I am a new member and joined to learn more about gators. I have an 4x2 model and 5 of the 6x4 model Gators and was looking for info on serial number to year model and was seeing members being directed to their dealer to get the info. After a long search I found the info on JD's web site under Groundscare and have posted the link to the PDF file below. I hope it gets you there. This covers all UTV's and helped me alot.
