The motor-cultivator operation principle unique in own way became peculiar business card of the unit for a long time. Successfully carrying out difficult processes of agriculture which not always normal motor-blocks can do, he is the effective assistant in household.
Motor-cultivator – one of modifications of the motor-block which main function is cultivation of the soil. Process of cultivation represents loosening of top layer of soil without layer turning.
By means of motor-cultivator it is possible to execute the following operations: plowing, breakdown of blocks of the earth after plowing, earthing up, uniform mixing of the soil with the introduced organic and mineral fertilizers, loosening of soil crust, destruction of weeds and roots. The number of the carried-out operations in general depends on motor-cultivator model.
Externally the design of motor-cultivator is similar to the motor-block, they are quite often confused with each other. The difference consists in principle operation of the unit, set of the carried-out operations, the motor-block is more universal, than motor-cultivator. And the cultivator is in many respects obliged by the creation to the motor-block. At installation on the motor-block of mills for cultivation it has become clear that, rotating, the mill, interacting with soil, creates running draft of sufficient force for independent movement of the unit on earth surface. At the same time the cultivator is capable to maneuver easily among densely planted bushes and trees. Thus there was new operation principle of the mechanical device: the motor-cultivator course operated in any direction. In need of operation of cultivator in other purposes (towage of plow or the trailer), mills easily act and established wheels.
Mainly all modern models of motor-cultivators motorizirutsya by four-stroke gasoline engines. Extralight models of cultivators on which two-stroke engines are installed became exception. The reason for that became: lightweight, simple design and rather low cost of the engine. As for profitability and ecological purity, two-stroke engines considerably are inferior to technically difficult and more advanced four-stroke motors. Now the market of small-sized agricultural machinery is literally crowded with offers of motor-cultivators of a different type. When choosing the unit it is worth studying attentively technical characteristics, parameters and completeness of the device.
