Introduction: K'NEX Unlimited Modified Class Pulling Tractor

Picture of K'NEX Unlimited Modified Class Pulling Tractor

Open class, powered by an ice cream maker motor. Something in the neighborhood of 220:1 gear reduction. I ended up having to use safety wire to hold most of the gear locks on. It likes to throw them ten feet otherwise. Video here: http://www.youtube.com/watch?v=8XJflwkvfeI
