Abstract
A drive assembly for a walk-behind, powered device operably couples an engine of the powered device to a mobility assembly to provide mobility of the powered device responsive at least in part to operation of the engine. The drive assembly includes a transmission shaft and a short turning assembly. The transmission shaft selectively receives drive power operably coupled from the engine to drive a first drivable component and a second drivable component of the mobility assembly. The first and second drivable components are disposed substantially at opposite sides of the powered device. The short turning assembly is configured to cause both disengagement of drive power and activation of braking to the first drivable component while drive power is provided to the second drivable component.
