Abstract:
The experiment was conducted at the College of Agricultural Studies Farm of Sudan University of Science and Technology-Khartoum North in 2019. The nature of the Soil on the farm was found to be light clay soil. The experiment aimed to study the effect of two disc angles (40°and 45°) and two tilt angles (150and 25°) on effective field capacity, field efficiency, tractor wheel slip and fuel consumption rate using a mounted disk plow. The results showed that increasing the disc and tilt angles of the plow significantly (p<0.05) increased plow field capacity and field efficiency. Increasing disc angle of the plow significantly increased tractor wheel slippage, while the minimum values of the disc and tilt angles gave a low rear wheel slippage (13.1%). Increasing tilt angle and disc angle of the plow led to increase in fuel consumption rate. Moreover, results showed that 5.6 L/fed was the optimal consumption rate, which from the combined effect of 40° disc angle and 15° tilt angle.
