| Abstract | A Simple First Order Linear Differential Equation has been developed to predict the dynamic behaviour of the soil engaging implements in the longitudinal-vertical plane when mounted on a three point linkage. Virtual Hitch Length has been found to be the single major factor which causes the implement to follow a specific exponential path. The governing equation is Y + V(y - ye )/t.= 0 where y = initial depth of the implement ye = equilibrium working depth of the implement yํ = penetration velocity of the implement V = forward velocity of the tractor t = horizontal distance between the implement and the virtual hitch point. To test the validity of this equation many runs were carried out at different depths while varying the virtual hitch length by changing the hitch configurations. The results showed generally good agreement between experiment and theory, the differences being due more probably to limitations of the experimental apparatus then to limitations of the theory. |
