Abstract: What is disclosed is a lifting bale that has at least two side supports, at least two cross support, and at least one center support and ideally configured to fit over the motor of a concrete saw, to provide handles for lifting the saw, and to provide an attachment point for a lifting mechanism to attach to the lifting bale and to lift the concrete saw, or other object the lifting bale is attached to, upward from the single point while maintaining the concrete saw or other object in a generally level position.

Abstract: The present disclosure is a vibration dampening assembly for a walk behind concrete saw having a frame and deck assembly, an engine mounted to the top of the deck, a pair of rear wheels interconnected by a nonrotating solid axle which spans the width of the deck and is attached to the frame, and a handlebar post having a lower portion, a pair of outer, generally rectangular, damper blocks, having a front portion and a rear portion, attached to the underside of the deck in parallel juxtaposed relationship; front and rear cross members for interconnecting the front and rear portions of the outer damper blocks to form a generally rectangular grid frame; a pair of inner, generally rectangular, damper blocks attached to the lower portion of the handlebar post in a position where there is no metal to metal contact between the lower portion of the handlebar post and the deck; and means for attaching the inner damper blocks to the front and rear cross members.

Abstract: A clutchless belt drive system for pavement saw. The saw having an engine mounted to a frame via a pivot mount. The engine drives a first pulley, which is fixed relative to the engine. The first pulley drives a belt, which in turn drives a second pulley. The second pulley drives a saw blade. An actuator connected to the frame and to the engine so that the actuator extension rotates the engine in a first direction about the pivot mount, driving the first pulley against the belt and tautening the belt about the first pulley and the second pulley, and so that actuator retraction rotates the engine in a second direction counter to the first direction, releasing the first pulley from the belt and relaxing belt tension. A shroud encircles the belt in a plane perpendicular to the line defined by the center of the first pulley and the center of the second pulley. The shroud is positioned so that when the belt tension is relaxed, the belt contacts the shroud and the resulting friction decelerates the belt.
