摘要: A cordless mower, including a start-up key that must be removed to charge battery. The inserted operate the motor, and can moved different position or interrupt motor. mower cannot operated when switch is not actuated. Some embodiments include lockout relay disables charging of battery on exceeds predetermined threshold.
