abstract="This paper examines conditions under which the overturning stability and directional control of two-wheeled drive tractors with mounted or towed implements are lost on sloping ground. Theoretical methods are derived for predicting these conditions. Confirmation of the predictions by experiments on full size machines and models was obtained. The theoretical methods are used to examine the suitability of some frequently used tractor/implement combinations for use on sloping ground. It is concluded that loss of wheel/ground adhesion, rather than the likelihood of overturning, limits the slope on which most combinations can safely operate.<p /><p>Language: en</p>",
