A vehicle-mounted tool, such as a blade, may be disposed in an upright position for dozing or other pushing functions when the vehicle moves forwardly and then flipped over into an inverted position for back-dragging or the like when the vehicle moves in reverse. Flipping of the blade is accomplished using a cylinder operated from the seat of the vehicle. The blade is mounted on a swivel head that is controlled by a pair of oppositely actuating swivel cylinders from the operator's seat so that whether the blade is upright or inverted, it may be swivelled left or right into any number of obliquely disposed positions.
