I have an old, pull behind 2 bottom John Deere plow on steel. The only numbers I can find on it are 612 and 613. The 613 is the furthest plow back and it needs to have a wheel bolted on to it. There is part of the bracket on there already and the wheel has been broke clean off. I am hoping somebody out there will be able to tell me where I might be able to find a rear wheel and bracket for this plow. Any suggestions would be appreciated. Thank you.

It appears you have a JD model 52 plow which is a very desireable collector plow made from 1934 - . The actual rear steel wheel you need is Part Number 21558A. It isn't clear to me how much of the rest you have. I would advise you to get a Parts Catalog for the plow as it will help finding the correct parts immensly. I don't know what area you are from but there may be some local salvage yards that may still have some junk plows or look for fence row plows that may still have some goods parts on them.

Hope this helps.

Thank you, JDVan. I appreciate the feedback. Except for the missing wheel, the plow is complete. It had been sitting in a barn in West-Central Minnesota for quite some time. My dad bought it last spring for $50. If what you are telling me is accurate, which I have no reason to believe it isn't, this little find could be pretty exciting for dad. I will keep you posted. Thank you again for the information.
