I think if you tried to use an A wheel on a Fordson you would turn it into a pretzel.When those things are set up correctly,at their very best they are mean.That wooden rim was big and beefy for a reason.Rotorwrench,the later N series tractors bear no resemblence to the Fordson model N.They were produced in Cork Ireland until the early 50's.I thought somebody was reproducing the wood rim,I just can't think of who.I have seen them with all steel steering wheels,but I don't know if they were originalLook on Yesterdays tractors,lots of guys in the know are on there,and most like to help.
