This study investigates the structural and operational parameters of a serrated share (tooth-edged ploughshare) used in flat tillage ploughs that operate without forming furrows. The aim is to optimize the geometry and arrangement of serrations to minimize soil resistance and improve energy efficiency. Experimental results indicate that serrated shares reduce soil bulk density by 8–12%, decrease draught resistance by 10–15%, and increase fuel efficiency by up to 1.1 L ha⁻¹ compared to conventional smooth shares. The findings contribute to the design of energy-saving soil tillage implements and support sustainable land management practices in arid and semi-arid regions.
