I have found a 1999 60" dixie chopper flatlander 191 hours with a 25 hp Kohler and the micron filtration system. The guy wants $6000 for it and it was used non-commercially. Is this a decent price and is there anything I should look for or be aware of before purchasing this mower. It has new blades and has recently been serviced out . I have never owned a ZTR, but I have heard that these are great mowers. Thank you for any advice on this....L.T.
