I demoed a Z810A today for the first time. I thought it was very quick, however I still feel that it is cheap made compared to the 700 series. Just take a look at the frame for starters. (Where the engine sits, and bumper) Light guage steel. TOO much plastic. It rode like a log cart, no suspension seat standard. Love the improvements on the deck, front casters and forks though. I did find it to loose a little power when accelerating forward when mowing. I was told by the dealer that JD's temperary solution for this was to up the RPMs, but they expected new pumps by next year. What does everyone else think about these machines?
