Haven't used any Toro's before. How much would a 2009 Z400 with 100 hours be worth? This is a 52 inch cut with a 21 Kawasaki. Good mower? I haven't read any real negatives. I contacted a local dealer today and they said the 400 series has been discontinued. He had one new one left and would sell for $7600. Thanks for any input or advice on the used machine.
