✦ Synopsis

A three dimensional computer graphics technique has been applied to describe a mouldboard plough surface. An existing two dimensional soil-tool interaction model for an inclined plane has been modified for a three dimensional case. An interactive computer program has been developed to solve for the draught, lateral, and vertical forces using the 3D soil-tool interaction model for a mouldboard plough as defined by the 3D computer graphics technique. The program allows the user to change plough surface, soil properties, and operating conditions. The plough forces as predicted by the computer program were compared to the experimental results available in the literature. It was found that the draught force could be predicted using this method. The model was unable to predict the lateral and the vertical soil reactions.
