Pto adapter? Good quality one?
I had occasion to use such a number of times.
With any kind of shock loading on the shaft the adapter failed - - - - actually didn't show any stress fracturing was just like a hot knife going through butter (I'm also a machinist so have learned what stress fractures look like).
On a mower conditioner - - - might be a reasonable option. Would suggest watching for operating length though. Make sure the hoses from the pump don't ever get any kind of visual 'kink' in them - - - - that would be very not good for the pump!!
Possible that the companies have never produced such a pump (pto shaft for 1 3/4" 20 spline 1000 rpm) because that doesn't usually get used until a tractor is over the 160 hp range (used to anyway haven't been around enough newer tractors to know - - - grin!) so just not enough call for it = not enough profit = just ain't going to happen!
