John Deere tractors (John Deere) - models and characteristics, video

Purpose of the machine

John Deere 8430 is a universal-purpose wheeled tractor used in agricultural operations with wide-cut agricultural implements for cultivating land. The machine is the main means of mechanizing work when using intensive and classical technologies for growing crops. The unit flexibly fits into the specific parameters of each field and has the necessary set of settings for all types of work.

In combination with agricultural implements of different purposes, the tractor with sufficient efficiency:

cultivates the soil (plows, harrows, cultivates, etc.) on large fields of large agricultural holdings;
tows multi-row planting units, green mass harvesting and harvesting machines;
the parameters of the machine's chassis and agrotechnical clearance make it possible to loosen, weed, apply fertilizers, and carry out similar work without damaging the rows of plantings;
forms and fills silo pits;
transports large volumes of cargo for various purposes in conventional and dump trailers.

"Active Command Steering - 2"

Active Command Steering - 2 or (ACS-2) will replace the original Active Command Steering system and will be available as a factory option on 7R and 8R tractors. The new feature reduces steering effort for the operator and improves line retention during transport. With ACS, two operators can simultaneously adjust the steering and steering wheel resistance. Alternatively, they can incorporate variable or ratio steering.

ActiveCommand Steering 2 gives operators enhanced control of the steering system to get the job done better. For example, ACS-2 can be configured to make it easier to turn the tractor in the field, or to make it easier to control the tractor during transport. With the ACS-2 equipment, it is noticeably easier to negotiate turns compared to a tractor without this option,” says Jardon.

John Deere 8430 in use

Features of units, components and mechanisms

1. Power plant for 4 working strokes, diesel unit PE 6068B with an in-line longitudinal block for 6 cylinders, equipped with a turbine air charging system. Cooled by liquid flow in a closed system. Direct fuel injection and removal of combustion products are provided by 4 valves on each cylinder.

2. Transmission. In the basic version of the tractor, a 16-speed automatic manual transmission was installed on the machine. A reliable device with easy and smooth manual gear shifting, providing speeds from 2 to 43 km/h. The box is equipped with an automatic mode selection function when the load on the tractor changes. As an option, the tractor was equipped with a hydrostatic-type gearbox operating in an automatic stepless switching mode - AutoPower.

3. The rear axle of the unit is driven, assembled in one housing with transmission units. The differential is controlled by an electro-hydraulic device.

4. Drive-type front steered axle. Torque is supplied to the front-wheel drive in all transmission gears in three modes:

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

5. Power take-off through the shaft at the rear of the tractor. Revolutions 540 and 1000 per minute.

6. Selecting the direction of the steering wheel. Hydrostatic amplifier with control of operation by a load sensor and regulation of flow parameters. The actuator is a power hydraulic cylinder. The steering column is infinitely adjustable in tilt and length.

7. Multi-disc brakes. They work separately on the rear wheels, installed on the shaft axis between the differential and the final drive of the side. Controlled by hydraulics, redundant through a mechanical drive.

8. The unit for canopy of agricultural equipment is mounted in the rear part of the frame. It has a four-link articulated device with gripping hooks. The hydraulic circuit of the canopy ensures the required position of the hinged mechanism, the operation of which is ensured by 4 pairs of hydraulic outlets.

9. The lift type of the towing coupling unit ensures aggregation with trailed implements.

10. The cabin is heat and sound insulated. Vibration protection, ventilation, air conditioning and heating units provide comfortable working conditions. Single-piece windshield and rear glass, 360° illumination of the working area allow you to visually monitor the operation of the tools used.

Position on the agricultural machinery market

John Deere 8430 discontinued in 2009. The price of tractors with operating hours starts from 3.7 million rubles. Analogues:

units from JSC "Petersburg Tractor Plant" K-744R;
New Holland T 8040
Case Magnum MX 300

Series 8 tractors from Deere & Company are effective when cultivating large-area lands of large agro-industrial complexes - the unit is designed to service an area of 2 thousand hectares. In conditions of farms with stable yields, its payback is 3 years. Before a major overhaul, the machine operates for 15 thousand hours.

American John Deere tractors

Among the agricultural machinery presented on the domestic market, John Deere products are in particular demand. The tractor models produced by the American brand are distinguished by their versatility and functionality. This significantly expands the scope of application of agricultural machinery from tillage to operation on livestock farms. Other advantages of John Deere technology include the following:

the model range includes both all-wheel drive wheeled and high-performance tracked units;
Each tractor produced by Zhandir is distinguished by high build quality and ease of operation;
all equipment is designed for operation in difficult conditions with the use of large traction forces (both in agricultural work and when transporting goods);
the possibility of using various attachments (due to indicative hydraulic characteristics);
tractors are equipped with powerful but economical engines;
high load capacity of each model;
the presence of intelligent control, as well as the automatic driving system, increase the accuracy of all operations;
remote telemetry allows you to optimize the process of equipment diagnostics and increase its operational life;
thoughtfulness and ergonomics of the cabin.

For the convenience of the tractor driver and quick completion of assigned tasks, the Jondir tractor is equipped with a comfortable adjustable seat. In addition to tractors, the American manufacturer supplies the domestic market with several models of crawler bulldozers powered by turbine diesel engines.
