The magneto serial number listed for each engine is handwritten in the ledger. I found the letter at the John Deere Archives, and they gracefully let me copy it. I work at a John Deere dealer, I have gone through the process to get replacement serial number plates. It can be a lengthy and complicated process, if you have a good dealer in your area they should be able to talk to there TCSM, which is there territory rep from Deere.

Just bought a used GT 235 with a 44 inch Pirahna deck. The mulching blades have been replaced to make the deck a rear discharge. Someone's got a nice 54C deck advertised on the local Craigslist ( http://watertown.craigslist.org/grd/3929622703.html ) and I'm trying to find out if I can use it with this tractor.
I can't seem to find a place to decode the tractor serial number to get more specific information about it. I signed up at Engine Information Search from John*Deere but I get no results for the serial number.
Is there anyplace on the internet that I can find this stuff out?
Edit:
After poking around TBN a little, it appears through some other threads that this info is apparently available only through the dealer network. Most likely via the parts & service departments.
At any rate, would any of Deere guys here have any idea if this deck would work on the tractor? Tractor serial number is MOG235A016330 if that helps anyone. Thanks!
