Horsepower Question

Posted by Ben Shipley on March 07, 2007 at 06:44:32 from (12.4.254.254):

I am looking at a new tractor right now, and in my search, I have come across a question that i wanted to try and find the best answer to.

When we farm boys talk tractors, and talk about horsepower, we talk in PTO H.P., correct? In other words, when I say my litte Ford Jubilee has 31 HP, I am talking rated PTO H.P. I have been told that 75-85% of the PTO HP is a close estimation of drawbar H.P. Is this accurate? I have been told this by a few dealers, some use 75 some 85 %. Either way, without a dyno, it is still a guess.

Do you concur that we usually speak in PTO HP most of the time? Is my 75-85% number an accurate figure?

Thanks
