Abstract
A walk-behind self-propelled apparatus having a mobile structure and a handle assembly coupled to the mobile structure. The handle assembly includes a pair of grip portions. A ground engaging traction member is rotatably coupled to the mobile structure and imparts traction movement to the mobile structure for movement on the ground. A power source outputs drive power and a drive system, coupled between the power source and the ground engaging traction member, selectively transmits the drive power to the ground engaging traction member. A speed control actuation system coupled to the drive system includes a control member pivotable about an axis. An electronic member senses a control member rotation and relays an electronic signal to a controller which generates a linear speed control signal to the drive system.
