Top-5 new grain harvesters for the farmer
Harvesting of grain, leguminous, cereal and technical crops is the final stage in the entire process of their cultivation. And in order for harvesting to take place at the optimal time, farmers need to have a suitable fleet of modern grain-harvesting equipment.
Grain-harvesting combines of most foreign companies are universal. They can be used to harvest almost all grain and oil crops, as well as seeds of grasses and small-seeded crops (rapeseed, millet, and others).
Let's consider models ofgrain harvesters, which will be relevant for domestic farmers this year and in the near future. These combine harvesters use technical solutions that increase productivity, increase yield and improve the quality of harvesting bread.
John Deere
For work in the fields of farms, the companyJohn Deere offers combine harvesters model W540. They are equipped with engines with a working volume of 6.8 liters with a turbocharging system, which develop a nominal power of 255 hp.
The threshing and separation systems of these combines use aclassical threshing system in the form of a threshing drum and a 5-key straw shaker. The threshing drum with a diameter of 660 mm and a width of 1670 mm with 10 bales and a large angle of the under-drumming provide high threshing productivity, and also allows soft threshing of crops at the optimal drum rotation frequency. The basic configuration of the thresher is equipped with a universal drum for all crops. The drumming area is 1.8 m.2, which allows you to extend the duration of threshing and carry out better separation of the grain pile.

The feature of the threshing and separation systems of W540 combines is the presence of a finger separator. The use of such an additional separating mechanism significantly improves the process of separating grain from straw in conditions of high mass humidity. With the help of fingers, the compacted wet mass is stirred, thereby releasing the grains that remained in it. In the non-working zone, the fingers of the separator are hidden, which eliminates the possibility of winding the material on the finger separator.
The keys of the 4.6 m long straw shaker have an 11-step design, thanks to which intensive separation of the grain-straw mass is ensured. The area of the straw shaker keys is 8.76 m.2. The rotation frequency of the crankshafts of the straw shaker of 150 rpm and a stroke of 150 mm ensure the maximum lowering of the straw, which ensures the efficiency of separation.
Auger conveyors evenly distribute the grain pile on the sieve of the cleaning system, even when working on slopes, increasing the overall productivity of the entire grain cleaning system. The fan has a frequency of rotation from 750 to 1600 rpm, and easily copes with even the largest flow of mass on the grate bed.
The system of processing the non-grain part of the crop creates a close contact of the straw with the knives, which improves chopping. During the operation of the shredder, 4 rows of knives ensure high-quality shredding of straw. Changing processing modes is carried out using a lever. Spreading of post-harvest residues occurs evenly over the width of the harvester grip even with a side wind.
Distinctive features of the W540 combine harvesters are reliability and ease of maintenance, high power, fuel economy and the ability to harvest a wide range of crops. It is these factors that farmers pay attention to when choosing W540 combines.

CLAAS AVERO 240/160 combine harvester
Description of models of this series on the manufacturer's website at https://www.claas.ru/produktsiya/zyernouborochnyye-kombajny/avero240-160-2017
Aclassical thresher is used on combine harvesters CLAAS - APS threshing system, which efficiently performs threshing and separation under any working conditions. The width of the thresher is 1.06 m. Thanks to APS, 90% of the grain is separated from the straw. For the remaining 10%, four straw shakers with four cascades are enough. The AVERO 160 has the same performance as a similar machine with 5 straw walkers without APS, while maintaining the compact dimensions of a 4 walker machine.
Small threshing drum: its diameter is 450 mm. MULTICROP drumming located under the threshing drum makes it easy to replace its individual segments. The angle of girth by drumming the threshing drum is quite significant - 1170. The combine can quickly adapt the drumming to a wide variety of crops, and as a result, get an optimal combination of clean threshing, careful processing of plant mass and high efficiency of separation. Adjustment of the gaps between the drum and the drum is carried out from the cabin.
The functions of a coarse pile separator are performed by a straw shaker, the length of which is 3900 mm. Four cascades are located along the entire length of the straw shaker, and serve to ensure minimal losses. The working area for separation is 4.13 m.2. In addition, the straw is intensively shaken by the controlled fingers of the exciting mechanism. The finger on top vigorously grabs the straw above each key of the straw shaker. Thanks to this, the remaining grains easily fall out of the straw.
The Slaas company considers it necessary to illustrate the design of the combine with the following diagram for the AVERO 240 / 160 model, where:

