  • Patent number: 5156218
    Abstract: A landscape edging machine detachably mounted to the frame of a commercial mower and connection to the power-takeoff shaft to provide rotational power through a drive mechanism to a rotatable cupped disc is disclosed wherein the edging machine is provided with a cupped disc having a serrated edge and being positionally angled with respect to the direction of travel of the machine to facilitate the digging of the soil out of a trench to form a line of demarcation between the grassed lawn area and the adjacent mulched plant bed. The rotatable disc is positioned proximate to the front wheels to permit the disc to easily track along with the mower around curved mulch bed lines. A gauge wheel forms a limit to the depth at which the disc will penetrate the ground. The attachment is pivotally moveable to an inoperative position above the ground.

  • Patent number: 5070946
    Abstract: A stone burying attachment for a finish grading landscape machine is disclosed wherein the attachment is optionally mounted to the frame of the machine to create a furrow immediately forwardly of the discharge side of the machine to permit a burying of stones and other unwanted debris collected by the landscape machine during operation thereof. The stone burying attachment is positionally adjustable between operative and inoperative positions to permit a selective engagement thereof at the discretion of the operator. The attachment includes a disc positioned angularly with respect to the direction of travel and also positionable at varying heights in the operative position for selectively varying the desired depth of the furrow being formed thereby. A breakaway feature protects the attachment if the disc engages an immovable object.
