That 'steamer' was just playing with that Deere.

[Jagiven]

With the rubber tires on the steamer it did not even have full traction.

It's all about torque, traction and weight.

[mcfarmall]

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.

[Threebutchers]

In any tractor pull - as the dead weight slides up the sled - the loose dirt inhibits traction. The superstock was dead on traction to move a load of that weight before the match started
