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.
