What is a combine harvester for?
One of the most labor-intensive activities in agriculture is grain harvesting. Fortunately, a large number of different grain harvesters have appeared, such as the Niva effect combine, a trailed combine, and a mini grain harvester, which will clear the field in a few days without any effort on the part of the farmer.
Combine harvester
As a rule, such devices not only remove grain, but also partially clean it, facilitating its further processing. That is, it speeds up the production of bread products, which is also very important. They can work on absolutely any soil thanks to their excellent cross-country ability, so even sticky soil will not be a problem.
For those farmers who own fairly large fields, the purchase of grain harvesting equipment will be more than relevant.
But you need to purchase exactly the kind of machine that will be the optimal solution for all the tasks that the landowner sets for himself.

Design and service features
Polissya KZS 1218-29 has a design consisting of a thresher on a self-propelled wheeled chassis and a trailed mechanism (reaper) used for cutting stems. The chassis is represented by a driven front and driven rear axle. The chassis houses the power drive, engine, suspension parts and grain separation mechanisms. The combine uses wheels with 18.4 R24 (steer axle) and 30.5L R32 (drive axle) tires.
The model combines advanced technologies, automated control devices and a classic grain threshing scheme.
Main functional elements of the combine:
- unified ZhZK headers (manufacturer – Belarus) with different processing widths, allowing you to cut problem grains with maximum quality. The technique uses the entire working width of the header, providing a uniform cut that does not depend on the soil profile. The use of a hydromechanical relief copying device improves efficiency indicators. The reinforced pipe design of the rake eliminates the possibility of straw and other non-grain parts wrapping around the reel. The operator can adjust the rotation speed of the reel, controlling the incoming flow of grain mass. The basic set of the header for the Polesie KZS 1218-29 series includes a trolley that allows you to deliver units for the combine;
- The inclined chamber receives the compressed mass, after which two chain-plate conveyors direct it to the threshing device. The feeder chamber has a reverse function, which facilitates maximum cleaning of the device;
- The threshing mechanism is responsible for separating the accompanying mass from the grain. Combined combing, impact and rubbing effects on the stem mass provide high-quality separation. The combine uses a 2-drum threshing system. The drums are driven through a V-belt variator, supplemented with a tension unit. The accelerator drum with a coverage angle of up to 213 degrees increases the productivity of the combine. This feature reduces the load on the main threshing drum and improves the quality of the grain at the exit.
- The cleaning unit is built according to a cascade scheme, which has confirmed its effectiveness on other Polesie combines. The separation of the grain heap is carried out by passing it through a pre-threshing device and a system of sieves that remove excess particles with an air flow. A powerful fan, adjustable from the cabin, ensures proper cleaning efficiency;
- straw walker driven by cardan shafts and 5 keys, made in a cascade version. The mechanism performs the final separation of the straw heap leaving the cleaning zone. Grain is supplied to the bunker by screw-type elevators-conveyors. The straw walker is complemented by a built-in chopper with 80 rapidly rotating knives that scatter the straw over the field area. If necessary, the operator can select the windrow laying mode for this device;
- large volume bunker. The capacity of the bunker is specially designed to completely load a KamAZ vehicle twice, ensuring uninterrupted removal of harvested grain and eliminating downtime. The bunker is equipped with windows for sampling, a screw elevator for unloading and filling control mechanisms.
Polissya KZS 1218-29 is equipped with a modern cabin with heating and ventilation units. Large panoramic glass provides good visibility. The interior of the combine is quite spacious (over 2.6 square meters) and allows the operator to feel as comfortable as possible. Moreover, an assistant combine operator can be accommodated inside. The operating mechanisms are controlled by the on-board computer and the BIUS-03 system. Node data is displayed on a screen with an anti-reflective coating. Information that remains unchanged is shown on secondary displays mounted on the control panel. To extend the service life of complex electronics, the cabin is equipped with an improved dust protection system.
Polissya KZS 1218-29 is a universal machine designed to work with various crops. In the stock configuration, the functionality of the combine is limited, but additional adapters, windrow pick-ups, headers and other mechanisms allow you to harvest soybeans, corn, rapeseed, sunflower and other crops.
Polesie KZS 1218-29, although it has many advantages, has its own operating features and disadvantages:
- The most “weak” point of the combine is the belt, which is regularly wiped. It is recommended to use the original element for replacement as it will last longer. Various types of belts are used for the cleaning system, compressor and hay chopper;
- equipment sieves regularly catch on each other;
- On-board computer failures often occur;
- Stock tires wear out very quickly.
