Abstract

See full text

A utility machine including a frame, a prime mover supported by the frame, a pair of wheels rotatably coupled to the frame, a drive disk coupled to the prime mover to be driven by the prime mover, and a friction disk assembly. The friction disk assembly includes a friction disk in engagement with the drive disk for transmitting rotation of the drive disk to the pair of wheels, and a carrier disk coupled to the friction disk for rotation therewith. The utility machine also includes a shifter mechanism including a bearing disposed directly between the friction disk and the carrier disk. The shifter mechanism is operable to move the friction disk assembly with respect to the drive disk to selectively vary a drive speed of the pair of wheels.
