Tom,<br> Toro doesn't manufacture exmark product, from my understanding, they bought exmark and actually use some of their technology for their rider line. As far as which one to buy, it all depends on what features one has that you like. Pistol grips or T-Bar design. Deck design features, do they both have the same engine? If you've never used the t-bar design, you might love it. Try both of them at the dealer's property. As far as longevity, I can't speak for exmark but I know that toro's hold up for quite a long time. As far as size, is there a reason for the 36"? <p>Mike
