Abstract
A battery powered lawn mower includes a cutting deck 2; an electric motor 6 mounted on the deck 2; a battery 8 mounted on the deck which is in electrical connection with the motor 6; and a switch 12 mounted on the deck 2. The switch is disposed closely adjacent both the battery 8 and the motor 6 and is between the battery and motor in the electrical circuit. The switch is linked by a cable to a lever mounted on the mower handle which controls the switch so as to be in one of two positions. In the first position the switch links the motor and battery so as operate the motor. In the second position, the switch links the two terminals of the motor so as to create regenerative braking within the motor.
