The Kirovets tractor of the K-9000 series is the basis for the mechanization of large land holdings

Equipment created to perform agricultural work must be reliable and durable. This is because you often have to work with different types of soil in different weather. The main task of the developers is to produce a machine that can work all year round. Domestic designers made themselves known to the whole world by presenting a series of equipment called “Kirovets”.

The K-9000 series machines became the beginning of the sixth generation of the legendary Kirovets family. They became a kind of breakthrough in the history of domestic tractor construction, while absorbing only the best qualities from their predecessors. As a result of long development, the Kirovets K-9000 was obtained. Its technical characteristics are superior to many similar models from famous brands and world leaders.

The main advantage of the K-9000 is its high performance and reliable design. The ability to work with a variety of attachments makes it a universal assistant for farmers and everyone involved in agricultural work.

The new “Kirovets” K-9000 is designed for plowing fields, using both driven and reversible plows, as well as for harrowing, cultivating and other work related to sowing crops. The tractor can be used year-round in almost all areas where labor mechanization is needed. It is worth noting that this model is not afraid of even the harshest climate, which puts it in a good light relative to its famous competitors. “Kirovets” K-9000 belongs to the 9th class (it all depends on the modification) and has all-wheel drive.

Purpose and features

The K-9000 series machines are distinguished by: functionality and performance, simple and reliable design solutions, the ability to be used together with most agricultural machinery and implements .

The list of operations performed by Kirovets includes:

• plowing the soil with various types of plows;
• harrowing the soil;
• work on stubble with cultivation devices;
• sowing work using complexes;
• mechanization of soil fertilization technologies.

The processing width, depending on the type of operation and trailed equipment, can reach 16 meters.

Thanks to the large wheels, the unit exerts little pressure on the ground, which makes it possible to control it on excessively moist soils.

The tractor is used for transporting goods, in land management, land reclamation work, etc.

The machine is intended for all-season use with an operating time of 2.5-3 thousand engine hours per year when operating on 5,000 hectares of land without loss of technical parameters.

How to use Kirovets K-9000 in agriculture

New tractors have only recently begun to be produced by the enterprise, and therefore it is still almost impossible to find those who could share their experience of working on the new Kirovtsy. Another factor in the low popularity of the machine is its very high price, and therefore even owners of large farms cannot always afford to buy them.

But, nevertheless, the characteristics of the K-9000 make it a desirable purchase for every farmer. “Kirovets” is a powerful tractor with high cross-country ability, which allows it to be used for work on soils with high humidity. The quality of the tractor is also evidenced by the fact that almost all of its components, assemblies and systems are manufactured by the world's best brands, which significantly increases its reliability, extends its service life and improves its technical characteristics. When manufacturing the tractor, the designers paid special attention to the comfortable work of the operator.

However, if you really look at some of the advantages of the car, they turn into significant disadvantages.

However, without going into details, the use of Kirovets can significantly speed up and simplify most agricultural work. One K-9000 can replace several tractors from other manufacturers at once.

The K-9000 is characterized by high maneuverability, which significantly expands the possibilities of its use. The tractor is designed for plowing with driven and reversible plows, deep loosening, cultivating and peeling, harrowing, sowing using mechanical and pneumatic seeders, tilling the soil and applying fertilizers.

In addition, the K-9000 can be effectively used for transportation, leveling, earth-moving work, as well as land reclamation, compaction and snow retention. This machine can be used all year round, as it is not afraid of the harshest conditions.

Modifications and their technical characteristics

The K-9000 series includes five modifications of machines: K-9360, K-9400, K-9430, K-9450, K-9520.

The main differences are in the power of the diesel power plant - it corresponds to the last three digits in the model designation. The overall dimensions of the last two devices differ slightly in width.

Engine

Those who are planning to purchase the Kirovets K-9000 will be interested in the question: what engine is installed? Some models are equipped with a diesel six-cylinder engine OM 457 LA with a displacement of 11.9 liters and manufactured by the German brand Mercedes-Benz

.
There are also models equipped with an eight-cylinder V-shaped OM 502LA with a volume of 15.9 liters and a power of 516 hp. Each K-9000 engine is additionally equipped with turbocharging.
Before being supplied to the turbine, the air is forcibly cooled, which makes it possible to pump a larger volume of air into the cylinders. Fuel injection adjustment is carried out via electronic systems. Each cylinder has its own injector pumps, adapted for the use of domestic fuel. It should be noted that the engine pre-heating system is provided as standard and guarantees high-quality starting at sub-zero temperatures. The weight of a full fuel bunker is 1.03 tons. Each fuel tank is equipped with elements for additional cleaning and automatic heating of fuel if its temperature drops below -10 degrees. Each model of the K-9000 tractor has a different engine power, which can range from 354 to 516 hp. K-9000 fuel consumption is 150 (205) g/hp per hour (g/kW per hour).

