I have a 2006 Mini Z 19/42 (don't have the serial # handy), but can get it if necessary. The mower has approx. 350hrs on it and I purchased it new. Yesterday while mowing the right rear rim cracked around all 4 lug nuts. I have read a couple of older post indicating there may have been a bad batch of wheels around this time and they were/are replaced at no cost to the consumer. Does this replacement only apply to mowers within the warranty period of the mower or will Hustler still replace this rim regardless of its age because there was/is a known defect with these wheels. Thanks for the help.
