A plurality of wheels support the frame for movement in a forward or rearward direction. The frame includes a pair of floating elements pivotally mounted thereon. Each floating element supports a blade thereon such that the blades are laterally spaced apart on the frame and extend transversely to the forward direction. The blades are free to pivot upward and downward with the respective floating elements about respective longitudinal axes extending parallel to the forward direction. A pair of adjustable mounts mount the respective blades on the floating elements such that a vertical and horizontal spacing of each blade relative to the frame is adjustable. The adjustable mounts each include a shaft having an upright axis for pivotal movement of the blades about the respective upright axes such that an angle between the blades and the forward direction is adjustable.
