with popular tillage implements, plows and seeders, and high-quality and efficient hydraulics.

The undoubted advantages of this model include its saturation with advanced technologies, high power combined with fuel efficiency and operational efficiency, and versatility. Among the innovative technologies used in John Deere 8430 are: electronic fuel injection control; satellite positioning system in the Precision Agriculture automatic control complex; telematic system for remote monitoring of the operation of the tractor and its systems.

The tractor is prepared for a special navigation system “Auto-Trac”, which guarantees the most accurate (+/- 3-10 cm) boundaries of the run and makes it possible to operate uninterruptedly, including in the dark, with terrain mapping. This will require additional installation of GreenStar equipment.

Namely, there are several options for signal accuracy:

• The SF1 system is in the basic configuration, the accuracy from pass to pass is about 30 cm (15 minutes from pass to pass); the rest are additional options:
• SF2 system – accuracy from pass to pass ±10 cm (15 minutes from pass to pass);
• StarFire RTK system – real-time kinematics with sub-2 cm accuracy (within 10 km of base station and 68% of the time).

These technologies help increase productivity, reduce the area of ​​mutual overlap of adjacent passages, reducing the cost of diesel fuel and other components of production costs. In addition, GreenStar guidance systems allow the operator to pay closer attention to the attachment and monitor its performance.

John Deere 8430 tractor engine

The tractor is equipped with a 9-liter four-stroke diesel engine “John Deere Power Tech Plus” (“PE 6068B”). This is an in-line 6-cylinder 24-valve engine with a turbocharging system and intercooling of charge air, variable geometry and liquid cooling. Direct fuel injection and removal of combustion products are provided by 4 valves on each cylinder.

The John Deere Power Tech Plus engine is equipped with a Common Rail direct fuel injection system, manufactured by . This power unit is also equipped with an “Auto-Prime” automatic fuel pumping system.

This motor has an accurate and precise response to changing loads. The Power Tech Plus engine only needs to drop 500 rpm to produce maximum torque. Thanks to this, the increase in torque is accelerated by 35 percent. The reaction time to load changes becomes shorter, as a result of which the performance of the power unit increases.

Engine parameters "Power Tech Plus" in numbers:

• Rated power. (EC 97/98) - 305 horsepower, or 225 kilowatts.
• Maximum torque – 1028 N.m.
• Torque reserve – 35%.
• Constant power range – 600 rpm (1500 – 2100 rpm).
• Cylinder diameter – 118 mm, piston stroke – 136 mm.
• Compression ratio: 16.3:1.

Among other features of the John Deere-8430 tractor engine:

• The high-pressure rail (HP-CR) fuel system provides immediate response to changing loads for additional fuel savings.
• The air-cooled intercooler improves engine performance and efficiency.
• An electronic fuel pump that automatically bleeds air after replacing fuel filters reduces downtime.
• A cooling fan equipped with a viscous coupling and an improved “Vari-Cool” fan drive also help save fuel.
• The dry air filter has an inlet port on the cab support.
• Separate injection pumps.
• Fuel tank cooler.

Device and control

It is worth noting that the John Deere 8430 tractor differs from other models in its separate layout. It is thanks to this technology that it is possible to balance the weight as accurately as possible and distribute it throughout the entire structure. The engine is located in the front, which gives a significant advantage when driving even on damp ground.

Each buyer has the opportunity to independently choose one of the two proposed variations of the gearbox.

1. The first model has a sixteen-speed manual transmission. It shows pretty good results, even under the most extreme loads. This box is provided as standard. It is reliable, so it can serve its owner faithfully for many years. Gear shifts very smoothly. It is thanks to this that you can maintain speed in the range from 2 to 43 kilometers per hour. You can choose the most optimal transmission option if the load on the power unit is quite impressive. It is worth noting that in those moments when the load on the tractor changes, gears are switched automatically in order to maximize the performance of the equipment.

2. The second type is a continuously variable Auto Pwr type gearbox. The driver simply needs to select the speed of movement, and the tractor will independently maintain its position. Due to the fact that the system automatically reacts to changing loads, the tractor is quite easy to operate in any weather conditions. This box costs more than the standard version, but shows much better results in testing.

Thanks to the fact that the developers have integrated innovative cooling technology, it is possible to significantly reduce fuel consumption without losing rated power. Air flows are directed in such a way as not to damage the plants planted in the fields.

