  • Variable speed leaf blower
    Patent number: 6834413
    Abstract: A portable leaf blower that includes a housing having an inlet and an outlet and an impeller adapted to generate an airflow from the inlet to the outlet. An electric motor rotatably drives the impeller. The leaf blower includes a power control circuit for substantially continuously varying the speed of the electric motor. A thumb wheel mounted in the handle of the leaf blower is used to control the amount of power delivered to the electric motor.
