The Bigfoot Early Entry Green Concrete saws are available in either 22 hp or 13.5 hp versions. Using TankTrack belts running alongside the blade, Bigfoot saws avoid leaving unsightly scratches like those left by primitive skid plates and they help to pull the saw and maintain a straight line. Using advanced hydraulics for all major operations ensures the least amount of required maintenance. Cardinal Saws and Blades. 888-503-3353.
