Abstract
A large capacity, self-propelled walk-behind power tool, such as a lawn mower, employs gear-operated transmissions for independently driving each drive wheel. Control handles are connected to idler pulley levers and brake levers to control the movement of the driving wheels. A constant input rate to the control handles results in a variable output rate to the idler pulley levers and the brake levers.
