True, but remember that roller is held on by bearings that mount to the deck. Every time that stripe kit is under load, so are the bearings. And thats exactly why those bearings fail. I replaced them once. They were Timkens and weren't cheap. I'm almost positive Exmark only warranties them for 90 days? Maybe a year? And I personally don't think the stripe is any better than running without it. Especially on the new Z's. Its the craziest design. You will have 5 different stripes as you mow.
