i have a thing for watching videos of hit or miss engines they are just fun to watch run. machines from a different time where if you were not careful what you were doing it would rip you apart. anyways i found this neat video of these traction engines doing a record plow. it starts slow but wait till you see the size of the plow they are pulling :shock:
