Abstract
A guide shoe attachment for a clearing saw having a shaft defining a centerline, a transmission connected to the shaft including a hub rotatable in a predetermined blade rotation direction about an axis of rotation angled with respect to the centerline, and a circular blade connected to the hub. The guide shoe attachment has an elongate guide member extending radially outward from the hub generally in the direction of the centerline, parallel to and above the blade, providing a guide edge for guiding the saw. It includes a top plate forming a semicircular guard around for blade with fittings for connecting the attachment to the transmission at a position above the blade and forwardly of the transmission. The guide member includes a skid aligned with the guide edge. The guide edge is offset from a centerline of the clearing saw in the direction of blade rotation so that a tree contacting the guide edge is sawn within a kickback zone at the front of the clearing saw.
