Due to the hitch angle, as the steam tractor applies force it is essentially lifting the rear wheels of the superstock. The Farmall C is only rated at around 19 horsepower but it can certainly outwork your average 20hp lawn tractor. The PTO on your lawn tractor could never even get a hay baler to move let alone run it and pull a hay wagon behind it through a hilly field.
