In this study, an indoor soil bin is developed for experimental soil-machine investigations. The soil bin was consisted of five main components, i.e., a fixed soil tank, a moving carriage, drive power transmission system, soil processing device, and control unit. The soil processing device consisted of a roller with variable weight for soil compaction. The moving carriage and the roller were driven by an electrical motor using a chain and sprocket system. The control unit included a load cell, inverter, and interface. For system performance evaluation, draft forces and power requirements of a plane blade were studied at several travel speeds. The blade was tested at a depth of 5 cm, rake angle of 90°and three travel speeds 1.8, 2.3 and 3.7 cm/s. The results obtained in this study showed that travel speed had considerable effects on draft force and power consumption. The results obtained by the developed soil bin was in accordance with the previous studies and it can be used as a reliable laboratory setup for further investigations on soil-engaging implements.
