Abstract: An apparatus for removing material from the ground is disclosed, with a path-clearing blade, a vehicle mounting, a body supporting the blade, and a jointed connection between the vehicle mounting and the body permitting the axis of the blade and body to rotate within a plane parallel to the ground. The jointed connection has first and second pivot arm each pivotally connected about a proximal axis of rotation relative to the vehicle mounting and pivotally connected about a distal axis of rotation relative to the body. As the body's axis rotates in the clockwise sense, the first and second arms each pivot counterclockwise about their respective proximal axes of rotation, and vice versa. The arms are preferably disposed above the body and the distal axes of rotation are mounted forwardly of the rear edge of a horizontal rotating brush mounted in the body behind the blade.
