ABSTRACT:
A concrete saw is provided having an engine aligned along a longitudinal axis of the saw frame to minimize the width of the saw and provide a more balanced system. A clutch assembly is attached to a forward end of the engine to disengage the saw blade without stopping the engine. A right angle gear box is provided proximate the driven side of the clutch assembly to transfer driving rotational forces from the engine to a transversely aligned driven shaft. The driven shaft includes drive pulleys mounted upon opposite ends thereof, which are aligned with driven pulleys mounted upon opposite ends of a blade support shaft and linked to one another via multiple belts. This alignment evenly balances the load transfer while facilitating the use of vibration isolators between the engine, gear box and frame. A hydraulically controlled depth stop mechanism is included for setting a maximum cut depth. The engine speed is controlled by an electronic governor. A multi-speed transmission is included to afford high and low ranges for the saw. A single control lever is provided to shift between high and low ranges, between forward and reverse directions, and to raise and lower the saw.