Transmission

All modifications of tractors equipped with power plants no more than 430 hp are equipped with an automatic transmission of the Powershift system

, the design of which is based on the dual connection of two mechanical boxes.

In addition, the gearbox has a dual clutch with two independently operating discs, which made it possible to use it as a regular automatic transmission without sacrificing torque. The gearbox operates in four ranges, each of which has four forward and two reverse speeds, for a total of sixteen forward and eight reverse.

Tractors with an engine from 450 to 520 hp are equipped with
a TwinDisc gearbox
, which provides gear shifting in one range, while completely eliminating any interruption in the power flow. The number of gears in the range is 2 reverse and 12 forward.

The tractor reaches speeds from 3.5 to 36 km/h.

Chassis

Both axles of the tractor are driven, thanks to which its unique cross-country ability is achieved, which is also facilitated by the use of “no-spin” technology. Each axle gearbox is equipped with differential cross-wheel self-locking mechanisms. Gear transmissions in the axle gearbox and final drives are placed in such a way that they provide maximum agricultural clearance. Gearboxes and axle gears are manufactured using high-tech equipment with maximum precision. The main parts of the box are made of high-strength steel. The brake system has a pneumatic drum-type drive.

Steering

“Kirovets” is famous for its high-quality articulated solar frame.
For the manufacture of turning mechanisms, hinges are used that work effectively in the horizontal and vertical planes, which ensures the smoothest movement of the vehicle, increasing its maneuverability and cross-country ability. In the horizontal plane, the angle of rotation of the frame is 16 degrees in each direction, while the turning radius on the outer wheels is 7.4 m. To improve the characteristics of the hinge mechanism, a plain bearing is installed.
The movement of the hinge in the horizontal plane is ensured by a replaceable pair of bushings sliding in the tubular element. At the same time, to reduce the negative impact of the environment, the hinge mechanism is protected with special cuffs. To improve the quality of steering, an electro-hydraulic power steering with Zaur-Danfoss dispensers is used. To ensure more accurate movement, the unit can be equipped with GPS navigation.

Hydraulics system and attachments

“Kirovets” K-9000 has impeccable technical characteristics, which allows it to be used with most types of attachments.

The hydraulic system consists of a Sauer-Danfos pump, a Bosh-Rexroth hydraulic distributor, which has an additional filter element and a radiator designed to cool the working fluid and a 200-liter supply tank.

The LS system regulates the intensity of the flow of working fluid and the speed of its supply.
The main advantage of the system is the reduction of consumption and prevention of loss of hydraulic fluid. The system independently reduces pressure and reduces flow, adjusting its parameters to the desired load. The main disadvantage of the system is its complexity, due to which it requires more precise adjustment.

Tractor cabin

The tractor cabin is equipped with a reliable frame that ensures absolute operator safety.

It is distinguished by an increased level of comfort, since the tractor driver is reliably protected from all external noise, which is achieved by its high degree of sound insulation. Special cushions on which the cab is installed protect the tractor driver from the effects of vibration. In addition, it is absolutely sealed, which prevents the penetration of foreign odors and dust into it. The tractor is characterized by maximum ease of control, and all its operating parameters are constantly monitored by the on-board computer.

Historical reference

Kirov Tractor Plant is one of the oldest Russian enterprises. It was here that the first model of Soviet tractors, the Fordson-Putilovets, was developed. Serial production of these machines began in 1924 and continued until the start of the Great Patriotic War. The Kirovets series was first published in 1962. At this time, the development of agriculture in the USSR had reached a dead end and there was an urgent need for heavy and productive tractors. The appearance of “Kirovtsy” on the fields of the country made it possible to make a sharp leap in the agricultural industry. To this day, over 475,000 cars have been produced under the Kirovets brand. Of these, about 50,000 successfully work in the fields of our country. About 12,000 vehicles were exported. By the way, in 2012 the company celebrated its 50th anniversary. Today, 11 modifications of heavy tractors are assembled in the plant’s workshops, including the K-9000. The management of the Kirov plant claims that it is constantly modernizing its model range, and is not going to stop there.
