Abstract
A vibratory ground roller composed of a main frame carrying a plurality of rolling drums one in front of the other and a steering frame attached to the back of the main frame has the steering frame connected to the main frame by a plurality of links forming a pivoted link system each link of which is pivotally connected at its front end to the main frame and its back end to the steering frame and the system is so arranged that when the main frame pitches, the resulting horizontal movements of the pivots of the rear ends of the links to the steering frame are at least substantially equal to each other.
