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. The transmission output shafts connect directly with the drive wheels, and clutch elements for use with the respective transmissions operably engage an input pulley to the transmission rather than an output pulley. The drive wheels are directly connected to the transmissions and the location of the clutching elements is within the periphery of the respective belts. The drive assembly is enclosed by the drive deck.
