2 – PALESSE GS14; 3 – PALESSE GS12; 4 – PALESSE GS10; 5 – PALESSE GS812; 6 – PALESSE GS05 Digital values ​​in the machine model characterize the throughput of the threshing-separating device, kg per second. Only the PALESSE GS812 model has a throughput of 8 kg/s.

Technical characteristics of Polesie combines

Agricultural machinery is represented by such a huge range that manufacturers at factories offer several models of a certain brand with excellent technical characteristics. In the Belarusian city of Gomel there is a plant that produces Polesie grain harvesters. For more than 20 years, this equipment has been helping farmers in the fields and is considered one of the best in its class. The main models of Polesie combines are considered to be “Polesie KZS-1218” and “Polesie KZS 812”.

We also note that the manufacturer’s range is represented by several other models, including the GS05, GS10, GS14 and GS16 combines. The entire line of the manufacturer is distinguished by incredible characteristics; the combines are, first of all, economical, have high-quality threshing and quickly harvest the fields. Well-thought-out systems make it easy to move across fields and withstand the most difficult loads. The maximum possible comfort has been created for the driver; in addition to easy operation, Polesie combines are equipped with a comfortable cabin.

Combine harvester Polesie 812

The technical data of the combine allows it to be classified as class 4, so the equipment is capable of coping with various tasks of harvesting in the fields. It works great with a yield of 40 c/ha, where it shows good efficiency and fuel consumption. Grain collection shows excellent results, and for non-grain products there are two possible solutions - crushing and further spreading or placing straw in special windrows. The main advantages of the Polesie 812 model include:

• powerful motor with low noise and excellent performance;
• fast harvesting speed with minimal crop losses;
• high quality ground;
• inertial drum;
• excellent build quality, virtually no repair or maintenance required;
• comfortable conditions for the driver.

Based on reviews from owners, the combine performs excellently, producing the cleanest threshing possible.

Technical characteristics of Polesie 812

A 210-230 horsepower engine allowed the model to provide excellent endurance. The specified throughput rate is 8 kg/s, the threshing system is presented with 1 drum and a straw walker with 4 keys. A thresher with a width of 1,200 mm is installed, which will be an ideal solution for use in agriculture with an average yield level. All characteristics make it possible to position the combine harvester as an affordable and economical technique.

With proper operation, operation in optimal humidity and sufficient straw content, the combine is capable of producing 12 tons of grain in 1 hour of operation. For better performance, the manufacturer equipped the equipment with a 5.5 cm cubic hopper. An important indicator will be the grip of the header; in Polesie 812 this indicator is 5, 6 or 7 mm.

A special electric mechanism control is installed in the cabin, which will help regulate the concave clearance. This ensures correct threshing with maximum efficiency. Belonging to middle-class equipment, this model is equipped with a 3-cascade cleaning system. This provided a total sieve area of ​​4 sq.m. The capacity of the fuel tank is interesting; its capacity was 500 liters. The tank is created from polymers that are far superior to plastic versions and metal tanks that are susceptible to corrosion.

To use the combine in too wet soil, the Belarusian plant offers to equip the equipment with caterpillar tracks or twin wheels. Tracked modifications are quite interesting and show good efficiency in certain fields. Today, the price for a Polesie combine harvester starts at 3,700,000 rubles; a used model in good condition can be found at a price of 1.5 million rubles.

Combine harvester Polesie 1218

This model is improved and slightly superior to the Polesie 812 combine. This also confirms the attitude to class 6 and the presence of better performance. The manufacturer equips the equipment with a threshing and separating device with a stated width of 1.5 m. The device used allows it to be considered a universal assistant for various conditions and fields. The main productivity indicator is 18 tons of harvested crop per 1 hour of work. Moreover, the interesting thing is that the combine will harvest 18 tons, regardless of the condition of the grain or the condition of the field. All parts and structural parts are created according to international standards and therefore this is one of the best modern assistants in the grain production.

Characteristics of the Polesie 1218 combine

The equipment operates thanks to a diesel engine with a capacity of 330 horsepower; Polesie combines are also equipped with other engine modifications. Unlike the 812 model, the combine received an improved threshing scheme with 2 drums, as well as a modified cleaning system. It is impossible not to note the large area of ​​the separator and the accelerator system for feeding the threshed mass.

The main features of the model include:

• presence of a grain picker;
• modified soybean header system;
• grain headers with increased working width - 6, 8 or 9 m;
• special equipment for harvesting rapeseed and sunflower;

If desired, the equipment can be replenished with a special corn header. It is the large set of accessories, both in the main and in the additional kit, that gives excellent demand for the Polesie 1218 model. With a sufficiently powerful engine, it was necessary to take care of a sufficient fuel tank, so its capacity was 600 liters. In the standard version without a transport trolley, the combine harvester weighs 16.6 tons.