Thanks to the many years of experience of the developers, operating this tractor model is quite simple. The steering wheel is equipped with a power steering wheel, which significantly reduces the load when turning. The driver has a special monitor in the cab, which displays all the tractor parameters while driving. This allows you to fully control the entire process of driving and operation of the equipment.

Transmission of the John Deere-8430 tractor

The design of the John Deere-8430 tractor provides two types of gearboxes: “Automatic Power Shift” - an automatic step-by-step manual transmission; “Auto Power” is an automatic continuously variable hydrostatic-mechanical transmission. Both transmission options allow the operator to move off smoothly and reach maximum speed without using the clutch at all.

The first option, a 16-speed transmission, was developed by specialists based on the “Power Shift” system that appeared in 1994. Thanks to the integrated electronics and closed-loop gear shifting, gear shifts occur at a smooth rhythm.

This gearbox has sufficient strength to operate under sudden and high-torque loads, while maintaining the speed of response to control input and the reliability of gear shifting. When engine power is reduced or the load on the tractor changes, gear shifts occur automatically, within the selected range. In total - 16 forward and 5 reverse gears.

The continuously variable Auto Power gearbox, unlike the first version of the gearbox, was not included in the standard equipment of the John Deere-8430 tractor and was offered as an additional option. The operator only needs to select the required speed in the range from 0 to 42 km/h. (1.8 – 17 km/h – for reverse). Gear changes are easy and smooth.

There is a special “Power Zero” function designed to hold the tractor in place in case of braking on a slope. This gearbox option has a positive effect on the vehicle’s cross-country ability due to its immediate response to changing loads. It operates in four modes - manual, PTO, high traction and low traction control, economical transport mode. However, this transmission is very expensive and has a complex design.

Device

John Deere 8430 has a separate layout. Thanks to the front engine position, it is possible to achieve a good distribution of the tractor's ballast.

The American manufacturer offers the consumer to choose one of two gearboxes:

1. The 16-speed Automatic PowerShift manual transmission operates reliably even under heavy loads and complex work. This transmission is installed in the initial configuration of the John Deere 8430. This type of gearbox is distinguished by significant strength, smooth gear shifting and quick response to control input. The 16-speed Automatic PowerShift allows you to travel in a speed range of 2-42 km/h. This gearbox also allows you to set the optimal gear taking into account the engine load. When the engine power is reduced or the load on the tractor changes, gear shifts occur automatically (within the selected range);
2. Stepless AutoPwr is used for optimal operation. In this case, the operator selects only the desired speed (0-42 km/h). Gear changes are easy and smooth. The Power Zero feature keeps the tractor in place even when braking on a slope. The AutoPwr gearbox significantly improves the vehicle's maneuverability due to its quick response to changing loads. The disadvantage of this transmission is its higher cost and complex design. The basic package of the John Deere 8430 does not include the AutoPwr gearbox and is offered as an option.

The advanced cooling system and improved Vari-Cool fan drive reduce power consumption and provide significant fuel savings. At the same time, the direction of the air flows was changed so that they did not affect the plants and soil.

The MFWD front drive axle allows the front wheels of the vehicle to be doubled. An optional “ILS” front post with independent suspension and self-leveling is available on the John Deere 8430. The tractor's hydraulic system is based on an adjustable pump of the "Closed System" category.

Price of new and used John Deere 8430

The new John Deere 8430 will cost 5.3-5.5 million rubles. The cost of used tractors of this model starts from 3.7 million rubles.

Analogs

Analogues of the John Deere 8430 are the foreign tractors Case Magnum MX 300 and New Holland T 8040 and the domestic Kirovets 700.

Suspension, chassis, axles, brakes

The John Deere 8430 tractors are equipped with an independent lever-articulated suspension "ILS", automatically adjustable. Independent front axle suspension "ILS" provides maximum increase in power transfer to the ground, for consistently high performance, even when working on very uneven terrain. Suspension system - hydro-pneumatic, constant action, with automatic leveling, automatic load compensation and active traction geometry forces for three-point hitch implements.

The rear axle on the 8030 series can have an axle with a length of 2438 mm. To install single rear wheels, an axle of 2438 mm is provided on the rear axle of the tractor, and an axle with a length of 3002 mm is provided for installing double wheels.

The front steered axle is also a drive axle. Torque is supplied to the front-wheel drive at all gearbox speeds in the following three modes:

• forced connection;
• automatic – when changing the parameters of the road surface;
• braking optimization – activated when both brake pedals are pressed.

Tires of sizes “800/70 R38” and “600/70 R30” were used.

