Chisel enables tillage without needing a plough for the harvest. Due to its leg structure, the plough breaks the lower layer and this machine is a suspensory machine for low clod soil which cannot be ploughed during dry summer months.
High working depth tillage is possible with the chisel. Thus, the soil is ventilated, the rainwater on the surface is prevented to be absorbed by the soil for the soil to protect its moisture and the hard layer is broken for the plant roots to easily grow to the bottom.