Driver's cabin

Modern technologies have also reached the operator’s cabin, for example, there is a large panoramic glass in front with an ideal viewing angle. Inside the cabin is quite spacious and has an area of ​​about 2.6 meters. This allows not only the operator, but also his assistant to be located in the combine.

The control of technology is interesting - it is carried out by a modern computer. The data is displayed on a large display; additionally, secondary displays that are installed on the instrument panel help display fixed data. To ensure that electronics and computers work stably, the cabin is protected and does not allow dust to enter.

Bunker Polesie 1218

The presented model is ideal for large harvests, which can be easily handled. A grain bin with a large volume of 8 cubic meters also helps to ensure this. The manufacturer decided to use such a volume not by chance, because Kamaz vehicles with a capacity of 16 cubic meters typically pick up grain. That is, 2 filled bunkers will be enough to fully load the Kamaz without wasting time on idle equipment.

Combine Harvester Polesie 1420 (GS14)

One of the latest and most powerful models, which was produced not so long ago, but has an engine with a power of as much as 400 hp. Polissya 1420 is positioned as a high-performance equipment for harvesting large grain harvests. It is also ideal for other threshed crops and is therefore widely used on farms throughout Europe.

The GS14 model has a number of distinctive advantages:

• many different headers, both in basic and additional configurations;
• threshing using a two-drum circuit;
• six-key straw walker with an area of ​​7.5 m2 for separating the remaining grain;
• modern comfortable cabin with computer control;
• width of the threshing apparatus 1,700 mm;
• excellent productivity of 20 tons of grain per hour of operation.

The Polesie brand products from the Belarusian plant are represented by several models, each of which is different and presented for a specific yield. We have presented only 3 interesting and most popular ones, but farmers from all over Europe actively use other modifications and only respond positively to this technique.

Indicators of the advantages of Belarusian agricultural machinery

The line of these harvesting machines is designed for harvesting grains, as well as rapeseed, buckwheat, soybeans, corn and other crops. As production tests have shown, the effective system for cleaning the grain mass gave results at the level of the best in the world. Even specialists from American and Israeli agricultural machinery factories were forced to accept the results of comparative production tests.

The table shows that the main characteristics of the Polesie combine are at the level of leading manufacturers. An important factor that determines the choice of many farmers to give preference to Belarusian agricultural machinery is the price. For these machines it is an order of magnitude lower than that of equipment from non-CIS countries.

The GomSelmash holding provides long-term guarantees for all equipment produced by it. Spare parts and equipment, if retrofitting and repairs are necessary, are supplied as quickly as possible. Today, in some regions of Russia, service points have been created where maintenance and repairs can be performed. To reduce buyer costs, service can be ordered on the territory of your farms. Specialists will arrive on site and carry out a series of preventative maintenance according to the maintenance plan.

Repairs can be carried out similarly if units are damaged during operation. Major repairs are carried out only in service centers. As practice shows, today Polesie combines are in an advantageous position in comparison with other similar agricultural machines.

About the manufacturer

Belorusskaya began its activities in the production of such equipment more than 10 years ago, and since then their machines have won the trust of farmers in Ukraine, Russia and some other countries.

The manufacturer is Gomselmash , which produces really high-quality products, thanks to which Polesie combines are always in demand. In addition, this manufacturer somehow wins in price, because goods from Belarus are often cheaper than competitors.

In general, it is worth noting the high quality of all mechanical engineering equipment from Belarus. A striking example is the MAZ 7907, MAZ 500, MAZ 541 and MTZ 1221.

It is for its affordability and excellent performance that thousands of farmers and agricultural enterprises across the country appreciated all the advantages of the new Polesie combine harvester. In addition, it is easy to find parts and high-quality service for equipment from this company throughout Russia, because the company is domestic.

In addition, the parts are quite affordable, so repairing or replacing spare parts will not be a waste for you.

A distinctive feature of this manufacturer is that Polesie offers farmers several models of grain harvesting machines.

This is done so that everyone can choose exactly the technology that best suits their needs.

Of course, every Polesie car is of excellent quality and is guaranteed to serve you for several dozen seasons. All the advantages in the operation of the Polesie combine harvester can be seen in the video materials published in the article.

