Kinematics of the rotary working body for harrowing crops.

When working with a rotary harrow in the spring on winter crops, it is necessary to ensure high-quality soil crumbling, since the soil crust formed on the surface prevents the flow of oxygen and moisture to the plant. Also, according to the technology, before harrowing, spring fertilizing with mineral fertilizers is carried out, after which they are embedded into the soil with rotary hoes, but the fertilizers can evaporate if they are poorly embedded. Therefore, the problem of entering the needle into the soil at 90 degrees to form a hole with minimal evaporation of fertilizers is considered. [ABSTRACT FROM AUTHOR]
