Well, I know that the Case is rated around 23HP at the bar. It looks like it uses about 40lbs of chips an hour running it around the yard in 7th gear (direct 3) I don’t have the tack hooked up so I can’t say what the rpm is.
I’m getting about 30 minutes on a hopper… It holds about 20 lbs of soft wood chips we’ve been using. I know now that the next 20 HP+ tractor will get a much larger capacity hopper… we live, we learn.
I may just let it run through a hopper at idle with no load to see how long it does that for in the morning…
I can say it pulls a bunch harder that the JD M we did this spring.
