I edited this post after realizing the thread that I had responded to. I only saw the first few posts. I would have prefered to let this thread die. Below is my original post.

If you want to compare pulling power, the pulling schedule for the Mid Michigan Mini Tractor Pulling Association is at http://Steve.Bishop.net/mmmtpa

The Polaris quads rule the ATV pulls. They are still spinning their tires when they stop. The Hondas and other machines with auto clutches are not spinning their tires, but the engine is still revving.

Pretty much everything out pulled a 6x6 that was there one day. It had a Kohler command 20HP motor.