The brakes on this tractor are multi-disc. They work separately on the rear wheels, and are installed on the shaft axis between the differential and the final drive. They are controlled hydraulically, duplication occurs through a mechanical drive.

general characteristics

John Deere 8430 is called the best tractor for processing large fields

. The unit allows you to perform all work, from sowing to harvesting.

Reliable assembly, high-quality parts and high traction power allowed the 8030 line to become popular in large agricultural complexes. Good performance makes it possible to easily carry out work on areas of 1 hectare or more.

Model 8430 has become especially popular in the market of Eastern European countries. It allows you to perform functions in feed production, growing various crops and is used for transporting cargo. Such a wide functionality of the tractor is achieved thanks to a wide range of attachments.

Hydraulic system, PTO, linkage

The hydraulic system of the John Deere 8430 tractors is equipped with a load-sensing system based on an adjustable pump. Thanks to the new hydraulic pump with a capacity of 161 l/min, high speed transmission of oil flows to the equipment is ensured. Hydraulics type - closed center, PFC.

The hydraulic system holds 36 liters, or 54.9 liters with the auxiliary reservoir. The feed pump produces 120 liters per minute. Total flow: 166.5 l/min; 227.1 l/min (additional option).

The three-point rear hitch is electro-hydraulic, with full electronic control of lower link traction, hitch shock absorption, and external fender-mounted switches.

Hitch load capacity – 7847 kg; or 8300 kg (additional option). The maximum lifting capacity on hooks is 10,788 kg (105.8 kN). The OECD load capacity at 610 mm is 9519 kg (93.35 kN).

The rear power take-off shaft is independent, multi-disc type, with independent oil cooling, blocking and braking is carried out by an electro-hydraulic system. PTO type – 1000 rpm, 20 spline 45 mm shaft, or 2-speed. Does not require disassembly of the gearbox. 1000 rpm and 540 rpm - with 45 and 35 mm shafts.

Device Features

1. John Deere 8430R is one of the most popular models on the Eastern European market. The machine has support for mounted options intended for use in feed production and crop production, and for performing transport and lifting tasks. Thus, we are talking about popular tillage implements, plows and seeders, which are indispensable in agriculture. The tractor has great potential, largely due to its high power and excellent traction characteristics. Thus, the six-cylinder John Deere PowerTech Plus diesel unit with a displacement of 9 liters, a power of 305 horsepower and a torque of over 1000 N/m is responsible for performance. Turbocharging technology allows you to increase power to 330 horsepower. In this case, the maximum revolutions per minute will be 2200 rpm. In addition, the power unit is equipped with Common Rail fuel injection, which is involved in the uniform distribution of the combustible mixture throughout the combustion chamber. Thus, the developers managed to achieve higher dynamic characteristics, reduced toxicity and increased efficiency. In addition, let’s pay attention to the electric starter, which allows the engine to start confidently in any weather. Due to this, the machine is well adapted to frosty conditions - for example, in Siberia. Here we will also add a pre-heater, which also ensures effective starting in sub-zero temperatures. And in extremely hot weather, the cooling system works to prevent the engine from overheating.
2. The John Deere 8430 tractor is equipped with an AutoPWR transmission with intelligent gear shifting. The box has endless virtual gears that operate very smoothly and provide high elasticity. The gearbox operates silently, without any jerking or twitching when shifting to a lower or higher gear. The transmission operates quietly, as it makes no noise or vibration. Of course, this had a positive effect on comfort. In the box, you can activate one of two modes responsible for forward and reverse movement. It is noteworthy that the gearbox is well adapted to the high power and traction characteristics of the engine, and allows you to unleash the full potential of the internal combustion engine.
3. In addition to the synchronized operation of the internal combustion engine and gearbox, high tractor performance was achieved using a hydraulic pump, which has a throughput capacity of up to 227 liters per minute. In addition, we will also add an independent power take-off, which doubles the efficiency of the main gearbox. The power take-off shaft, otherwise known as the PTO, can be adjusted to speeds from 540 to 1000 rpm. In maximum mode, the three-point mounted implement's lifting capacity will exceed 8.3 tons, which is a decent result for an entry-level tractor.
4. The off-road capabilities of the tractor deserve special attention. Thus, the John Deere 8430 received a 4x4 MFWD 4WD all-wheel drive chassis with hydraulic brakes. We also note the hydrostatic steering mechanism, which has become a standard component for budget tractors. All-wheel drive can be combined with a center differential lock to increase cross-country ability. In addition, large all-terrain wheels with a deep tread pattern and self-cleaning effect contribute to improved off-road capabilities. High approach and departure angles, the absence of body overhangs, high ground clearance, powerful underbody protection and a durable frame structure also improved the tractor’s off-road capabilities. Based on this, the John Deere 8430R is able to overcome difficult obstacles without any assistance, including deep ruts and holes, muddy ground, as well as 30- and 40-percent climbs.
5. The tractor cabin is finished with the latest technology, starting with the basic configuration. Thus, the standard equipment includes an autonomous heating and air conditioning system, heated and electric driver's seat and external side mirrors, as well as the ability to adjust the steering column. A large number of workplace settings allows you to choose the optimal position depending on the height or build of the driver. In addition, the wide glass area played an important role - to improve visibility within the permissible working area. The body itself is made of high-strength alloy, and covered with multi-layer paint with a protective coating that protects the external panels from chips, scratches and other external influences, including flying stones and other hard objects. The cabin is perfectly sound and heat insulated, and protected from external noise and vibrations. Also in the cockpit is the main control panel, presented in the form of levers, buttons and switches, concentrated on one compact joystick. Operating mounted implements is quite easy and convenient, and does not require professional training. All indications about the operation of the moving parts of the tractor are displayed on the color display. In addition, data on fuel consumption, temperature and pressure in the working parts can be displayed on the screen. The display also displays information about the current mileage and the remaining time until the next maintenance. If any of the indicators deviate from the norm, the computer will try to fix the problem or inform the driver about it - using a sound signal or an icon on the display.
6. John Deere provides its customers with a high level of service. The manufacturer provides a factory warranty for original spare parts. We also note the developed John Deere dealer network with modern equipment. The company's service centers employ experienced specialists, as well as innovative diagnostic stands, which make it possible to determine the nature of the problem in a matter of minutes and eliminate it in a short time. Thanks to this, the tractor will be put into working condition as quickly as possible.

