Abstract
A concrete saw (10) includes a cutting assembly having a high compression diesel motor (38) mounted on a carriage (40) in turn slideably mounted in a frame (22) in turn pivotally mounted to parallel rails (14) of a chassis (12) moveably supported on the concrete surface by wheels (18, 20). Concrete slurry hardened on two pairs of UHMW slides (30, 44) provided between the sliding surfaces of the carriage (40) and the frame (22) will break away and fall from the slides (30, 44) when the belt tension is adjusted. A guard (58) prevents entry of concrete slurry to the belt drive and includes a housing (66) having a U-shaped wall (68) which closely conforms to the bottom periphery of the sheave (36) of the belt drive. An operator platform including a seat (86), a footrest (88) and an armrest (90) mounted to a mount (82) is mounted by elastomer cushions (84) to a seat base (80) extending outward of the rails (14) of the chassis (12) so that the operator is located generally aligned with the saw blade (34) and is free of obstruction up to an extension (16) of the chassis (12).
