Any of the premium UTF's will work equally well in an N-series so let your wallet be your guide. I have a TSC nearby and try to buy a couple pails of Traveler UTF when it is on sale which is often. I use it in my older common sump gear drive Kubota and the 8N. If I had a Rural King nearby I would comparison shop their house brand and the Traveler. You can also find house brands of premium UTF at places like Walmart/Sam's club and auto supply houses like Advance or Autozone. They are seldom on sale however.
I have a couple newer Kubotas with HST transmissions and I use Kubota Super UDT2 in them. Same sort of oil but with a slightly lower viscosity and considerably higher viscosity index. The difference in price is significant - $5-6/gallon for the Traveller UTF and $20+/gallon for Kubota Super UDT2. The Kubota branded oil MAY perform a bit better in the hydrostatics and it gives me a warm fuzzy feeling because Kubota engineering likes it. It would be a massive waste of money in the old 8N and the gear drive Kubota neither of which would benefit from the performance difference. Plus the Kubota leaks like a sieve. Whatever you use the key to getting the most out of it is keep it clean and free of water.
