CHALLENGES IN THE 3D MODELING OF A FIELD CULTIVATOR FOR SOIL PREPARATION

Abstract

Prior to planting, the soil must be prepared usually by machines called cultivators. Older field cultivators are suitable for modification for row cropping. The crops and the tractor power available will determine specific needs. Factors to consider include row spacing and row spacing flexibility, whether you need a towed or tractor mounted unit, frame size and layout, ease of levelling, ease of moving, removing, and replacing shanks, overall machine condition, and the robustness of the shanks. The paper describes the struggle concerning the 3D modelling of such a field cultivator with special features.
