A brush clearing apparatus for a bulldozer blade having a rake pivotally mounted on the blade for movement about an axis along the upper edge of the blade between an operational position in which the rake engages the bulldozing face of the blade and a retracted position above the blade, a clamp pivotally mounted on the blade for movement about the axis between a lowered position engaging the rake oppositely of the blade when the rake is in the operational position, teeth individual to the rake and to the clamp and extended in intermeshing relation adjacent to the lower edge of the blade when the clamp is in the lowered position; and a hydraulic ram mounted on the blade for moving the rake between its positions, the apparatus including an element for connecting the rake and the clamp so that raising the clamp to its upper position carries the rake into its retracted position and the blade is usable as if the apparatus were not mounted.
