Results of laboratory studies of the universal seeding section with interchangeable coulters
The article presents the results of experimental studies of a universal sowing section with replaceable disc, tine, anchor and keel coulters, designed for sowing grain and fodder crops using traditional, soil-protective, minimum and zero technologies. In the experiments, the traction resistance of different types of coulters, the reactions of the soil on the supporting and press wheels, and the force of the spring preload to ensure a given depth of coulter travel were determined. The results of the experiments showed the operability of the sowing section at various speeds of movement and the depth of the coulters, and the adequacy of the results of theoretical studies to the real process.
