I am a die hard T-bar fan, I get great productivity out of a gear drive. But I've been looking at the Better Quick 36 w/ the 13hp Intek. I am attracted by the price, and all the good reviews I read here. However I have a few concerns. 1. 5 mph top speed (is that really accurate) My T-bars go 6.2mph 2. Is the 13hp Intek powerful enough? What about durability? Anyone got 2-3,000 hrs on one of these? 3. How intuitive are the controls? 4. I always run sulkies, how does the quick 36 handle a sulky? I'm really looking for someone who has owned/run both the 36" belt driven T-bar and the Quick 36". But any feedback from Quick 36 owners will be greatly appreciated. Thanks.
