Hi,
Earlier today over in the Late Model Tech forum I referred to the Serial Number Magic Decoder Pin here in the FAQs.
The model serial number of a John Deere lawn mower is printed on an identification tag located on the left side of the deck (standing behind the mower). The serial number (PIN) is 13 or 17 digits long. Model Year Serial Number Chart Rev. 30-Jan-2012 IMPORTANT: The model year and serial number chart below shows the vintage of riding lawn equipment.