Geography of sales of Polesie combine harvesters

In 2020, interesting data were published on sales of Belarusian-made agricultural machinery to the CIS countries, and in particular Polesie combines:

• Russian Federation – 58 pcs.;
• Republic of Kazakhstan – 22 pcs.;
• Ukraine – 6 pcs.;
• Republic of Uzbekistan – 17 pcs.;
• Kyrgyzstan – 9 pcs.

Comparing data over the past five years, we can note positive sales dynamics. Every year there is a certain increase, which indicates the growing popularity of Polesie combines.

Tip # 1. Polesie combines are provided with service centers in many CIS republics, so they have an advantage in service compared to agricultural machinery from other manufacturers. It is easier and cheaper to carry out repairs with the involvement of specialists from the service department than to carry out repairs on your own.

Main buyer mistakes:

• Mistake #1. You purchase a combine harvester only with the widest header for a given model, but during operation it turns out that some fields have a side slope of more than 8°. The header becomes detached from the support shoes.
• Mistake #2: Some buyers use a food processor to harvest rice. But to equip agricultural machines, a tracked drive from the SK-5 Niva and Yenisei 1500 combines is used. In this case, there is a need to regrind the landing bushings. As a result, the manufacturer's warranty on the purchased equipment disappears.

Operation of the Polesie combine harvester

As has already been emphasized, Belarusian equipment can be operated in any climatic conditions and in any weather. The machines are capable of reaping and threshing wet and laid-down grain crops, moving on viscous soils, while ensuring high grain quality.

Important!
The efficiency of Belarusian combine harvesters meets modern world standards.

Fuel consumption rate

The amount of fuel consumed to operate a combine harvester depends on the power of the engine installed on a particular model, as well as on the operating conditions of the unit. For example, the most popular GS12 model consumes on average about 26 liters of diesel fuel per hectare of cultivated area. With a rated power of 330 horsepower, specific fuel consumption is 206 grams per kilowatt-hour.

Features of the devices of combine harvesters "Polesie" ("PALESSE")

Let's take a closer look at the design of grain harvesters.

Harvester headers "Polesie"

Headers for Polesie combines operate in a similar way to headers for Russian-made combines. They include a number of basic mechanisms:

• a reel that lifts laid grains, directing the stems to the cutting elements;
• mower that mows grain mass. The teeth perform reciprocating motion driven by a planetary gearbox;
• augers that collect the mown mass to the center of the header. They have a chain drive from V-belt variators;
• finger conveyor, which ensures the supply of mass to the inclined conveyor;
• an inclined conveyor that supplies grain mass for processing into a threshing and separating device.

The photo shows side cutters, a cutting device, augers, a finger conveyor and an inclined conveyor . The plant produces a series of headers with a working width from 4 to 9 m. All types of headers have support shoes that allow you to follow the field surface when harvesting. When moving between fields, it is recommended to disconnect the header from the combine, and then transport it in the form of a trailer, following the combine.

Threshing device of combine harvesters "Polesie" ("PALESSE")

The Palesse GS16, Palesse GS14 and Palesse GS12 models use a double-drum threshing system. Drums of different diameters:

• the first beater drum with a diameter of 600 mm;
• the second drum has a diameter of 800 mm.

Sifting decks are located below, through which the grain is sifted down, and the straw with the remaining seeds is moved further to be shaken off. The rotation speed of the reels is such that the linear speed on the first reel is lower than on the second. Therefore, the incoming mass is stretched. Therefore, the main part of the grain spills on the second drum.

Beating drums of the threshing and separating device of Polesie combines with high throughput. In addition to the drums, cutting decks are shown, through which the threshed grain is sifted

The PALESSE GS10, PALESSE GS812 and PALESSE GS575 low-capacity combines have one beater drum installed. Its diameter is 800 mm. The length of the drum corresponds to the width of the receiving chamber. Different models have different widths, which explains the different throughput.

Single-drum threshing device for Polesye combines. The beater drum and perforated decks are the main elements of the thresher

Separating devices of combine harvesters "Polesie" ("PALESSE")

The PALESSE GS16 model uses the principle of rotary separation. The cylinders, similar to beating drums, are wrapped around decks. The cylinders rotate towards each other. The grain mass with straw is thrown onto the decks under the influence of centrifugal force, and then falls back onto the beaters.

The beaters themselves are small blades directed at an angle of 5...7 ° towards the exit from the separator. Due to this, forward movement occurs. The remaining grain is sifted through the decks.

The use of the rotor principle makes it possible to achieve high cleaning efficiency of the mass. As practice shows, the energy intensity of this separation principle is higher, and at the same time a high degree of purification is observed. No more than 1% of the grain remains in the heap of straw.

