I am looking to trade my '01 Z149 20hp Kohler w/ 52" deck and DFS for a Z560 30hp Kohler w/60" Turbo Force deck. Dealer quoted me $8800 cash for the Z560. I'm not sure what my mower is worth, it has roughly 900 hours on it. Still runs well and the bagger is excellent. We mainly use the bagger in the fall for leaves. I'm thinking that we could go back to mulching the leaves with gator blades and the adjustable baffle on the turbo force deck and be faster. Do you guys think that is a fair price on the Z560? Not sure if I should trade my current mower or sell it out right?
