Abstract
A self-propelled power implement having a friction drive system to transmit rotation from the engine to the wheels. The friction drive system includes an output disc and a friction disc. The output disc rotates in response to rotation from the engine's output shaft. The friction disc is coupled to the implement's wheels, and contacts the output disc and rotates in response to rotation of the output disc. The location on the output disc that the friction disc contacts determines the rotation speed of the friction disc. A flexible member is interconnected to the friction disc and a controller, and movement of the controller causes the flexible member to actuate the friction disc radially in relation to the output disc. The flexible member adjusts the location on the output disc that the friction disc contacts, and thereby adjusts the rotation speed of the friction disc and the wheels.
