Has anyone had bearing problems with their Exmark Striping Kit Bearings. Both of mines are bad at 190 hrs. They are $75 apeice to replace. At this price I am going back to the Anti Scalp wheels for the winter and put the kit back on in the spring. Everyone needs to check theirs because mines almost wore off the tip on one end which would have trashed the whole kit. As a matter of fact its probally better to replace the kit than sink $150 in bearings. Or even better is it worth it?
