So picked up a 3025E new from the dealer at a good discount because it was a new 2017. The question I have is it has all the updates as a 2018. 300 loader ,rear fuel fill, new body style, new dash board, Even the pto switch is the toggle. How do I tell what what year it is by the serial number. It’s. 1LV3025EAHJ. I think the H is the year date code but I don’t know what it means. Any help would be great.
