John Deere B missing serial number tag

My Dad (retired) has just purchased a John Deere B for a restore project. Something to occupy his time and keep him busy. The tractor is missing the serial tag. Is there any way to determine the serial number of his tractor since the tag is gone?
 
The short answer is "no".

Unless the seller happened to have some other documentation, the only thing you can do it use the parts book to try and narrow down the range of when it would have been built.
 
I was afraid of that. With what we found we beleive it is a 47 or 48. Stamped frame, new style draw bar, and no nut on outside of brake drums. Problem is that when ordering parts from our local JD dealer they "say" they require a serial number.
 
Narrow it down as best you can and then make up a serial number that matches the date, or tell them the serial number range the tractor falls within.

There is a list on this site of serial number/years.

The other thing you can do is get the part book (free download) and determine the part number yourself. Order by the part number.

'm with Kurt. Pick a number. 215215 would be easy to remember and about midway between the first (199744) 47 and last (230043) 48. There were very few changes made in the first two years that would cause you problems.
 
A guru, who posts on this foirum has done some research with casting codes. He might be able to narrow ndown the build date. But there is no way to positively identify the serial numbver without some other reference. Just as a precaution I would advise anyone who shows a tractor to stamp the serial number somewhere else on the machine, it's just too easy to remove a serial number tag.
 
If it has a stamped frame, it'll be a cyclone, or later tractor. Then, there's another split. The later cyclones had a square rather than round axle housing. That'll help determine the year(s).
 
I’m restoring a 48 Model B and using 51 Model B as a parts tractor. There are few differences that may help you identify the Serial number range. If you are interested, send me an e-mail and I’ll tell you where to look for pre and post 49.
 
Thanks Paul.
Heat codes on unstyled tractors are fairly easy to estimate a rough "birthdate" for, and then from there a rough build date for the tractor.
Unfortunately with the styled tractors, and to an even greater degree, the late styled ones, the heat codes aren't much help at all. If the model year is known for sure, then sometimes a heat code can narrow it down some.
Carefull examination of a parts book, and all that everyone on here has said so far is about all I think you can do.
The comment about stamping the serial number on the tractor somewhere is extremely good advice. I also advise folks to stamp the number under the tag, if they have it off while restoring a tractor.

I know this is an old thread, but I hope you can help me as I need the same info. My serial tag is there but is rusted to where you can't read it. Please take a look at my recent post and I have pictures there. My email is always open. [email protected]
