A study Some Technical Indicators Under Impact Tillage Depth and Disk harrow Angle of the Compound Machine

Abstract

The research included studying the effect of different plowing depths (10, 20and30) cm and three angles of the disc harrows (18, 20and25) when they were combined in one compound machine consisting of a triple plow and disc harrows tied within one structure. Draft force, fuel consumption, practical productivity, and resistance to soil penetration. The results indicated that the plowing depth and disc angle had a significant effect on all studied parameters. The results showed that when the plowing depth increased and the disc angle increased, leads to increased pull force ratio, fuel consumption, resistance to soil penetration, and reduce the machine practical productivity.
