I'm probably different than most. I created my username only after owning my 755 for 16 years. With still low hours and being absolutely troublefree and in great shape I saw no reason or need in the future to change. I retired in the house I built 20 years ago with the tractor I bought to be my last one. Before the 755 I had a JD 430 for several years. It was small enough to be convenient to transport until I built the house. So with my JD history even if the 755 should blow up tomorrow and need a replacement it would be another Deere and I would still be proud to use the JD755 name. So while I completely agree it is typically not a good idea to use a tractor model for your user name, there can be rare exceptions. Or is it well-done exceptions? Anyway, that's just me, JD755.
