The approaches of functional analysis (FA) and computer-aided design (CAD) were used. A double-row disc ridger was developed and tested. While manual ridging is possible, evidence reveals that manual ridging is laborious and time-consuming hence, the need to mechanize the ridging process. Ridging has been discovered as a mechanized alternative to mounding and flat-land forms in root and tuber crop production. The decrease of tilt angle improved penetration of discs into the soil, the highest ploughing depth was recorded for the tilt angle o 15 with the disc angle o 45, which consequently led to an increase of both rear wheel slippage and fuel consumption rate. Effective field capacity was increased by 16% with the decrease of disc angle, while the width of cut, was decreased by 15%. Tractor forward speed was maintained at the most commonly used ploughing speed (9 km/h). Disc angles were assigned to the main plots whereas tilt angles were distributed in the subplots. The experiment was arranged in a split-plot design and replicated three times. ![]() This research was conducted at the Demonstration Farm of the Faculty of Agriculture, University of Khartoum to study the effect of two disc angles (43 o and 45 o) and three tilt angles (15 o, 20 o and 25 o) on tractor effective field capacity, rear wheel slippage, fuel consumption, ploughing depth and width of cut. In the DP, two angles (tilt and disc) affect tractor performance and ploughing quality. The three-bottom, fully mounted disc plough (DP) is widely used as a primary tillage implement in the irrigated sector in Middle and Northern Sudan.
