Combined axle, bumper and safety guard for walk-behind mower

摘要

A walk-behind mower includes a pair of vertically adjustable front wheels supported on a unitary axle having an offset central portion, which serves as a bumper to protect the mower deck from striking foreign objects when the wheels are set for lower cutting heights and which serves as a safety guard to prevent anyone's feet or other objects from engaging the cutting blade when the wheels are set for higher cutting heights.
