ABSTRACT:
Shift mechanism is provided for a gearbox, such as a transmission or transaxle, of a small vehicle. The shift mechanism has three functions. It shifts or changes the gear-engaged condition of the gearbox. It moves a clutch between engaged and disengaged positions. It also actuates a brake of the vehicle to move it between a braking position and a release position. Further, the shift mechanism achieves all three of these functions through a single shift lever which is manipulated by an operator. The shift mechanism also causes the brake to be moved to its braking position at any time the gearbox is moved between a forward speed condition and a reverse speed condition, to avoid extreme, lurching movements of the vehicle.
