ABSTRACT:
A vehicle drive system particularly suited for snow blowers includes a main sprocket rotatably carrying a first and second pawl. Each pawl drivably engages a respective sprocket. The first sprocket is fixably mounted to a first axle means such that rotation of the main sprocket causes the first pawl to drivably engage the first sprocket to rotate the first axle means. A second sprocket is fixably engaged to a second axle means such that rotation of said main sprocket causes a second pawl to drivably engage the second sprocket to cause rotation of the second axle means. Friction means supplies sufficient drag to the pawl such that rotation of main sprocket causes each of the pawls to assume an engaging orientation with their respective sprockets. Each of the pawls can be selectively disengaged from a drive orientation by manually advancing the respective axle means, i.e., when an operator maneuvers the vehicle for turning.
