Throwing of Clods by Blades of Reverse-Rotational Rotary Tiller (Part 2)

Rigid Body Kinetics Model for Backward Throwing of Tilled Clod

Abstract

A limit of the predictability of the particle kinetics model is identified for a large clayey clod backward throwing of tilled clods. The model based on the particle kinetics is, however, unable to predict the clay soil tilling performance. A new model that is based on the rigid body kinetics mechanism is proposed to explain the tilled clods backward throwing. Using this new model, more exact prediction is possible for the tilled clods backward throwing loci on the clay soil formed the long sliced clods. The model has an advantage of including the influences of moment of inertia of clod and its rotation action.
