<font color="green"> Mainly using it to mow the back 40, or should I say back 20. I'd like to get a tiller for a small hobby garden and plant some stuff for the deer in the fall. No serious dirt work in the forecast, although a FEL may come along in a couple of years from now.
I don't know if this would make any noticeable difference, the 24" lift point is 300 lbs greater on the NH than the Kubota. 1600 lbs vs 1300 lbs.

Let me throw out a semi-contrarian point of view here. The tractor will be a mowing machine. For lawn mowing, with a FINISH mower I'd choose the Kubota specifically because of its lighter weight. For field mowing the TC30 might not bounce quite as much, but neither of these tractors is particularly heavy. So for field mowing I would go with the tractor that had a suspention seat, whether it was lighter or heavier overall.
For running the tiller in the hobby garden, I would choose the lighter tractor for lower soil compaction. Afterall the point of tilling is to make the soil loose. Driving over it with heavy tractor sort of defeats the purpose. But this is not a big deal breaker in my mind that really favors the lighter tractor that much more than the heavier one.
Now switching over to the FEL. The Kubota is going to use the 402 loader (same loader I use on the
B2910). That loader, IF you ever decide to buy it, is a decent loader. Not a brute in any of its capacities, but it is capable and well matched to the light weight tractor. The NH would use the 7803 (I think?) loader. I believe it specs out higher than the Kubota's loader. But you are not even buying the loader now, and may consider it in the future.
