A study to specify energy consuming components and to determine the amount of each component for a vertical narrow tool, particularly at high operating speeds, was conducted in a soil bin facility. Four main energy consuming components were assumed: 1- energy requirements associated with soil-tool interactions, 2- energy requirements associated with interactions between tilled and fixed soil masses, 3- energy requirements associated with soil deformation, and 4- energy requirements associated with the acceleration of the tilled soil. The effects of three variables, moisture content, operating depth and forward speed, were studied at different levels as follows: (1) moisture content at 14% and 20%; (2) depth at 40, 80, 120, and 160 mm; and (3) speed at 1, 8, 16, and 24 km h-1. Total energy requirement was divided into these four components based upon the procedure developed in the research.
