Abstract
Furrow formation is one of the most labor-intensive operations in potato cultivation technology. The article discusses the justification and determination of furrower parameters of the potato planter. Analytical dependences of the height of the junction point of the disks and the width of the furrow bottom are obtained, taking into account the technological parameters, its design features and the physical and mechanical properties of the soil. Potatoes are planted in the usual way. The main row spacing in our country is 70 cm. However, in areas of high humidity and in irrigated areas, wide-row planting with a row spacing of 90 cm is used. In some areas of the European part, in arid areas, potatoes are planted with a row spacing of 60 cm. By the time of harvesting, the potato field has a ridged appearance, obtained as a result of hilling, where the height of the ridges is 11…20 cm. The angle of the row seed drills is that the vanishing point of the coulter rises above the bottom of the furrow by 6.3 cm. With an increase in the angle of entry of the coulter into the soil from 2° to 11°, the depth of the coulter travel increases. At angle values from 3° to 8°, the stroke depth approaches the optimum (12…18 cm).
