Four types of narrow tines with different widths but the same length of 1 m were analysed. Field trials were conducted in clay loam soil in a factorial experiment based on a randomized complete block design with three replications. The soil moisture was 15%, and four tractor forward speeds of 1, 1.5, 1.8, and 3 km h-1 and tine widths of 2.5, 3, 3.5, and 4 cm at working depths of 10, 20, 30, and 40 cm were investigated relative to the required draught. In order to investigate the effect of the depth/width ratio and the speed of the narrow tillage blade on the draught force, a three-dimensional model was prepared and tested at different settings. The results of the draught force applied to the blade were recorded. Increasing the forward speed showed a significant effect on increasing the stress exerted on the soil, but increasing the depth/width ratio reduced the stress created in the soil. It was found that the forward speed, tilling depth, and tine width increment exerted a significant effect on increasing the required draught.
