The effect of operational parameters on selected tillage tools or tines were studied by using instrumented soilbin at Department of Farm Machinery and Power Engineering, College of Agricultural Engineering, Raichur (Karnataka). The experiment was conducted in sandy clay loam soil to study the effect of variation of forward speed (3, 4 and 5 km/h), operating depth (5, 10 and 15 cm) and type of tools (Sweep-1, Sweep-2 and Shovel-1) on draft, specific draft, soil disturbance parameters and tool width to furrow width ratio. The test was conducted in a 21 m long, 2 m wide and 1 m deep soilbin. By altering the combination of speed and operating depth, the response of all parameters were studied for each tool. The results obtained after each run were tabulated and further analyzed through Design Experts 7.0.0 software for optimization of data. It was observed that, at 5 km/h forward speed and 15 cm operating depth, the Sweep-2 gives the maximum value of draft (1,208.33 N). Similarly, at 5 cm operating depth and 3 km/h forward speed, Shovel-1 gives the minimum value of draft (193.67 N). The maximum value of specific draft was observed for Sweep-1 (15.17 N/sq.cm) at depth-1 (5 cm) and speed-2 (4 km/h). Similarly, the minimum value was observed for Shovel-1 (1.51 N/sq.cm) at depth-2 (10 cm) and speed-1 (3 km/h). For Sweep-2, the specific draft values observed were greater than Shovel-1 and less than Sweep-1. The effect of depth of operation of the different sweeps and shovel on soil disturbance was observed for a forward speed of 3, 4 and 5 km/h. The width of the tool strongly influenced the soil disturbance parameters as they all increased as the working depth increased but less proportionately. In this experiment, the minimum value of the tool to furrow width ratio was observed for Sweep-1 (1.36) at speed-2 and depth-3, whereas the maximum value was observed (3.56) at depth-1 and speed-1.
