Abstract
Apparatuses and methods are disclosed for controlling a variable speed transmission including an actuator, a cam follower, and a speed adjustment cam. The actuator is rotatable through a first phase and a subsequent second phase, and includes an actuator cam surface and a variator. The cam follower is movable in response to contact with the actuator cam surface during rotation through the first phase, for actuating a coupler of the transmission between a disengaged position and an engaged position. The variator is movable along the speed adjustment cam during rotation through the second phase for enabling adjustment of a torque transfer mechanism associated with the transmission. By this configuration, control over the coupling of the transmission to a torque input such as a motor and control over the speed of the transmission are both enabled through rotation of a single actuator, and thus can be implemented in a self-propelled machine such as a lawnmower using a single operator-manipulated control.
