Russia is once again positioning itself as a power that is actively developing all sectors of agriculture. Accordingly, the demand for agricultural machinery begins to increase. A promising area of ​​the market is the cultivation of grain crops. In this area of ​​agriculture it is impossible to do without grain harvesters. After the collapse of the Soviet Union, harvesters were practically not produced in our country, so farmers were forced to purchase the necessary machines from Western manufacturers. Currently, grain harvester production lines are operating at full capacity, offering consumers thousands of units of equipment annually. A prominent representative of the family of grain combines is the Torum 740, which is produced by Rostov. This unit is positioned as power class 7 equipment, and quite confidently competes with Western-made classmates. According to experts, Torum 740 is an innovative technology with great capabilities. The machine has been produced since 2011, and during its existence it has convinced farmers of its reliability and functionality. Therefore, it makes sense to present this combine for a more detailed review.

Description

Designed for harvesting a wide range of crops in fields with high yields and complex agricultural conditions.
Torum is a high-performance rotary grain harvester with high efficiency, unpretentiousness, ease of maintenance, and reliability. This powerful machine is capable of harvesting over 2000 hectares of various crops in one season, threshing from 40 tons of grain per hour, i.e. over 300 tons per eight-hour shift.

The Torum combine is designed for harvesting traditional grain and cereal crops using direct and separate combining. The range of harvested crops ranges from wheat to rice. A high-performance combine with a rotary threshing scheme is well suited for farms with large acreage and high yields.

In addition to high productivity and efficiency, Torum combines are distinguished by their ability to work effectively on clogged and wet backgrounds. This is due to the use of a unique Advanced Rotor System (ARS) threshing system in the design of the technological path, which includes three innovative solutions: a beater feeder, a rotor with a rotating deck and three threshing points, and a stepless rotor drive.

1. The tilting beater chamber provides higher throughput and lower power consumption thanks to Feed & Boots technology;
2. A three-thread rotor allows threshing at three points, and a rotating self-cleaning deck allows you to work on wet backgrounds;
3. The continuously variable rotor drive guarantees fast and precise adjustment of the thresher.

Feeder: Feed & Boost.

Feeder beaters level and accelerate the compressed mass before entering the rotor. The implementation of the “Feed & Boost” principle ensures the stability of the technological process and reduces the energy consumption of the unit. The advantages of the camera are especially pronounced when working on uneven windrows or when there is high humidity and contamination of the crop.

Practice has shown that, compared to traditional slatted conveyors, such a scheme increases the throughput of the feeder chamber by 20%, while energy consumption is reduced by 15%.

For convenience and to reduce the time for connecting adapters, all Torum combine harvesters are equipped with a single hydraulic connector, the quick-release connection of which is designed in such a way that prevents contaminants from entering the hydraulic system.

Stepless rotor speed control. The rotor is driven through a planetary variator and controlled by a hydraulic motor, which ensures precise and smooth adjustment of the rotor speed over the entire operating range.

Threshing device - ARS.

The Advanced Rotor System is a unique threshing system that has no analogues, which provides a significant increase in the productivity of the rotary combine, especially when harvesting in difficult conditions.

The problem common to all rotary combines - clogging the thresher with wet mass - is not an obstacle for Torum, thanks to the ARS threshing system: a beater feeder chamber that levels and accelerates the mass before feeding it to the rotor, a rotating rotor deck that eliminates the presence of a “dead zone”, and a stepless drive rotor, thanks to which the operator can set any rotation speed ranging from 250 to 1000 rpm and achieve optimal threshing.

A rotating deck has two undeniable advantages over a traditional stationary one. Firstly, it provides a large threshing area, which allows you to use the full potential of the rotary threshing device and increase its productivity. Secondly, it makes it possible to work on wet or clogged bread and rice by preventing the formation of stagnant (dead) zones, freezing of the mass and clogging of the rotor, as well as the ability of the deck to self-clean. In addition, the energy consumption of the threshing process is reduced by 8-10%.

Unique 3-point threshing system. The deck has three threshing sections, which allow you to set the threshing gap in one section. Thanks to this, the mass is threshed three times during one rotation of the rotor - in contrast to one-time threshing in traditional rotary MSUs. The same principle allows you to set larger threshing gaps.

For any grain, from barley to wheat, the threshing gap is set within 16-20 mm. No additional adjustment is required when working in any conditions.

Cleaning system.

Additional cascade. Torum uses a two-stage cleaning system. An additional blown cascade is created by another sieve. The system is perfectly balanced: the shaking board and the lower sieve move in one direction, and the massive part of the upper sieve moves in antiphase. As a result of the increase, the total cleaning area is 5.2 square meters.

