What outlawmower is saying is true. There is no comparison to pulling a mechanical sled. You can pull cars/trucks up the driveway all you want or mow with it as hard as you want. It does not compare to pulling a mechanical sled. I'll say this and shut up, it all depends on how far you want to take it. If you are just going to play with a stock class tractor then there are a lot of engines that will give you a good time. If you want to get past that then your choices become quite limited. I have seen B/S, Tech, Honda, Kawasaki, Kohler, Wisconsin all pull in stock classes and do good. Once they started opening up the governors then you will see a seperation of which ones will take it and which ones don't.
