I'm looking at buying a used TTHP 52" that is a year old. I've talked to my local Exmark dealer and he said he can handle the transfer but I forgot to ask about the specifics. Is the serial number entered into a database when it is sold for the first time so the true date of purchase is recorded? Will I need the original receipt from the person I am buying it from or will my local dealer just look at the machine? Thanks for the help.
