An indoor soil bin was developed in this study for testing soil-engaging tools. The design criteria included that the soil bin had to be compact, well controlled in its operational parameters, instrumented to measure soil cutting forces, and be safe to operate. The test tool could travel at any specific speed, up to 8 km h-1. A compact dynamometer was designed for the soil bin for measuring soil cutting forces in three directions. The calibration results of the dynamometer showed a linear relationship between the loads and the output voltages, with coefficients of determination of 0.99. The cross sensitivity between the directions was from 0.31% to 4.7%. The soil bin and the dynamometer were tested using a disc operated at three values of tilt angle of 0°, 10°, and 20°. The test results showed that the soil bin allowed precise control of the tool travel speed and working depth in the designed ranges. Forces of the disc had an increase in vertical and lateral forces, and decrease in draft force, with the increase in tilt angle. These trends are in line with other studies in the literature. The results proved the full-functioning status of the soil bin and the dynamometer. Keywords: Calibration, Design, Disc, Dynamometer, Soil bin, Test, Tilt angle.