A two-section powerful fan creates a uniform air flow, with air flowing not only from the ends, but also from the middle. The hydraulic fan drive provides smooth adjustment over a wide range, which is especially important when working with small-seeded crops and removing light waste.

A thoughtful approach to the non-grain portion.

Torum also demonstrates versatility when working with the non-grain part of the crop. It cuts really finely and scatters the crushed mass across the width of the header, ensuring thorough distribution of the mass across the field, which means fertilizing the soil and creating conditions for a good harvest. The device spreads straw along with chaff without using a separate chaff spreader.

• 2 operating modes (rolling/crushing);
• integrated chaff spreader;
• adjusting the straw spreading width from the cab;
• possibility of reducing the speed of the chopping drum (3400–1600 rpm).

Bunker.

The combine's grain tank with a capacity of 10,500 liters (12,000 liters for the Torum 780) is completely emptied at a speed of 105 l/s in less than 2 minutes, which makes the machine more efficient by reducing the number of cycles and unloading time.

The length of the unloading auger is increased to 5.7 m (6.8 m for Torum 780), the unloading height is 5.2 m (5.4 m for Torum 780), and the take-out angle is 105 degrees. These parameters make it possible to unload grain into any machine, even when the combine is mounted with an 11-meter header, on the move. And when harvesting rice, you can reload without leaving the check.

Threshing system

"Torum" 740 is a rotary type combine, and is on the world list of leaders in productivity. The equipment is designed for cleaning large cultivated areas and can work with any type of grain crops. During the working season, the combine is capable of harvesting about 2,000 hectares of agricultural crops. Average productivity is 40 tons of grain per hour, which ultimately gives about 300 tons per shift. Such productivity is not possible without a well-designed threshing system. It uses a rotor with a patented ADVANCED ROTOR SISTEM, which has no analogues in the world. The rotor length is 3,200 millimeters, with a diameter of 720 mm. A design feature is the movement of the deck and rotor in the opposite direction.

This solution made it possible to increase the separation area to 5.4 m2. At the same time, the coverage angle is 360 degrees, which eliminates the presence of “dead” zones characteristic of traditionally used rotary threshing schemes. Separately, it is worth noting the conveyor-free feeder chamber equipped with a beater. This allows you to work with complex crops (soybeans, corn) without losing the productivity of the combine. Now a few words about the harvesting part. POWER STREAM headers are traditionally used here, with a system for following the field topography and stone catchers. The width of the header is 6/7/9 meters; a SCHUMACHER class planetary gearbox is used as a drive. The blade rotation speed is 1,080 rpm. A trolley for transporting the header is supplied as standard.

TOP 5 high-performance grain harvesters of the Torum brand from the Rostselmash plant

The products of TPK Rostselmash are in demand because they leave no doubt about their quality and are considered competitive in the global market for specialized agricultural equipment. Not so long ago, Rostovites were able to surprise not only Russian farmers, but also global manufacturers of agricultural equipment, releasing the Torum combine harvester in 2009.

The first batch of Torum-740 combines off the assembly line, on the initiative of the Ministry of Industry of the Russian Federation, was tested in 2011, in which combine harvesters from foreign competitors took part: the American John Deere STS-9670, the Belgian New Holland CSX-7080, and the German Deutz Fahr. In the same competitive conditions, based on the results of its work, the Russian combine was recognized as the undisputed leader.

In the allotted hour, the following results were recorded:

Chassis and power plant

In the basic configuration, the Torum 740 is available with a V-shaped diesel engine YaMZ-7511 with a capacity of 400 hp. With. However, optionally, the equipment can be equipped with a more powerful GUMMINZ, providing 490 hp. With. Both power plants are eight-cylinder, with turbocharged fuel supply. For both modifications, an air cooling circuit (compressor) is used. Please note that manufacturers have abandoned the serial installation of the COMMON RAIL system, which is responsible for electronic control of fuel injection. This design does not work correctly in Russian conditions. If desired by the customer, an electronic fuel injection system can be installed optionally. By the way, the volume of the fuel tank in this model is designed for 850 liters of fuel.

The Torum 740 grain combine uses a hydrostatic clutch design, complemented by a three-speed gearbox. This gives the car the ability to change speed in the range from 0 to 27 km/h. The operating speed is adjusted steplessly. Please note that the designers have provided the possibility of installing all-wheel drive or half-track propulsion, which provides advantages when harvesting rice or working in difficult terrain.

