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.
