Abstract

A combined engine flywheel and centrifugal clutch driver for a rotary lawn mower blade. Two heavy circular plates, as a quarter-inch steel plate, of large diameter, e.g., six inches, are riveted together against three peripherally spaced pairs of spacer slugs stamped from the same material, and against a central shouldered hub. This forms a rotor of sufficient rotational inertia when mounted on the depending shaft of a mower engine to provide the principal flywheel effect for an engine having a relatively lightweight magneto and fan rotor at its top end.
