How much horsepower for a hay baler?

Answer:
It depends on the size of the baler. A 50 horsepower tractor is sufficient for a 90 pound bale size machine, while a big round bale machine needs closer to 100 hp. The full-size 4 foot by 4 foot by 8 foot 2,000 pound bales work most efficiently on a 150 to 200 hp tractor.
