An electric concrete saw used for modifying a material, the 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, a rear wheel and a front wheel mounted relative to the frame for facilitating movement of the saw, a drive system mounted relative to the frame and configured to drive at least one drive wheel at a desired speed, the drive system operably connected to the at least one drive wheel, a first electric motor mounted relative to the frame and configured to be operably connectable to an associate first power supply for receiving power therefrom, the first electric motor having a first rotational output operably connected to the saw blade for driving the saw blade and selectively operably connected to the drive system, a second electric motor mounted relative to the frame having a second rotational output, the second electric motor only powers the drive system wherein the second rotational output is selectively operably connected to the drive system and does not power the rotation of the saw blade, the second motor is operably connectable to a second power supply, a de-coupler adapted to selectively decouple at least one of the first electric motor and the second electric motor from the drive system, a controller configured to control operation of the first electric motor and the second electric motor, wherein the concrete saw is operable in a first mode where the at least one drive wheel is driven by the first electric motor and the saw blade is operable,, and wherein the concrete saw is operable in a second mode where the at least one drive wheel is driven by the second electric motor for movement of the electric concrete saw only. 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, a rear wheel and a front wheel mounted relative to the frame for facilitating movement of the saw, a drive system mounted relative to the frame and configured to drive at least one drive wheel at a desired speed, the drive system operably connected to the at least one drive wheel, a first electric motor mounted relative to the frame and configured to be operably connectable to an associate first power supply for receiving power therefrom, the first electric motor having a first rotational output operably connected to the saw blade for driving the saw blade and selectively operably connected to the drive system, a second electric motor mounted relative to the frame having a second rotational output, the second electric motor only powers the drive system wherein the second rotational output is selectively operably connected to the drive system and does not power the rotation of the saw blade, the second motor is operably connectable to a second power supply, a de-coupler adapted to selectively decouple at least one of the first electric motor and the second electric motor from the drive system, a controller configured to control operation of the first electric motor and the second electric motor, wherein the concrete saw is operable in a first mode where the at least one drive wheel is driven by the first electric motor and the saw blade is operable,, and wherein the concrete saw is operable in a second mode where the at least one drive wheel is driven by the second electric motor for movement of the electric concrete saw only.
