The shape optimization procedure using FEM was carried out for the specific purpose of analysis of a tractor chassis frame. To examine any possibility for mass reduction, its applicability was discussed in terms of geometry deformation and stress distribution comparing with the optimized shape and the prototype. Minimization of the mass as an objective function is executed under multiple constrained conditions of nodal displacements and stresses. The optimization progress executions were succeeded in converging into single optimum solution. Although mass reduction and stress alleviation were attained by 40% and 26 to 34% respectively, the geometry of the shape is so complicated for fabrication that the refinement of the geometry is necessary
