Hugh MacKay said: (quoted from post at 03:17:23 05/06/09) Butch: I don't have the Nebraska tests with me however I do remember the Farmall 350 having the smallest gap between PTO and Drawbar horsepower of all tractors tested at Nebraska up to 1958. I also remember one or two of gas, diesel or LP gas made it over 40 hp on PTO. Drawbar on that same unit was 37-38, just about unheard of in 1958.
That probably hasn't changed much in the past 50 years, 350 could still be the leader, due to the fact that tractors since have power everything.
How's this? Some of the data does not make sense to me because why is there a difference in the percentage of HP loss from belt/pto/db from one fuel to another, unless there is a difference in the gear ratios for the different fuels?

Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day.
