Abstract
A riding saw apparatus (20) has hydrostatic and hydraulic controls (26, 30, 31, 32) which are movable to various positions for different sawing operations. In addition, saw blades (72) mounted on a cutting assembly (24, 25) are movable to different positions at different angles for performing a number of sawing operations including sawing joints, making angled cuts, and following random cracks or curves. In addition, a timing mechanism (82) may be added so that the saw (20) may utilized for sawing recesses (110) in the pavement. The timing - mechanism (82) uses a cam (84) with a cam follower (86) controlling the depth of the cut of the blades (72). The saw also utilizes a mounting bracket (80) for mounting front wheels (38) or the cutting assemblies (24, 25) in different positions for the various sawing operations.
