Description: A series ofexperiments were conducted in the soil bin for investigation ofthe assumption that the advance ofthe soil failure zone and the energy requirement for manipulation of the soil in tillage operations will reduce if operating speed is greater than a critical speed. Several flexible sensors (piezo films) were embedded into soil in the direction oftool travel to measure soil deformation during tillage operations. The soil failure zone in front of the tool was determined by the measurement of the distance from the tool to the point at which the soil began to deform. The preliminary test results indicated that the operating speed effect on the advancing speed of soil failure at different soil moistures, soil compactions, and tool shapes could be evaluated by this technique. As a result, the critical speed can be calculated for the given soil conditions and tool shapes.
