Electric concrete saw

A self-powered electric concrete saw comprising a frame having a front end, a rear end and a longitudinal length extending between the front and rear ends;

• a saw blade that is rotatably mounted relative to the frame and configured to be driven;
• at least one rear wheel and at least one front wheel mounted relative to the frame for facilitating movement of the saw;
• the at least one rear wheel and the at least one front wheel include at least one drive wheel;
• a drive system mounted relative to the frame and configured to drive the at least one drive wheel at a desired speed, the drive system being operably connected to the at least one drive wheel;
• the concrete saw further comprising a first electric motor and a second electric motor wherein the first and second electric motors are operable independent of one another;
• the first electric motor having a first motor power output and the second electric motor having a second motor power output wherein the first motor power output is greater than the second motor power output;
• the first electric motor mounted relative to the frame and being operably connected to the saw blade for driving the saw blade about a blade axis;
• the second electric motor mounted relative to the frame and being operable independent of the first electric motor;
• the second electric motor being selectively operably connected to the drive system and is operable independent of the rotation of the saw blade;
• the concrete saw having an internal power source to provide electrical power to the second electric motor to allow for powering the at least one drive wheel and movement of the concrete saw without connection to an external power source, further including a hydraulic system, the hydraulic system configured to at least power a lift assembly to adjust a blade cutting depth of the saw blade, the first electric motor being operably connected to the hydraulic system for driving the hydraulic system.
