I hate to be the devil advocate, and not trying to start drama. But What saw did you compare side by side with, Also could you explain about the john deer pushing so much more then the cat. Did they have the same kind of tracks? because the cat has more hp and is a heaver machine, I would think they would be very close, as the cat only weighs around one ton more, and only has a very small amount more power. The only reason I ask, when we give a opinion and compare something, lets make sure its unbiased. Because someone may use it, and there findings may differ.
