I have a 2010 super Z Is there an update or aftermarket fix for the anti scalp wheels? Constantly tightening bolts broken plastic centers. Lock tight on threads, extra lock washers. Our old Cub cadet machines would have a double frame on each side of the anti scalp wheel. First replacement was 650 hours. Our Hustler has just 200 and I have changed out a few. Bolting the wheel to the side of the deck is just cheap.
