Results of studies of a potato digger with rod burning working bodies

Abstract

Abstract The article presents the results of experimental studies of a potato digger with standard (control) and bar undermining working bodies (experience). A relationship has been established between the speed of the harvester and the loss (number of seedlings) of potato tubers for various harvesting options. The aggregate composition of the soil is justified when using the above potato digger. It was found that an increase in the speed of movement of the potato digger by 1 km/h leads to an increase in losses of potato tubers in the control variant by 2.7 pcs/m. In the experimental version, it leads to a decrease in losses of potato tubers by 2.0 pcs/m. Besides, in the control variant, an increase in the speed of movement from 1.8 to 3.4 km/h led to an increase in losses of potato tubers by an average of 4.7 pcs/m, when in the experimental variant the casualties were 4 pcs/m. However, with the pilot version, the speed increase was from 2.6 to 3.4 km/h, the losses decreased by an average of 1.0 pcs/m, with a parallel rise in potato digger productivity.
