I like your thinking.

I can find 10 spline to 6 spline shaft couplers on the web all over the place.
Will you send me a link to one? I've looked and haven't found one where the 10 spline female end is 1.5" diameter.

so you are saying to up size this to 1.5?

Missing the steel gauge wheel

Thank you.
Yes I think it is the E50 because it has a 50" till width and over all width of 62". I wish the factory tag was still on it. Yes the gauge wheel is missing.

I saw a Model E, but the 3PT hookup was slightly different from what he had. Yet the remainder seemed similar.

Yes, please do look it up. I'm curious too. (y)

I just found a serial number stamped on the staytube, 6375186. In one manual it had series numbers compared to serial numbers. So given that serial number I think it is a series IV. Correct me if I'm mistaken. See picture.
Again thanks for all the help.

SOLUTION. I ended up having an adapter machined to go to a typical 6 spline shaft. Then added a shear pin.
