I was wondering about the PTO power out rating on tractors. To use my tractor as an example, it's rated at 39 hp gross and 37.4 hp net with a max pto at 30.5 hp. It makes sense that the sum of the power users can't exceed the source. And I would expect some mechanical losses in the drive train and then there is power steering pump and hydraulic pump losses with just circulating fluid.
My question is: if the tractor is parked with a PTO chipper attached, what is the maximum hp to expect at the rear pto? This is more a theoretical question seeing I doubt I could tell the difference in performance between 30 and 35 ish hp. But it seems reasonable to expect more than 30hp.
Thoughts?
ps my chipper isn't here yet but has a recommended 35-65 hp.
