Agricultural tractor K-744: technical capabilities of the model

Many farmers during the purchase of expensive machines are wondering: is it worth choosing domestic machinery or is it better to give preference to imported machines? Consider a domestic unit, which is characterized by good functionality and price. Find out what is the K-744, for what it is intended.

A bit of creation history

The history of the tractor begins in 1924, when the Red Putilovets plant (now the Kirovsky Zavod plant) began to produce American tractors under the name Fordson-Putilovets. In fact, this moment marked the beginning of the Soviet tractor construction industry.

In the second half of the 30s, we started production of the Universal-1 and Universal-2 tractors. The first "Kirovs" appeared only in 1962, when the factory started production of the first generation of agricultural tractors. Models K-700 and K-700A were presented. The second option had more horsepower. Moreover, the first batch of 50 tractors left the plant only in 1963. In 1975, the second generation of agricultural tractors appeared. Model K-701 was presented, which already had 300 "horses". In the late 70s, the plant produced the first generation of “Kirov workers” intended for industrial work (K-703).

The most popular and affordable means for today are cultivators and tillers. Through the use of attachments using the motoblock, you can dig and pile up potatoes, remove snow, dig the ground, and use as a mower.

In the mid-80s, the third generation of agricultural tractors called K-701M. They differ in power (335-350 hp.).

In exactly 10 years, the 4th generation of tractors appears. The K-734 and K-744 models, which differed in quite average power (250 and 350 hp), were designed for export. It is 1995 that can be considered the year of birth of 744 models. Further, after 5 years, the K-744R version was released, which belonged to the 5th generation of tractors.

Purpose and scope of work

This model is a general-purpose machine that is used for primary and preplant tillage. It effectively interacts with wide-range sowing complexes, it can work with various attachments.

The machine is designed for agricultural work of all kinds, and for the transportation of various goods over short and long distances. It can be used in industry or logging, utilities. The tractor will be involved in the repair and laying of pavement, repair of water supply and sewage. It can be concluded that we are a multifunctional machine, which you can assign a huge number of tasks. This possibility expands the functionality of the tractor.

Did you know? The smallest tractor in the world is in the museum of Yerevan. Its length is 1 cm, while it can move under its own power.

Operating power is slightly less and equal to 279 liters. with.

The rotational speed of the crankshaft is 1900 rpm.

Cab and steering

The cab has an excellent all-round visibility, which is achieved by the driver's seat's central position (there is also a second seat, which is located on the left). There is isolation from noise and vibration, as well as built-in air conditioning. K-744 tractor cab Controls:

  • Transmission;
  • brake, clutch and accelerator pedals (accelerator);
  • the steering column, which provides on / off wipers, as well as light adjustment (high / low).

Dashboard:

  • lamps and indicators;
  • emergency gang and clearance lights;
  • on / off fan, air conditioner and heating;
  • speedometer;
  • tachometer;
  • oil pressure and temperature;
  • ammeter;
  • voltmeter;
  • air pressure sensor in the system;
  • hour counter

Familiarize yourself with the tractors: DT-20 and DT-54, MT3-892, MT3-1221, Kirovets K-9000, T-170, MT3-80, MT3 320, MT3 82 and T-30, which can also be used for different types of work.

Transmission and chassis

Chassis consists of the following elements:

  • clutch;
  • rear and front axles;
  • gearboxes;
  • driveshafts with supports.

Permanent drive goes to the front axle. If necessary, connects back, after which the car becomes an all-wheel drive.

Torque is transmitted by means of cardan shafts. The supply of power to the front axle is carried out through a single node. To provide a rear axle drive, an intermediate support is installed in the tractor at the point of articulation of the tractor. A hydraulic drive is used to control the direction of travel. The frame is divided into two parts.

To ensure optimum performance, axles and differentials were installed in the axles, through which the force is transmitted to the wheels by means of semi-axes. In this way, different wheel speeds are achieved when turning.

Brake system

Braking and control of the brake system is provided by the pneumatic system. It is used for separate control of bridges, as well as attachments.

