"John Deere-8430" is a heavy universal row-cultivator designed to perform energy-intensive technological operations. Due to its high power and productivity, this model is intended only for large farms. Those who have significant areas under crops and are interested in using powerful equipment that is easily aggregated with advanced high-performance trailer complexes. Such a tractor is a powerful energy production tool. In order to load it and achieve maximum profitability, you need to have not only extensive fields, but also modern trailer and attachments. All the details about the "John Deere-8430" and the specific experience of its use - below.

On average, one tractor "John Deere-8430" is designed for complex processing of 1.5-2 thousand hectares of land per season, and such a load pays off in 2-3 years. Under the condition of normal operation and timely maintenance, it is able to work 15 thousand hours before the first major overhaul. Along with the tilled modification 8430, a tracked version was also produced - 8430T.

The company is named after its founder (in 1837, an American blacksmith and inventor opened his business in Moline, and in the future - an industrialist - John Deere). During 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 bought the Waterloo tractor factory. Soon it was tractors for agriculture that for a long time, one might say, "forever", became the main specialization of the corporation. The traditional green and yellow colors of the "Dir" technology have long been well known throughout the world.

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

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 This series included four models: 8230 - 250 hp; 8330 - 280 hp; 8340 - 305 HP and 8530 - 330 hp Currently, they have been replaced by a new generation of powerful "Dir" tractors - the 8R series.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

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

The tractor is prepared for the special navigation system "Auto-Trac", which guarantees the most accurate (+/- 3-10 cm) run boundaries and makes it possible to work smoothly, including at night, with terrain mapping. This will require additional installation of GreenStar equipment.

Namely, there are several options for signal accuracy:

SF1 system- this 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– pass-to-pass accuracy ±10 cm (15 minutes pass-to-pass);
StarFire RTK System– real-time kinematics with an accuracy of less than 2 cm (within 10 km from the base station and 68% of the time).

These technologies help increase productivity, reduce the area of mutual overlap of adjacent passages, reducing diesel fuel and other components of the production cost. In addition, GreenStar driving systems allow the operator to pay more attention to the attachments and monitor the quality of their functioning.

"John Deere-8430" is capable of performing any agrotechnical operations with wide-cut agricultural implements for cultivating the land. The machine provides the main means of mechanization of work in the conditions of intensive and classical technologies for growing a full range of agricultural crops. The tractor flexibly fits into the specific parameters of any field, is equipped with a complete set of necessary settings for all types of work.

In combination with agricultural implements appropriate for their intended purpose, a tractor with maximum efficiency:

cultivates the soil (plows, harrows, cultivates, etc.) on large fields of large peasant farms and agricultural holdings;
tows multi-row planting units, equipment for harvesting green forage and harvesting;
loosens, weeds, fertilizes, performing such work without damaging the rows of plantings, which allows the parameters of the chassis of the machine, its agrotechnical clearance;
fills and forms pits for silage;
transports significant volumes of cargo for a wide variety of purposes in conventional and dump trailers.

The John Deere Power Tech Plus engine is equipped with a Common Rail direct fuel injection system manufactured by Denso. Also, this power unit is equipped with an automatic fuel pumping system "Auto-Prime".

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

Power Tech Plus engine parameters 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).

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

The high pressure fuel rail (HP-CR) fuel system promotes instantaneous load response for additional fuel economy.
The air-cooled intercooler improves engine performance and efficiency.
An electronic fuel pump that automatically bleeds air after changing fuel filters reduces downtime.
A viscous-coupled cooling fan and an improved Vari-Cool fan drive also contribute to fuel economy.
The dry air filter has an inlet on the cab support.
Separate injection pumps.
Fuel tank cooler.

The first option, a 16-speed transmission, was developed by John Deere specialists based on the Power Shift system that appeared in 1994. Thanks to the built-in electronics and closed-loop gearshifting, gear shifting occurs in a smooth rhythm.

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

There is a special "Power Zero" function designed to hold the tractor in place in the event of braking on a slope. This version of the gearbox has a positive effect on the patency of the car, due to its instant response to changing loads. Operates in four modes - manual, PTO, high traction control and low traction control, economical transport mode. However, this transmission is very expensive and has a complex design.

Tractors "John Deere-8430" implemented an independent lever-articulated suspension "ILS", automatically adjustable. The “ILS” independent front axle suspension maximizes power transfer to the ground, for consistently high performance, even when operating in very uneven terrain. Suspension system is hydro-pneumatic, constant action, with automatic leveling, automatic load compensation and active traction geometry for three-point hitch implements.

The front steering axle is also the leading one. 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 roadway;
braking optimization - activated when both brake pedals are pressed.

The tires used are 800/70 R38 and 600/70 R30.

The brakes on this tractor are multi-disc. They work separately for the rear wheels, and are mounted on a shaft axle between the differential and the final drive of the bead. They are controlled by hydraulics, duplication goes through a mechanical drive.

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

Three-point rear hitch - electro-hydraulic, with full electronic lower link traction control, hitch damping, external fender switches.

Lifting capacity - 7847 kg; or 8300 kg (additional option). The maximum lifting capacity on hooks is 10788 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-plate 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.

