JP7520, look at your serial number, I think that the end of the number will tell you what number tractor yours is. Mine ends with 034. I'm just guessing, but I think that the 7520's were made for us here in the good ole USofA. So whatever your number ends with, and you have the newest 7520 among us, then you will know how many there are. If I am wrong with this reasoning, Mahindra dealers please let us know.
