The suspension for the tractor manufactured for trial was constituted by using parallel link type for front wheels and trailing arm type for rear wheels, therefore, for the basic design, the characteristics of the parallel links and the ground load of the tractor manufactured for trial were examined.
First, the equations for the equilibrium of forces acting on the links were derived, and the force acting on each link was determined. Then, by taking this equation of equilibrium and the ratio of side forces, the equation for determining the ground load when the tractor stands still in the direction of contour line was derived, and the equation was confirmed with a model test, at the same time, the mechanical characteristics were clarified.
