In this study; soil-driven single-acting disc harrow and PTO-driven single-acting disc harrow machines were used. The single-acting disc harrow, which moves from the soil, was tested with two different disc diameters (610 mm and 660 mm) and three different direction angles (16o- 23o and 30o), while the single-acting disc harrow, which moves from the tail shaft, was tested with two different disc diameters (610 mm and 660 mm), three different direction angles (160- 230 and 300) and three different disc speeds (104.97-119.97 and 143.96 min-1). As a result of the treatments, the effects on soil moisture retention, deformation area, stubble burial rate and stubble amount were compared for both machines. It was determined that the cutting width and working depth increased with the increase in disk diameter and direction angle, and the deformation area increased accordingly. The lowest amount of stubble was obtained from D1N3Y3, D1N3Y2 and D2N3Y3 treatments as 20.67 g m-2, 22.67 g m-2 and 25.33 g m-2 , respectively. The highest stubble burial rate was 87.30%, 86.07% and 84.02% in D1N3Y3, D1N3Y2 and D1N2Y3 treatments. While the lowest u/v ratio was obtained from D1N1Y1 with 3.03, the highest u/v ratio was obtained from D2N3Y3 with 4.63, the lowest skidding rate was obtained from D1N3Y1 with 3.17% and the highest skidding rate was obtained from D2Y3 with 11.99.
