Soil compaction is one of the major problems facing agriculture today because it increases soil strength and decreases fertility. Modifications to soil decompaction equipment, active bodies and management systems have been shown to provide opportunities to significantly reduce the incidence of compaction. The topic addressed in this paper represents a method of computer-aided design (CAD) combined with computer-aided engineering (CAE) used in the analysis of the choice of the optimal constructive variant to reduce the forward resistance forces of a chisel-type active body intended for soil work equipment without turning the furrow, in order to eliminate hardpan as well as deep compaction. Based on the resulting data, mass/drag coefficient ratios were determined for three analysed configurations. The comparison of these indicators led to the choice of the optimal constructive variant in the sense of the most performing, in order to reduce production costs with maximum efficiency.
