I have a 2008 60" Hustler Z with a 25hp Kawasaki engine that I purchased new from the dealer at the end of 2008. I purchased this mower to use exclusively on my own 5 acre residential lot. It is always garaged when not in use. Last week with only 230 hours on the unit, the muffler bracket broke, and the muffler just feel off. Replacement muffler is $200.00. I could not believe it! I run Toros for my commercial cutting business, and I have never had a muffler fall off before in my 12 years of operation. After closer inspection of the mounting design for the muffler, I can better understand why it broke. Only one welded bracket holding it on. My concern now is that the next muffler will break in another 200 hours. Is Hustler aware of any issues with this muffler bracket breaking so easily?
