I bought a new Ferris 1500 z a couple of months ago. I have tried new blades, double blades, mulch blades and no matter what we try it has not cut very good. We like everything about this z except the quality of cut. I complained to my dealer about ,but he had nothing to say so now what do I do. It has 35 hours on it ,and we ordered a mulch kit to see if that helps. Basically it misses grass, it leaves a ton of dead grass after it cuts ,and yes we have tries double cutting. I have yards that last year with my "consumer" z Simplicity were taking 25 minutes and looked great ,today it took us 60 minutes and still didn't look very good. I need some advice, I am ready to throw in the towel on this mower ,but I don't want to make a rash decision. I would like to hear from other Ferris 1500 owners to see if they are experienceing the same problems.