Reviews from owners and operators of “John Deere-8430”

According to farmers, one such energy-rich tractor can replace four conventional medium-sized tractors. This is achieved by high traction force, high productivity and speed, as well as reliability and quality of the entire structure.

"John Deere-8430" showed itself well in working with a 12-meter seeder. In conditions of round-the-clock work during sowing, he sows 120 hectares, and with the Rubin disk cultivator he cultivates 180 hectares. Over 20 hectares per shift. Moreover, it shows diesel fuel consumption of only 8 liters per hectare. In total, during the season the tractor cultivated 40 thousand hectares, having accumulated 3 thousand operating hours.

The disadvantages of the John Deere 8430 tractor include the sensitivity and susceptibility of the engine to the quality of diesel fuel. In winter, due to the use of low-quality diesel fuel, paraffin sometimes precipitates and clogs the filter, which leads to the engine stopping. To ensure normal operation of the equipment, it is necessary to install additional separators. In addition, such a tractor is very expensive. Spare parts and components for it are also not cheap, and many of them have to be “made to order” from other countries.

Reviews

• Anton, Novosibirsk. A good powerful tractor, suitable for tasks of any complexity. But my friends and I, work colleagues, use this machine mainly for snow removal, cleaning work and cleaning large areas. The tractor's lifting capacity is 8.5 tons, which allows operations related to loading or moving snowdrifts. The machine is equipped with a powerful hydraulic system, as well as attachments that allow you to work efficiently and smoothly, without overheating. An engine preheater is a very useful thing. The tractor is constantly subjected to heavy loads, and because of this it consumes a lot of fuel. In addition, the car is demanding on fuel quality.
• Oleg, Moscow. The John Deere 8430R tractor is in demand in our country in agriculture, and it confidently copes with municipal work - for example, we often use it for digging sewer and waste pipes, for snow removal procedures, and for clearing areas of debris. In addition, when connecting certain attachments, the machine is capable of pulling away heavy concrete objects, loading and unloading, transporting cargo, etc. But to a large extent, the equipment is adapted for hilling, cultivating, plowing and harrowing. Unfortunately, in the domestic market the machine is sold only on the secondary market, and the tractor does not have a developed service base, as in the USA or Europe, for example. And servicing a tractor yourself is not an easy task, because it has a lot of complex electronics, which often malfunction and display inaccurate information. It is impossible to completely disable all systems, and in this sense the John Deere 8430R is poorly suited for the Russian market. With timely maintenance, there are much fewer problems, but third-party service is very expensive.
