Increasing the efficiency of use of wheeled harrow units in regions of risk farming

Crop yields largely depend on the quality of the soil prepared for sowing. At the same time, one of the most important field operations is harrowing, with the main technological parameter of harrowing is the depth of processing of the fertile soil layer. Failure to do not have the necessary depth of processing leads to a decrease in yields, and the excess - to additional energy costs, and therefore to increase the cost of a unit of the resulting products. As you know, the main parameter influencing the depth of processing is the weight that falls on the working organ of the harrow. This article proposes a device that has obtained a patent for the intellectual property of the Russian Federation, allowing to regulate the weight of the working organ of the harrow, due to its optimal redistribution within the machine-tractor unit (MTU), and the theoretical and experimental results of the experimental harrowing unit are provided. The results suggest that the proposed solution is highly effective, which provides as an opportunity for quality pre-planting treatment, and contributes to the compliance with the necessary agro-technological requirements for the harrowing process.
