An electric walk behind greens mower includes an electric reel motor rotating a cutting reel; an electric traction motor rotating at least one traction drive roller; and an electronic control unit commanding the electric traction motor and the electric reel motor to rotate at reduced speeds during a turn if an electronic signal indicates a deviation from a normal walk speed. The electronic control unit also may determine if the actual speed of the electric traction motor is substantially less than the speed specified by a speed lever, and then command the electric reel motor and the electric traction motor to rotate at a lower speed than specified by the speed lever. The electric walk behind greens mower also may include a battery management system that activates a low voltage power supply if a key switch is turned from the off position to the run position, and that provides a start signal to an electronic control unit if the key switch is momentarily turned from the run position to the start position whereby the electronic control unit activates a high voltage power supply to the electric reel motor and the electric traction motor. 111-.