About Deer & Company Corporation

Deere & Company is a multinational engineering corporation headquartered in Moline, in the US state of Illinois. It produces agricultural, industrial, logging tractors, trailers and attachments for them; harvesters; construction, gardening, snow removal equipment. As for agricultural machinery, it is the largest manufacturer in the world. The company is named after its founder (in 1837, an American blacksmith and inventor opened his business in Moline, and in the future - an industrialist - John Deere). During 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 bought the Waterloo tractor factory. Soon it was tractors for agriculture that for a long time, one might say, "forever", became the main specialization of the corporation. The traditional green and yellow colors of the "Dir" technology have long been well known throughout the world.

The company has old ties with our country. The first delivery of John Deere 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 annually several thousand tractors of this brand. In our time, assembly plants for John Deere tractors and combines were opened in the Moscow and Orenburg regions, and Samuel Allen, chairman of the board of directors and executive director of the company, personally met with Vladimir Putin in 2010. Not only assembly plants, but also plants of the full production cycle, owned by Deer and Company, operate all over the world: in the USA and Canada, European countries, India and, of course, China. "North American Distribution Center" "Deere & Company", which is located in Rock Island, Illinois, this giant product warehouse, spread over an area of 246 thousand square meters and is on the 4th place in the list of the largest buildings and structures on the planet (by their area directly on the ground).

The place of the tractor in the model range of the plant. Model Features

The undoubted advantages of this model include its saturation with advanced technologies, high power combined with fuel economy and work efficiency, and versatility. Among the innovative technologies used in John Deere-8430 are: fuel injection control by an electronic system; satellite positioning system in the Precision Agriculture automatic control system; telematic system for remote monitoring of the operation of the tractor and its systems. The tractor is prepared for the special navigation system "Auto-Trac", which guarantees the most accurate (+/- 3-10 cm) run boundaries and makes it possible to work smoothly, including at night, with terrain mapping. This will require additional installation of GreenStar equipment.

Namely, there are several options for signal accuracy: SF1 system- this 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– pass-to-pass accuracy ±10 cm (15 minutes pass-to-pass); StarFire RTK System– real-time kinematics with an accuracy of less than 2 cm (within 10 km from the base station and 68% of the time). These technologies help increase productivity, reduce the area of mutual overlap of adjacent passages, reducing diesel fuel and other components of the production cost. In addition, GreenStar driving systems allow the operator to pay more attention to the attachments and monitor the quality of their functioning.

Scope of tractor «John Deere-8430»

In combination with agricultural implements appropriate for their intended purpose, a tractor with maximum efficiency: cultivates the soil (plows, harrows, cultivates, etc.) on large fields of large peasant farms and agricultural holdings; tows multi-row planting units, equipment for harvesting green forage and harvesting; loosens, weeds, fertilizes, performing such work without damaging the rows of plantings, which allows the parameters of the chassis of the machine, its agrotechnical clearance; fills and forms pits for silage; transports significant volumes of cargo for a wide variety of purposes in conventional and dump trailers.

Tractor engine "John Deere-8430"

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 provide 4 valves on each cylinder. The John Deere Power Tech Plus engine is equipped with a Common Rail direct fuel injection system manufactured by Denso. Also, this power unit is equipped with an automatic fuel pumping system "Auto-Prime".

Features of the Power Tech Plus engine: 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 fuel rail (HP-CR) fuel system promotes instantaneous load response for additional fuel economy. The air-cooled intercooler improves engine performance and efficiency. An electronic fuel pump that automatically bleeds air after changing fuel filters reduces downtime. A viscous-coupled cooling fan and an improved Vari-Cool fan drive also contribute to fuel economy. The dry air filter has an inlet on the cab support. Separate injection pumps. Fuel tank cooler.

Tractor transmission "John Deere-8430"

The design of the tractor "John Deere-8430" provides for two types of gearboxes: "Automatic Power Shift" - automatic speed manual transmission; "Auto Power" - automatic continuously variable hydrostatic-mechanical gearbox. 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 John Deere specialists based on the Power Shift system that appeared in 1994. Thanks to the built-in electronics and closed-loop gearshifting, gear shifting occurs in a smooth rhythm. This gearbox has sufficient strength to operate under sudden and high-torque loads, while maintaining the speed of response to the control action and the reliability of gear changes. When the engine power is reduced or the load on the tractor changes, gear shifting occurs automatically, within the selected range. In total - 16 forward and 5 reverse gears.

The stepless gearbox "Auto Power", 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 machine 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 the event of braking on a slope. This version of the gearbox has a positive effect on the patency of the car, due to its instant response to changing loads. Operates in four modes - manual, PTO, high traction control and low traction control, economical transport mode. However, this transmission is very expensive and has a complex design.

Suspension, chassis, axles, brakes

The rear axle on the 8030 series can have an axle with a length of 2438 mm. An axle of 2438 mm is provided for mounting single rear wheels on the rear axle of the tractor, and an axle with a length of 3002 mm is provided for mounting dual wheels. The front steering axle is also the leading one. Torque is applied to the front-wheel drive at all gearbox speeds in the following three modes: forced connection; automatic - when changing the parameters of the roadway; braking optimization - activated when both brake pedals are pressed. The tires used are 800/70 R38 and 600/70 R30. The brakes on this tractor are multi-disc. They work separately for the rear wheels, and are mounted on a shaft axle between the differential and the final drive of the bead. They are controlled by hydraulics, duplication goes through a mechanical drive.
