Bull ****.

You should tell people that the very early traction engines were being
HP rated very differently and engines that were being sold as 10 HP one
year were being sold as 40 or 60 HP the next year and that was still
conservative.

I have seen a healthy 110 Case pull 14 14" bottoms (16 feet) one year
and fail to do it the next just because the ground was a little dryer
and packed a bit more, same engine, same engineer, same plow, same
ground. And a good 110 case will dyno at way more then the 110 HP that
Case sold them at, more like 170 to 180 HP.
