6 spline pto shaft increaser

Regardless of who said it, the replies have been for possible reducer sources; not an increaser as was asked for.
SS55 was refereeing to a reducer from 1 3/4 to 1 3/8 the way I read it supplied by equipment dealer! Guess it's the way you look at it! Reducer/increaser are the same no matter what you call them!!
 
so, a 1 3/4" to 1 3/8" reducer?
Which size and type (male or female) is the 1-3/4 and which is 1-3/8 makes the difference.

In this case I would call it an increaser. The increaser would be 1-3/8 female on his Farmall M stepping up to 1-3/4 male for the tedder drive. He wants to use the Farmall M (1-3/8 male shaft) to run the tedder, which has a female 1-3/4, 6 spline yoke.

Reducer would be 1-3/4 female on the tractor shaft down to 1-3/8 male to drive the implement. That is what the JD GM or the Unimog (which Brendon-KS mentioned) would use to hook to a standard 1-3/8 6 spline PTO shaft.

Finally found a source:
Here's this, I don't know how good it is though...
Is this something like what you're looking for?

Yes, That looks like what he wants. 1-3/8, 6 spline female stepping up to 1-3/4 male, 6 spline.
 
He wants to increase his Farmall M 1-3/8" shaft up to 1-3/4".
I'm well aware of that. Just said the 1949 G came with a 1 3/4" PTO shaft and there is a reducer so the standard 1 3/8: equipment can be used with it. Some were saying it's a European thing but a JD G is definitely not European. The JD A's of the same age came with 1 3/8" PTO shaft. I'm not aware of anything made to increase the diameter.

It appears Powered by IH has found a source for the elusive increaser.

What is the brand of the tedder? I’m curious as to why the bigger than standard yoke is on the tedder. Somebody mentioned that 1 3/4-6 spline was a European thing, I’m wondering if it was a tedder meant for the European market?

From the implement side I guess it would be called a reducer, from the tractor side it is an increaser, LOL Either way the adapter connects a 6 spline 1 3/8 inch diameter Tractor PTO shaft to an implement with a 1 3/4 inch diameter 6 spline implement power shaft.

Could be worse, I'm a little surprised a European implement does does not use a metric shaft size or a different RPM..

At one time there was a European standard of 750 RPM.
