Thanks for the interest. It is a 2004 Model W4815 ETS. Only reason we are selling is because we have upgraded to a zero turn rider. The Kawasaki 15HP motor runs awesome. The mower runs/cuts great as well. The only thing that I can say is "flawed" about the mower is that it doesn't go into the highest gear at gear 5. This is not as issue because the only time you would ever possibly want to go this fast would be if walking between properties, otherwise, gear 5 is extremely way to fast to cut and keep up with. Do you have any other questions I can help you with?
