ABSTRACT:
A concrete cutting saw (10) includes a wheeled main frame (12) on which a blade support frame (14) is mounted for movement between upper idle and lower cutting positions. Low and high speed blade arbors (16, 18) are rotatably mounted on the blade support frame (14) and each has an arbor head (24, 26) for selectively and alternately mounting either a low or high speed rotary cutting blade without any blade interference with the other arbor head. A drive mechanism (32) rotatively drives the low and high speed blade arbors (16, 18) at low and high speeds such that concrete cutting can be performed at the best rotational speed for the particular job cutting to be performed.