Device

The new Russian Torum combine harvester is a class 7 rotary grain harvester. The designers claim that the productivity is about 40 t/h; and depending on the landscape and type of crop, the machine can process over 2 thousand hectares per season. The versatility lies in the fact that the equipment copes with harvesting various grains and agricultural crops (wheat, rye, oilseeds, soybeans, rice, etc.) without losses or downtime.

Advantages and disadvantages

Since the start of production, the manufacturer has expanded the model line of Torum grain harvesting equipment. Over the same few years, the advantages and disadvantages of technology have become clear.

The defining advantage of the machine is its high productivity. In addition to the grain harvesting speed stated by the manufacturer (40 t/h), the bunker unloading rate is important: Torum spends 2 minutes unloading a filled bunker (more than 10,000 l).

The large volume of the bunker allows you to work without frequent stops in the field for unloading; The combine is equipped with an extended unloading auger.

Among the advantages that are characteristic of all models and allow them to compete in the global market are:

• the ability to equip with a half-track undercarriage for working in problem and congested areas;
• the use of power plants with different power ratings;
• availability of a 2-seat luxury cabin;
• the use of different types of headers (according to the type of crop), changing them is simple;
• innovative threshing system Advanced System Rotor (the rotor deck rotates, energy consumption is reduced by 10%).

Users have virtually no complaints about the design of the machine. The list of shortcomings due to its short service life comes down to only the high cost compared to other rotary combines.

The lineup

Torum-740

The model, which took part in competitions with “foreigners,” proved its high efficiency when harvesting corn and rice, which further convinced experts of its versatility.

Technical characteristics of special equipment are presented in the table.

Constructive improvement continued. Soon the RSM-181 Torum-750 combine came off the assembly line.

Torum-750

The Torum-750 grain harvester was equipped with a 6-cylinder Mercedes engine that meets the Stage IIIa environmental standard. The basic configuration of the model includes an air compressor, an electric drive for sieves, and a single hydraulic connector. The Comfort Cab II comes with panoramic glazing and enhanced sound, dust and vibration insulation.

The model leads in fields where rice is grown; To work in “wet” checks, half-tracks are installed instead of wheels. It is possible to install additional equipment for sunflower harvesting; headers for harvesting corn can be 8- or 12-row, which allows processing up to 6 hectares per hour.

Torum-760

All technical parameters are the same as the 740th model. The only difference is in the volume of the bunker: in this model it is used for 12,000 liters.

Torum-780

This model should be compared with the 750. The length of the unloading auger for the model is increased to 6.8 m, and the unloading height is increased to 5.4 m; The offset angle for both models is the same -105°. These parameters indicate that during work on the field it is possible to unload grain into any machines, even if the combine is equipped with an 11-meter header.

Torum-785

This model ranks among the world's most productive rotary combine harvesters. Allows you to harvest various crops over an area of ​​over 2,000 hectares per season. The volume of wheat threshing per hour is more than 45 tons.

The combine can operate efficiently on a half-track, which makes it suitable for use in muddy soybean and rice fields.

The new Luxury Cab provides a comfortable working environment with less stress and fatigue. The threshing process and the operation of the combine mechanisms are continuously monitored by the Adviser III information and voice system. With its help, you can control how stable the technical process is, prevent and promptly repair unit breakdowns.

Cabin

The operator's workplace fully complies with international standards. The cabin has panoramic glazing, insulation from noise and dust, a heating system and air conditioning. It is possible to adjust the position of the steering column and driver's seat. By the way, the chair is equipped with a weight indicator: if the built-in sensor does not “feel” body weight for more than 5 seconds, the drive of the header and feeder chamber is automatically turned off. The operation of the main systems is monitored by an on-board computer, which takes readings from sensors and displays them on a liquid crystal display. The computer menu is completely Russified. The header, reel and feeder are controlled via a joystick and control unit. It is worth noting that the control unit uses a touch panel, which increases the service life of the keys.

Analogs

It is difficult to determine which of the new combines can be considered an analogue of the Torum, because each has its own purpose, which determines the demand. Among the most popular among farmers, combine harvesters of new models are most often mentioned:

1. VECTOR 450 Track - with a crawler chassis for a larger support area. This option is designed specifically for use in swampy places where rice grows and other difficult soil conditions.
2. ACROS 595. Adapted to any operating conditions. Recognized as the best technology in its class.
3. RSM 161 is a machine with a productivity of up to 40 t/h. Designed for harvesting cereals, legumes, oilseeds, cereals and row crops.
