Abstract
A walk-behind, self-propelled lawn mower having a variable speed drive transmission responsive to operator applied forces. The drive transmission is mounted on a frame and comprises gearing operatively connected to an engine and a drive shaft for transmitting forces from the engine to the shaft. A clutching structure including a frictional coupling is coactable with an element of the gearing selectively to provide force transmission to the drive shaft. An actuator structure is controllably connected to the clutching structure and responsive to operator applied forces for controlling the speed at which the lawn mower traverses along a ground surface and to vary the speed proportionally to operator applied forces. The lawn mower also includes a handle pivotally connected to the frame and operatively connected to the actuator structure. The handle is adapted to pivot in response to the operator applied forces.
