those are the coolest.. we have a mini pullers association here too .. they mix it up at events they have the different classes of tractors, then they let guys pull with quads/atv's too...LOL .. I did it a few years ago it was awesome I took a 2nd place with my Honda 4x4 quad in the 500cc class even though mine was a 450 since it wasn't stock I got put up a class.. I think I even have pics of it pulling the sled...
