The other day one of our fairway mowers went down and I'm afraid it might be for good. It's 8 years old and and has over 5,000 hours on it. We really haven't had the chance to tear it apart yet to do a proper evaluation, but hopefully we can get to that next week. The biggest problem is that our other unit, the one that is still working, is blowing out black smoke and is even older with more hours on it then the one that went down. We'll just have to keep our fingers crossed.
