I visited a Toro/Exmark/Stihl dealership yesterday. This dealership is a bit out of the way, yet seems to have the best reputation within 200 miles or more. The owner recommended the Exmark stand-on aerator vs the Toro. I also noticed a recent thread regarding 30 inch stand-on aerators has been "closed". Don't know why?? Cuz we plan to purchase one or two of these units within weeks. PM me if you want to know the "owner of this dealership" I spoke with. Which stand-on aerator is best? Are there differences between Toro & Exmark?
