Centrifugal clutch mechanisms, and transmissions and lawnmowers having centrifugal clutch mechanisms are provided. A centrifugal clutch mechanism includes a clutch bell with a drive surface, and one or more centrifugal weights partially coupled to the first stage gear, wherein the one or more centrifugal weights are slidingly engaged with the first stage gear. Rotation of the first stage gear causes the one or more centrifugal weights to transition from a disengaged position in which the one or more centrifugal weights do not interface with drive surface to an engaged position in which the one or more centrifugal weights interface with the drive surface to transfer rotational energy from the first stage gear to the second stage gear. At least one of the one or more centrifugal weights comprises an axial projection extending towards the first stage gear, and the one or more centrifugal weights are slidable in the radial direction with respect to the first stage gear.
