I currently run a variable speed bobcat 36". I have a bad back and was looking to upgrade to a hydro 36" to make my life a little easier. My business is small and so is my budget. Although with getting hydro I might be able to pick up a few more lawns. Is is it possible to get a decent used hydro for around $2,000. Currently looking at and Exmark Viking 36" for $3,000 which has about 3,500 hours on it... Is that a reasonable price and how many is too many hours? Any advice would help. Thanks.
