I would like to see the 4 spoke wheel in question as I can not recall ever seeing an IH built cub cadet with a 4 spoke steering wheel. They were all variations of a 3 spoke wheel that I have ever seen.
I agree that there were no 3 spoke wheels pre 81 but they used them on quite a few after that.
Do a Yahoo search for "cub cadet steering wheel", click "images", 3rd row down, second from the left. Apparently they were used on 1110,1225,1320,1420,etc. There was another 4 spoke wheel used on 1440,1641,1535,1541,1863 etc. But flatter and with wider split spokes.
Luckily for me the original 149 wheel has grown on me so I'm just gonna keep it on there.
