I've read some nasty things on the early models of this ZTR - stamped decks, hydraulic motor failures, etc. What year did they have these issues fixed if they have them fixed now? I'm looking at a 2005 model with NO warranty and don't need/want to get a lemon with costly repairs. It's a bit suspicious to me why a LCO with a Huster and Exmark would pick this one to sell unless it has issues. Thanks.
