Tractor k 744
The Kirovets models from the K-744 line, which began production in 1995 and underwent extensive modernization in the early 2000s, were the result of a radical change in the outdated K-700 and K-701 tractor models. They have incorporated all the latest improvements in technology and equipment, interior and exterior elements, maintaining undeniable leadership among Russian equipment of this type in the power range of over 300 hp.
Purpose
The K-744 belongs to the high 5th traction class and at the same time has extensive capabilities for working with various trailed tools and all kinds of attachments. This “comprehensiveness” of the machine expands the boundaries of its application to the status of a multifunctional draft unit and allows it to solve a wide range of problems:
- The main purpose is agricultural work of all types.
- Transporting heavy loads over short and long distances.
- Work at fishing and rock mining sites.
- Issues of construction, road and utility services.
The value of the model lies in the fact that in climates of different latitudes it can be freely used year-round, and for the most difficult tasks of transportation, towing, etc.
INTERESTING! Only one K-744 tractor can completely cultivate (prepare and sow) areas of up to 5 thousand hectares per season, ensuring the minimum cost of each hectare of crops.
Advantages and disadvantages
At the moment, domestic tractors of the Kirovets K-744 brand are one of the most popular and most powerful tractor equipment purchased in Russia, which is explained by the unique combination of many useful properties in one unit:
- Equipped with powerful and at the same time economical turbodiesels produced by well-known companies with 6 or 8 cylinders, developing power up to 428 hp. and torque up to 2000 N*m (TMZ, YaMZ, Cummins, Mercedes-Benz).
- Continuous operation without refilling for up to 14 hours thanks to the large gas tank.
- The ability to change gears without interrupting the power flow under load.
- Increasing, if necessary, traction capabilities by installing an additional set of dual wheels and ballast weights.
- High driving characteristics due to all-wheel drive and the presence of elements that increase driving efficiency:
- self-locking differential;
- planetary type wheel reducer;
- sprung front axle.
- Increased maneuverability, which is ensured by a very small turning radius for such colossal equipment due to the action of the articulated frame of the machine.
- Convenience, comfort and safety of the operator in an ergonomic cabin with modern equipment.
- Can be combined with any trailed and mounted equipment.
- Relatively affordable in comparison with similar foreign equipment.
ATTENTION! Some disadvantage of the K-744 series tractors is the problem of the standard hydraulic system, equipped with an NSh pump, which produces significant energy losses. To eliminate this problem, machines are equipped with oil flow regulators - electronic with remote control or manual.

Obviously, the user chooses between reliability and low cost of repair in the event of a breakdown.
The power of the hydraulic system has been increased by increasing the pump output to 180 l/min. The hydraulic distribution mechanism of a five-section design with separately controlled elements made it possible to integrate with all modern machines and implements.
The proprietary transmission with non-stop gear shifting is time-tested and has proven its reliability in any situation. The rear linkage system is a three-point, high-power one. Its performance has been proven through testing and real-world operation.
The large-capacity fuel tank was specially designed for seasonal use of the tractor without the need for refueling. To increase the productivity of the K-744R1 tractor during agricultural work, the manufacturer has provided a wheel doubling system. This increases traction and flotation while reducing ground pressure.

Description and purpose
Kirovets K-744 is a high-performance machine, on the assembly line since 1995. Since 2002, the Kirov Plant began to produce only this model, but in several versions. In this regard, the previous machines K-700, K-701 and K-703 were removed from the assembly line for obvious reasons. At the moment, the K-744 has four modifications. The tractor received its last major update in 2014. The modernized vehicle is distinguished by higher traction characteristics, a modern cabin manufactured in accordance with comfort and safety requirements, as well as multifunctional hydrostatic steering equipment. The Kirovets K-744 model is widely used mainly in agriculture. This tractor is aimed at a mass audience. It is often purchased by large logging companies, as well as utilities, builders and private entrepreneurs. In farming, this device is in demand in operations such as plowing soil in various ways, towing trailers, loading and unloading. In the construction and public utilities sector, the equipment is used as a loader and in repair and installation work. In road construction, the tractor mainly transports heavy loads, including concrete structures, since the machine has a high load capacity. The machine is perfectly adapted to harsh weather conditions. Thus, in agriculture, this is one of the few machines that is capable of completely cultivating an area of up to 5 thousand hectares in a short time.
