I am in the market for a used mower. Not sure if I will be mowing in 2 years so, not wanting to commit to a new mower payment. I have found a 2006 Kubota ZD25 for $5500 with 1200 hours on it. How many hours can I expect out of this motor. Diesel motor seems to run great. I didn't get to cut with it due to rain. I might can get the guy down to $5000 if I try. I will demo it before I buy it. Any known issues with the year or model would be appreciated?
