Four years ago I commited the same offense against my 1951 8N after a 24 year relationship. I had both tractors for about 2 years and can to the realization that I was using the Kubota 99% of the time.
I had a friend who wanted an 8N so he has it now. You my or may not have a similar experience based on how many tasks you use the tractor for. It was nice to have two ready to go.
Congratz, I have one and it's been great. May I suggest a toothbar, makes loader work soooooo much nicer. Just watch the stump pile, the hydraulic filter is a little susceptible!
Your new Kioti looks great and I'm sure you'll like it. Welcome to the pack. My CK30hst replaced my 1948 8N but I still have the good old girl. I was going to sell it but my wife said to keep it. Smart lady. There has been times when I used both.
