I know that adapters exist to adapt a 1 3/8 implement drive-shaft to a smaller PTO on tractor. Does the opposite adapter exist to adapt a 1 1/8 implement drive-shaft to the large tractor shaft. I hope I explained it correctly.

Thanks
 
I have never seen an adaptor that would let you run a 1-1/8 PTO shaft on a 1-3/8 tractor. But just because I have never seen them does not mean there aren't any but I would think they would be hard to come by
 
Years ago Tractor Supply had them. I would suppose there are few old implements around with the 1 1/8 shaft around except possibly some of the Dearborn mowers that a fellow kept when he traded in an 8N for a jubilee
 
Right here on this site. I know it might not be what you want , but might work and you get an overide clutch also.

Thanks for the info. I plan to use it on an old backhoe from a Ford 9N mounted on a IH 359 Utility tractor.
 
NO! They make an adapter that is just a splined sleeve, slides over the 1-1/8" shaft, is 1/8" thk steel so is 1-3/8" diameter.

Dad had one on a 1939 H he bought before I was born, early 1950's, Bought a 1940 JD B with 1-1/8" pto in 1969, I bought the adapter for it at Blains Farm & Fleet.

Yes, they do make an adapter...1-1/8"x6 spline female to 1-3/8"x6 male.
without over running clutch if so desired.
