Bentleg furrow openers can significantly reduce soil disturbance and
reaction forces relative to conventional narrow point openers used in no-tillage farming.
The effect of bentleg opener geometry on soil disturbance and reaction forces in a cohesive
soil was assessed in a virtual soil bin using the discrete element method.Furrow size was
found to be more dependent on shank lateral offset and side leg bend angle than side leg
forward angle. Though side leg forward angles >90° reduce particle displacement and will
work better in fields with stones and roots, they also considerably increase draught and
penetration resistance. A low rake angled foot minimises soil reaction forces and drives
soil loosening. Reducing foot height and interaction of the vertical shank with soil particles
minimises surface soil displacement. These results have expanded the understanding of
bentleg opener mechanics and are in close agreement with those reported for sandy soils.
Therefore, similar criteria can be followed to optimise bentleg opener design for different
soil types.
