Maximum pull certainly IS maximum DBHP, that was the subject.

The written test always gives the weight, look it up. The mfg. rep. is
there to be sure his tractor is tested fairly and looks good. It took
weight to add 25% more DBHP to the Test G . .

Too wrong and ridiculous for comment . . you "haven't a clue" as to drawbar
horsepower.

Too wrong and ridiculous for comment, you have NO concept of drawbar HP.,
your little car may have 100 FLYWHEEL HP . . . but you don't know the
difference . .

Wrong again, . . . you are amazing!

"The University of Nebraska Tractor Test Laboratory is the officially
designated tractor testing station for the United States and tests tractors
according to the codes of the Organization for Economic Co-operation and
Development (OECD). Twenty-eight countries participate in the tractor test
codes, with active tractor test stations in approximately 25 of those
countries. The OECD codes require that tractors be tested in the country of
manufacture. Reciprocity agreements with the codes require that once an OECD
test report is officially approved, it must be accepted by all participating
countries."
I'm out of here, no more response please, I'll delete it for obvious
reasons.
