ABSTRACT:
A side shifting mechanism for a transaxle includes a shift shaft which is rotatably mounted about an axis which is parallel to the axes of the drive axles. A portion of the shift shaft extends out the side of the transaxle to a location where it can be conveniently grasped by an operator. The shift shaft cooperates with a detent plate located within the transaxle. The detent plate is pivotably mounted on a pivot shaft. Rotation of the shift shaft causes pivoting movement of the detent plate about the pivot shaft. The detent plate is connected to an axially movable shifting collar. The relative position of the collar determines which of a plurality of gear ratios of the transaxle is selected for use. Thus, by rotating the shift shaft, the operator can select a desired gear ratio. In a first embodiment of the invention, the shift shaft and the detent plate are formed having cooperating bevel gear portions. In a second embodiment of the invention, the shift shaft carries a cam driver having a helical groove formed therein which cooperates with a cam formed on the detent plate.
