Further evaluation and modification were done on the new concepts plow (frontal plow), a plow which inverts the soil furrow without lateral displacement . First, kinematics of soil cutting section was analyzed and an experiment was conducted to report draft and power requirement. Second, function of main moldboards was examined and modification was made. As a result of the modification , force applied to the moldboard was reduced, but the furrow inversion became less stable.
