Just looked at the new Toro Z500 series 23/60 mower yesterday at my dealer. Looks impressive w/ changes from previous. I searched here and saw several guys commenting appearances instead of the actual performance of this machine. I will be demoing it next week after it dries out a bit here. Don't want to mess up the dealer's new machine since it just rained. Has anyone got experiences w/ this new deck and machine?? Please advise, looking seriously at this vs. Gravely 260Z for new purchase after season ends.
