“…Registered damage to cultivation tools working in stony soils or in the conditions of forest clearing requires changes in design, strength, and geometric parameters [8]. In subsequent studies [9], four types of tools were used, i.e., disc plow, cultivator disc, sweep tool, subsoiling tool, and it was found that the greatest reactions were recorded during the frontal defeat of a stump by a disc plow; and in the case of a side impact with a stump, by a subsoiler. To develop practical tools working in soils with hard obstacles, obstacle-tool interactions and the ability to overcome various obstacles must be studied.…”

The kinetics and dynamics of the stiff and flexible tines with the duckfoot and the coulter after impact with stones embedded in compacted soil were examined. The beak of the duckfoot was positioned in the axis of the row of stones embedded in the soil at the depth of stones thickness. The coulter covered the stone or impact the edge of the stone halfway along its length. The tools worked at a speed of 0.83–2.22 m·s−1 and a working depth of 0.05–0.10 m. The results of specific parameters were compared to the response of the tools to loads in soil without stones. For both soil conditions, the kinetics of the flexible tine was 24 times more reactive, and the dynamic loads were two times lower than for the stiff tine. The responses of both tines were suppressed along with the working depth because of the more favorable place of impact of the duckfoot beak with the stone. Along with the working speed, for a stiff tine, the specific accelerations decreased significantly, by ten times, and the specific forces increased slightly, by 1.6 times. Among the two systems of setting the coulter, the impact of the cutting edge of the coulter with the stone in the middle of its length was more unfavorable than the work of the coulter covering the stone.
