Abstract—Use of soil tillage tool in agricultural field wants for soil failure. Behavior of soil failure: soil deformation and soil failure depend on soil properties and action force method. The subsoiler used to change the depth of soil from the surface to the ground breaking into a small block. The objective of this research was to determine soil flow pattern around the subsoiler type curved leg used computational fluid dynamics and to study soil fracture and soil movement of subsoiler type curved leg. Simulations carried out using ANSYS Fluent 14.0 commercial CFD software. The computational fluid dynamics used predict the soil flow through subsoiler type curved leg at subsoiler operating speed constant. For a subsoiler speed of 1.02 m s-1, with operating at 400 mm depth, rake angle of 30°. The results show, the soil failure is lateral deformation of subsoiler and soil movement on the surface of rake angle.
