BRAKE SYSTEM AND LAWN MOWER IMPLEMENTING THE SAME
First Claim
1. A powered implement having an engine comprising:
- a rotating member rotated by the engine, the rotating member being electrically ground;
an ignition circuit that powers the engine, the ignition circuit operably coupled to a conductive member that renders the engine inoperative when electrically grounded;
a brake system comprising an actuator, the conductive member normally biased into a brake position in which the conductive member contacts the rotating member and is electrically grounded as a result of the contact with the rotating member; and
the actuator operably coupled to the conductive member so that actuation of the actuator moves the conductive member from the brake position to an operating position in which the conductive member is spaced-apart from the rotating member and is in an electrically non-grounded state.

Abstract
A brake system and powered implement, such as a lawn mower, incorporating the same. In one aspect the invention is a system for stopping an electrically grounded rotating member of an engine powered by an ignition circuit, the system comprising: a conductive member operably coupled to the ignition circuit that renders the engine inoperative when electrically grounded, the conductive member mounted adjacent the rotating member; and the conductive member normally biased into a brake position in which the conductive member contacts the rotating member and is electrically grounded as a result of the contact with the rotating member.