Traditional louver type sieves are used in the grain cleaning system. The area of the two-lattice state is 3.0 m.2. Centrifugal fan. The frequency of its rotation is changed with the help of an electric drive.
Thanks to the gentle threshing and separation process, the structure of the straw is completely preserved, which is important for obtaining high-quality litter. When the straw chopper is turned off, the straw is laid in rolls. If straw is used as fertilizer, then the Standard Cut straw chopper, which has 40 knives, is used.
Farmers prefer AVERO 160 combines due to high reliability in operation, as well as the presence of the APS system, which provides an increase in throughput up to 20%, while reducing fuel consumption.

Sampo Rosenlew
Sampo Rosenlew (Finland) offers Ukrainian farmers grain harvesters of the SOMIA series, which are manufactured in five models - C4, C6, C8, C10 and C12.
SOMIA combines are known for their originalharvester. Due to the fact that the harvesters are equipped with a reel of large diameter, the distance between the scythe and the auger of the harvester is large enough, which is necessary for working with long-stemmed crops. The operator controls a wide range of adjustments of the header from the cab. The harvesters have a working width from 3.1 to 5.7 m. The grain harvester has an easy installation system and fully hydraulic control. Plastic fingers of the reel and hydraulic drive of the reverser ensure stability in operation.

Description of the models of this series on the manufacturer's website at http://www.sampo-rosenlew.fi/ru/produkcia/ze-/model-nyj-rad-comia/model-nyj-rad-comia-.html
Fast and thorough threshing is provided by a threshing drum of increased strength with a diameter of 500 mm and 8 blades. The width of the thresher is 1.12 m. The use of two types of drumming is provided - grain and universal.
Separation of the threshed grain-straw mass takes place on a four-stage key straw shaker. The steps of the straw shaker have a steep slope, and the side panels are strongly serrated, which increases the quality of separation. The number of straw shaker keys on the C 4 models is four, and on the C 6 and C 8 combines – five, and on the C 10 and C 12 – six.
The total working surface of the sieves of the grain cleaning system is about 4 m.2. The upper sieve has its own characteristic design. The thresher is equipped with a straw chopper-spreader. That is, if necessary, the straw can be chopped and scattered on the field or placed in a windrow.
SOMIA series Sampo combines are equipped with SisuDiesel diesel engines of various capacities, adapted to non-European quality fuel. The cooling system of the combines is strengthened with the help of additional fans. The air return system ensures a constant flow of clean air. A belt-driven fan located outside the radiator provides effective cooling.
SOMIA series combines are light and easy to use. They are equipped with a three-speed hydrostatic gearbox with stepless gear shifting. The hydrostatic drive provides a working speed of up to 7.5 km/h, and a transport speed of up to 20 km/h. For work in wet terrain, it is also possible to install all-wheel drive on all wheels.
Sampo Rosenlew combines are traditionally created for harsh Finnish operating conditions. They easily withstand adverse weather conditions, changes in the humidity of the grain mass, loads, and temperature fluctuations. These machines don't have super high performance or throughput. They are designed for use in small and medium-sized farms and experimental plots. And in terms of reliability, harvesting quality and minimal losses, these combines correspond to the best world samples. It is thanks to these factors that they won the favor of Ukrainian farmers.
In conclusion
Grain harvesters for farms do not differ in any significant way from their "older brothers" - more powerful, with a larger harvester width and higher throughput. But smaller combines also have their advantages - they are more agile and maneuverable, which is very important when working on small areas.
Due to the fact that the loading of small combines is much less compared to large ones, their resource is much greater, and with skillful use, farm combines can be intensively operated for at least 20 years. This is confirmed by the harvesters of European farmers, which have been working successfully for several decades.
