A drive clutch assembly having a fixed sheave and a movable sheave rotatable with the drive shaft of an engine comprising a variable rate biasing or resistance system for urging a movable sheave toward a retracted position, the biasing system initially applies a first predetermined resistance to the movable sheave as it moves toward the fixed sheave and applies a second predetermined resistance to the movable sheave when the movable sheave reaches a predetermined axial position. |