Fuel tank capacity and flow rate

The fuel tank has a volume of 640 liters. Fuel consumption during operation at rated power is 174 g / l * h. At the operating power consumption is 162 g / l * h. It is worth understanding that the specified expense is maximum. That is, at rated power, the tractor will not consume more than 174 g / l per hour.

The maximum speed is 28 km / h and the minimum is 4.5 km / h.

Attachment Equipment

To put the attachment on the machine, you need to have a factory attachment that will provide the operation and control of additional parts.

The K-744 has a good high-performance hydraulic system with an axial piston pump that pumps about 180 liters per minute. Also, the hydraulic distributor includes 5 sections, and 4 hydrolines are allocated for the needs of agricultural units. As standard, the machine has a three-point attachment type, which allows you to put the following guns:

  • mechanical and pneumatic seed drills;
  • all kinds of cultivators, including complexes that allow sowing;
  • various plows;
  • deep-rippers;
  • towing devices of any type.

Important! Since 2014, tractor attachments are fully consistent with international standards. This allows you to install it on modern agricultural machinery.

Separately, it should be said that the special properties of the hinge allow you to use the machine as a roller for laying asphalt, welding machine, as well as a loader.

Advantages and disadvantages

Pros:

  • a sufficiently large margin of safety, which allows you to work up to 2 thousand hours without the mandatory inspection of equipment;
  • equipment of the cabin, as well as the conveniences described above, allow the Kirovtsi to compete with imported cars;
  • capacious tank and low fuel consumption;
  • in the event of a breakdown, the purchase of the necessary part is quite simple and relatively cheap;
  • Excellent functionality that many import copies cannot compete with.
Minuses:

  • without twinning the wheels, the weight of the tractor leads to damage to the upper fertile layer, which is why, as standard, the machine is not the best option for agricultural work;
  • after installation of attachments, there is a loss of power, which is due to the presence of flaws in the hydraulic system;
  • In some instances, plastic pneumatic tubes are installed in the braking system, which break down after a year of active use.

We recommend that you read how to choose a mini-tractor for work on the backyard plot, about the features of mini-tractors: "Bulat-120", "Uralets-220" and "Belarus-132n", and also learn how to make a mini-tractor with your own hands from a motoblock and a mini tractor with a breaking frame.

It is worth noting that the advantages of the car more than the minuses. The developers have worked well on the improvement of the machine, therefore, in terms of functionality and comfort, it can be compared with the expensive imported machines that we have on the market. You should always remember about the price of the goods, as the domestic machine will be cheaper than foreign ones.

Modifications

At the moment, there are three main modifications, namely:

  1. K-744P1. It features less fuel consumption, as well as an additional safety cage for the cab. There is also a sprung front axle.
  2. K-744R2. Installed a powerful engine 350 hp, which allows you to productively use heavy attachments. Other changes affected the cabin, which has become more convenient. Also, this model can "boast" light hydraulic volume control.
  3. K-744P3. The most powerful variation, which has a 400-horsepower engine. The manufacturer replaced the domestic air purifiers with imported ones that have a high dust holding capacity. Installed hydraulic pump, which allows you to adjust the liquid flow. It is possible to install additional ballast.

Did you know? In the 50s of the last century, the well-known company Porsche was engaged in the production of tractors. Interestingly, the founder of the company during the Second World War was engaged in the development of German tanks "Tiger" and "Mouse".

Now you know what the K-744 is, why this machine is more than competitive, and what its disadvantages are. Please note that the modifications have imported components, because of which in the event of a breakdown, there may be difficulties both with the price and with the possibility of purchasing spare parts. There are also important differences between the standard and premium version, which consist in less fuel consumption.

Feedback from network users

Hello. Those who are engaged in agriculture, I want to advise the excellent Kirov K744. He has several modifications depending on the brand of the engine and its power. Engine power goes from three hundred horses to four-twenty-eight. Gather this tractor in the Altai Territory. Sales is a trading company ACM. By design, I can say that a very interesting design was made for both the cab itself and the whole tractor. The volume of a tank is 600 liters. The gearbox costs 16/8 four mode with hydraulic gear shifting without interrupting the flow of power within each mode and mechanical mode switching. And the price is acceptable than that of imported tractors. Kirovets can be used with all suitable agrotechnical units. In agriculture, a must.
