Abstract:
A concrete saw is disclosed having a rigid metal frame, a hydraulic drive system, a water-cooled hub, and an axially rotatable trigger assembly comprising a 12 volt switch. The saw may include a hydraulic pump operable to supply pressurized hydraulic fluid to the drive system. In some embodiments, the saw may includes a flow sharing valve fluidly coupled to the hydraulic drive system to distribute the pressurized hydraulic fluid from the a hydraulic pump in a portable power pack. A method of removing trip hazards with the saw is also disclosed.