Rotary separator of the PALESSE GS16 combine. There are two cylindrical beating rotors, they are wrapped with mesh decks

The remaining models of Polesie combines are equipped with traditional push-button straw walkers. Only the PALESSE GS812 and PALESSE GS575 models have four keys; the PALESSE GS14 has six keys, and the others have five. The settings and adjustments were developed for the first combine harvesters, implemented on American-made John Deere models, and then it was repeated many times on other similar combines. The difference is only in size, but the general principle is the same. Each key is driven by rotation of the crankshaft. Each knee is controlled by its own crank. Therefore, one goes up and the other goes down. The rotation frequency is high, with a relatively low amplitude. Therefore, the straw walker vibrates at a high frequency.

By this time, the straw is already noticeably crushed, but the particle size is several times larger than the grain size. Therefore, grains with a large mass fall down, and the straw goes out onto the fan. Then it is thrown out.

The PALESSE GS812 model can additionally be equipped with an automatic stacker. It is available upon special order from the buyer. Some livestock farms have developed a technology for increasing the nutritional value of straw by barothermochemical processing of straw (farms in Crimea), which is why they are the main customers of this option for combines.

Design and operating features

The Polissya KZS 812 series has a standard design, including a chassis, threshing system, loading hopper and cabin. The combine represents the category of grain harvesting machines with one drum, a straw walker and a beater. Due to ease of maintenance and technological reliability, such a scheme has received the greatest recognition in Russia.

The undercarriage is designed to withstand tough conditions. As an option, it is possible to install a caterpillar drive with reinforcement or twin wheels (KZS 812S). This modification is suitable for areas with wet and unstable soil.

The cleaning process in Polesie KZS 812 is carried out in several stages. The working parts of the combine are involved in the process:

• reaping part. The base for the model are Gomel headers of various widths. They are protected from mechanical damage by hydropneumatic accumulators. The reaping part of most versions is equipped with a relief copying mechanism, ensuring maximum productivity. A planetary gearbox is used to drive the reaping apparatus. The cutting apparatus contains stamp-welded fingers with lower and upper cutting edges and a system of alternating segments. This ensures a clean cut and ensures cleaning. Additionally, Polissya KZS 812 can be equipped with equipment with rapeseed reflectors and fingerless side dividers for harvesting rapeseed, a system for collecting corn (cob separator, stalk chopper, replaceable concave) and other units;
• inclined camera. The element ensures uniform supply of mass for stable threshing;
• threshing and separation system. The PALESSE GS812 thresher is equipped with an inertial drum, which improves the quality of harvesting crops with medium straw content. The latest versions of the combine are equipped with a Big Drum threshing apparatus, equipped with a modern high-inertia drum. The operator can set the concave clearance directly from the passenger compartment. When an element is clogged, an emergency concave release system is used to restore threshing stability. The presence of an autonomous pre-threshing device eliminates the possibility of overloading the thresher. Grain separation is carried out using a 4-key cascade-type straw walker with a large area. Due to the adjusted step difference, optimal separation of the residual mass occurs. A 3-cascade cleaning system with sieves with an area of ​​3.86 sq.m and electrically controlled cleaning fan guarantee high quality of the final product;
• large bunker with quick unloading.

The cabin of the Polesie KZS 812 combine harvester is large and is designed for 2 people. It has panoramic glazing and increased vibration and noise protection. The air conditioner allows the operator to work in comfortable conditions in any area. The combiner's working area is designed in accordance with the latest advances in ergonomics. The adjustable seat adapts to any operator configuration.

Monitoring the main systems and warning about problems are the responsibility of the on-board computer. When starting the engine, the system checks the integrity of the working mechanisms and their serviceability. In case of problems, information is instantly sent to the operator. The system is also responsible for selecting the optimal operating mode, taking into account the type of crop and external factors, adjusting the air cleaning force, the level of opening of the sieves, the speed of the threshing drum and other parameters. This ensures maximum quality of operation.

The cost of the new Polesie KZS 812 combine harvester produced by Bryanskselmash starts from 4.9 million rubles (modifications KZS-812-27 and KZS-812-22). A similar model produced by the Belarusian enterprise Gomselmash is available at a price starting from 3.6 million rubles (basic version KZS-812).

Price tags for used Polesie KZS 812 combines in good condition (2010-2013) are 1.7-2.5 million rubles

Features of servicing combines "Polesie" ("PALESSE")

During the harvesting period, maintenance activities are required to ensure uninterrupted operation of the combines. Agricultural equipment manufacturers have developed special maintenance cards for their machines

To perform maintenance, all combines are equipped with tool sets, as well as auxiliary devices for lubrication and monitoring of main systems and assemblies.

