Well, i dont know if this beats it, but one day while helping a friend feed cattle. the tracker didnt start. so we found a 5X7 sheet of plywood, layed on the ground, attached a rop, and buried it in about 25 bails of hay. hooked onto it with my 93 suby wagon and it took a while to get going being automatic, but after a couple running starts, we drug it about 5 miles in the mud. only comes out to be about 1250 pounds, but its a sled. transmission has never worked quite right since, has some hesitation.
