A ground working implement including a frame having a plurality of rows of elements, each element holding a plurality of individual ground working tools extending downwardly. The implement comprises wheels which are used for transporting the ground working assembly which are pivotally connected to the frame and engage the ground midway between the forward and rear portions of the frame so that a tire track is never left in the ground when the implement is operating even if the wheels are touching the ground since ground working tools are positioned behind the tires as well as in front thereof. There is a tongue, adjustable in height, adaptable for connection to a tractor or other suitable motive power, and a selectively reciprocal power source, such as a hydraulic cylinder, for raising and lowering the ground working framework. Upon actuation of the cylinder for raising the frame, the forward end of the frame always rises first so as to permit accumulated trash to feather back through the ground working tools. As the machine rises, the wheels engage the ground and the ground working tool assembly may then be raised completely clear of the ground to a substantially level position for road transportation. Wings may be provided to increase the width of the implement and these may be folded into a vertical position for road transportation.
