Abstract
A walk-behind, self-propelled lawn mower having a variable speed drive transmission responsive to operator-applied forces. The transmission includes an input gear operatively connected to the engine for constant rotation during operation, an intermediate gear meshed with the input gear, and a driving bevel gear meshed with a drive shaft bevel gear. A face of the driving bevel gear is biased away from a face of the intermediate gear. A clutching surface is interposed between the gear faces for coupling the intermediate gear and the driving bevel gear in driving engagement. An actuator lever is controllably connected to the intermediate gear and can be adjusted to vary the sensitivity of the drive transmission to operator-applied forces.
