Recently I have been looking at some of the statistics for the old Ford Tractors. I can understand the meaning of horsepower and PTO HP, but don't know the meaning of belt or pulley horse power. (they always seem to be lower than the PTO HP) When I was about 5, my grandfather took me to a hay field where bailing was taking place with a Farmall M and a IH Type 15 hay press. This setup had a power take off (drum) on the side of the tractor and a large fly wheel on the bailer with a leather belt running between the two. I am guessing that this is not the type of belt HP they are talking about. Any explanation or help with its meaning or application would be appreciated.
