                            <p>In this study, the effects of different direction angles of disc harrow on draft force requirement and some soil physical properties of a trailed type disc harrow with tandem structure in loamy soil conditions were determined. For this purpose, with the discs in the front batteries in a fixed position of 14o, and the discs in the rear battery, 14o, 17o and 20o direction angles were considered as A, B, C and D (control) applications, respectively, and the draft forces were determined. In addition, in the experiment, the mean weight diameter, soil bulk density and soil porosity were determined. According to the results obtained, the disc harrow draft power requirement increased with the increase in disc angle. For A, B and C applications, 10.51, 11.12 and 11.56 HP draft power were determined, respectively, and the difference between A and C applications was found to be significant. While the difference between the soil bulk density depending on the applications was found to be insignificant, the soil penetration resistance increased with the increase of the disc angle. Mean weight diameters for A, B, C and D applications was found to be 10.12, 11.61, 11.60 and 12.53 mm respectively and no statistical difference could be detected between them.</p></trans-abstract>