Possible errors during operation:

• Mistake #1: Some farmers neglect daily maintenance. As a result, the combine is left without coolant in the cooling system, and the engine fails.
• Mistake #2: Trying to save on oil for hydraulic drives results in loss of efficiency when raising and lowering working parts. This leads to damage to the header. A sharp lowering of the header when moving between fields is especially dangerous.

V-belts are adjusted in a certain sequence:

1. A ruler and a dynamometer are taken from the spare parts kit.
2. The belt between the pulleys is pulled with a force of 100 N.
3. The belt deflection is measured.
4. The resulting value is compared with the tabular data.
5. If necessary, the required deflection is set using tension rollers.

Combine harvester KZS-1218A-1 “PALESSE GS12A1”

Buying a grain harvester KZS-1218A-1 is a smart choice

This combine is one of the best in its class and occupies a worthy place among world analogues. The operational and technological characteristics of the combine have a good reputation both in our country and abroad. Moreover, unlike foreign analogues, you can buy a combine harvester of this model quite inexpensively. It is cheaper, both in cost and in operation.

KZS 1218A1 grain harvesters: features

The combine harvester of this model is a logical development of the most popular KZS-1218, but at a different stage of technical development and design thought. The new KZS 1218A1 grain harvesters have received a number of innovative solutions. Almost all basic indicators have been improved. First of all, it makes sense to consider the changes that were made by the designers.

• The reliability of the feeder chamber and the ease of its maintenance have been increased. The designers have achieved a reduction in dust levels. For this purpose, a 4-ribbed belt drive, a dust extractor and IVIS conveyor chains were installed.
• The volume of the grain storage bin Polesie KZS 1218 has been increased to 9 m3. This allows for high shift productivity.
• The safety of unloading wet grain has been increased and the formation of arches has been eliminated. A vibrating machine installed inside the bunker effectively copes with this task.
• The efficiency and safety of grain and corn harvesting in high humidity conditions has been increased. This is achieved by a reinforced shake board.
• The new KZS 1218A1 grain harvesters are supplied with plastic side hoods. Decorative fences are installed on the hood of the salt walker. The designers also replaced the masks and bumper on the cab subframe and transport headlights. The finishing inside the cabin has become even more practical and durable.

Chassis KZS 1218 a-1 palesse gs12A1

The efficiency and reliability of a combine harvester largely depends on the efficiency and reliability of its chassis. Designers are well aware of this, so they always strive to make the chassis elements as practical and durable as possible. In this regard, this model compares favorably with its analogues, so it is worth buying a combine harvester of this model for those who need reliable equipment that will not let you down.

• Optionally, you can install three types of engines. First of all, this is YaMZ-238DE-22. In addition, the TAD 853 VE Volvo and OM926LA3A engine are installed. All three options are equally reliable and durable, capable of coping with tasks under heavy load for a long time.
• The 600-liter fuel tank of the Polesie KZS 1218 combine is protected from corrosion because it is made of modern polymer materials. Refusal of a metal tank makes the combine more reliable and durable. The pumping system is not clogged with rust, so it wears out much longer.

Cabin and on-board computer Polesie KZS 1218

Operator fatigue can lead to serious errors that delay work deadlines and threaten to damage equipment. To avoid such problems, the KZS 1218 a-1 Palesse gs12A1 is equipped with a truly comfortable cabin and an on-board computer.

• The spacious cabin has large panoramic viewing windows. The operator can keep an eye on everything going on around him.
• The adjustable backrest of the chair can be adjusted to suit any body type, making work even more comfortable. The height of the control handle is adjusted along with the backrest.
• The control handle contains quick response functions: the speed of movement of the combine, the direction of its movement, control of threshing and unloading speed.
• The on-board computer Polesie KZS 1218 allows you to quickly test the system for faults. The operator will immediately know about any potential problems.

Equipment Polesie KZS 1218 a-1 Palesse gs12A1

The efficiency and functionality of the combine can be expanded with the help of accessories to perform different types of work. In addition, if necessary, this model of combine can be equipped with imported components.

• Together with the Mercedes engine on the KZS 1218 a-1 Palesse gs12A1, you can now install a multifunctional connector for connecting the thresher with the Faster header. Use hydrostatics from Sauer Danfoss. And other foreign-made components for various purposes.
• If necessary, you can install a high-capacity air filter from MANN-HUMMEL, made in Germany. This can be very useful for the southern regions of our country and the Altai Territory. This filter increases the time between maintenance.
