Abstract

An apparatus for propelling a wheeled vehicle which has a hand-manipulated lever that is connected to a clutch assembly. The clutch assembly has a drum that is rotatably connected to the vehicle and brake bands that are pivotably connected to the lower end of the lever. An actuator rod connected to the lever causes inward movement of the bands to engage the clutch. Once engaged the vehicle can be propelled in which ever direction the lever is being rotated.
