DEEP TILLER

摘要

agriculture. SUBSTANCE: deep tiller has stepped cutter tines inclined and arranged symmetrically one relative to the other. Cutter tines are provided with inclined platforms and are joined at their lower parts by share. Platforms have curved convex cross-section and are continuously joined to inclined side tines of lower step. Side tines are turned one with respect the other, when their positioning angle in plan is increased for each subsequent step. Width of upper step tines exceeds that of lower step tines. EFFECT: improved quality of tillage and reduced power consumption. 4 dwg
