Using the hydraulically driven saw attached to a compact track loader, [Ed Jones] and the FeeCorp crew were able to easily cut through the concrete and remove manhole casings. "This saw is great for raising and repairing casings," Jones says. "One man can use this saw to do the job completely. The saw is easy to use and has a smooth operation. Once it's locked onto the casing, the machine does not tear or bounce the equipment around. It does all the work itself.

       manhole casing, or lid, and
