It is possible to improve the quality of agro-technical care of plants in arboretums by ap-plying the rotary working bodies in the form of needle-shaped discs which thanks to a combina-tion of the unit translation with their free rotation, provide qualitative opening of the soil along with weeding. The main purpose of the needle-shaped disks is to destruct the soil cover and weeding in the early stages of a plant growth.
