Some guys are saying they're getting 100+ hp out of a JDG & some say even more. I certainly don't doubt that. But harnessing that much power out of the pto makes me not want to go there. I seen 70hp come out of my smaller G and my friend wanted to "lean" into it & I said no. After seeing the mess of shelled pto bevel gears in my other G, I have no way to know how this happened, but my guess is possibly hooked to a baler before it got sent to the salvage yard. Can you dyno off the pulley? How are these folks measuring 100+ hp out of a G when the engineers at Deere were putting out a 38hp pto tractor? The 2 bangers are certainly over-built everywhere else but the pto's are questionable with hp modifications.
