Leroy I always check my numbers very close before I post them. The straight Farmall "H" was only 17-19 drawbar horse power or 21-24 belt. The later Farmall Super "H" was 29 PTO horse power. Still no power house.
As for a JD "B" they where an underpowered tractor as well but they did not have the high road gear that the Farmall "H" had. So they where not as bad on pulling on the road.
