My Land Pride tiller has the small end on it, leaving the big end for the tractor.
Slip clutches go on the implement end, and all mine have the female segments of both shaft and cover on the tractor end. And one of the uses for the chains that come with the outer covers is to hang/suspend the shaft from the 3-point yoke when the implement is no longer attached to the tractor. When this practice is followed, the (disconnected) tractor end of the shaft remains higher than the implement end.All good answers in theory. But....on PTO shafts where you don't have a choice (like with a slip clutch or bolt-on yolk to the implement) the smaller diameter tube is on the tractor's side IIRC. Maybe someone can correct me if I'm wrong - but it is a good gauge for the correct answer.
Rain or water on the PTO shaft is more likely to happen when the shaft is OFF the tractor and just sitting there dangling down. Thus, the narrow diameter should go on the tractor's side
Confused enough? I think if both ends have identical spline it doesn't matter how you connect it. It will work either way. More important is to keep the joint in "phase".

I'm having a hard time coming up with a reason that it shouldn't work either way.
