Abstract
All all-terrain vehicle has a shiftable transmission that is coupled to a variable speed V-belt transmission. The variable speed V-belt transmission is joined to a crankshaft through a centrifugal clutching arrangement. The shiftable transmission enables an operator to go between low, high, neutral, reverse, and park. In the park position, the transmission is locked from substantial rotation such that the engaged wheels of the all-terrain vehicle are also locked from substantial rotation, whether or not the engine speed is sufficient to allow the centrifugal clutch to be engaged with the variable speed transmission.
