I agree with you regarding Kubota. I've owned Deere, Ford, and Ferguson. But for cold weather starts after long periods of non use, that 1957 Ferguson F40 was second to none.

My 1952 Ferguson started the same when it was hot or in a deep freeze..one quarter turn of the engine and it purred like a kitten. It was amazing that way.

If you're buying from a dealer, make sure it has the emission system updates for operation in cold conditions.
Enjoy.

I would make sure the required updates have been completed to the tractor, whether buying from a dealer or not. There is a mandatory "campaign" where these machines must be brought in to a servicing dealer and checked out with the reformer, thermostat, etc. replaced as needed.
Just as an update with mine, once the reformer was replaced and the required work completed, I have had no further complications. However, a heads up to anyone who reads this - my machine starts autoregens at around 12-13 hours, but the run time between regens decreases about 1 hour every time. So after about 8 regens, it was doing it every 4 hours, which becomes a real pain, since it takes 30 minutes and the machine cannot be shut off during the process. There for awhile it was like playing Russian roulette every time I cranked the engine for a short task, hoping that it wouldn't autoregen. When it got down to a 4-hr interval, it required a parked regen, which then bumped the interval back up to 12-13 hours. The machine now has around 130 hours and runs fine.
Frankly, I feel that is a little frequent, but I can live with it. At around a 12 hour interval it's no problem, but when it gets down to 4-5, it becomes a pain. I wish they had engineered this DPF, or at least the replacement for a little longer interval. At 20-30 hour intervals, it would really be a non-issue.

I should also add that I tried to make it do a manual parked regen in advance when the interval started becoming short, and I couldn't get the tractor to do it. I had to wait for it to "ask" for a parked regen to perform one. Not sure if I did something wrong or you can't make it park regen on demand.

Don't believe that you can ask for a parked regen. It would be more convenient. Maybe with the next iteration!

I haven't had any updates done to my Nov 13 B3350 yet. Now with 269 hours, the last two "running" regens were at 247 and 266 for 19 hours between. Not bad I guess.
Now I do try to run at >2000 most of the time, but when spraying or other low power work, will sometimes run at >1800. On my early model, the default is for no auto regen. I have to push the auto regen button to enable that feature, and I'll do that if I'm doing something with the tractor that I know will take at least 20 minutes. For quick stuff, like moving the tractor or lifting something, I just don't push the button. Then if it wants a regen anyway, the regen light will flash but only as a warning that it's needed. If ignored, and auto regen is not selected, or if it is selected but RPM isn't high enough (>2000), then it will finally ask for a parked regen - I've done that only once. I have interrupted an auto regen in progress - - I'm sure it didn't like that, but seemed to handle it okay as I pushed the auto regen the next time I needed to use the tractor and it did the regen then.
I understand that later versions default to auto regen each time they are started, but I'm okay with the way mine is set up.

Glad I read this thread. I just priced a B3350 today with loader, 72 belly mower and catcher. It very seldom get below 15 degrees here and I never blow snow, (thank goodness). Seems that all of this regen issue is happening in colder climates. Even so I may consider the smaller tractor.
Anyway, My GL5740 needs a playmate so I'm looking.

I did some serious cogitating about the differences between the B2650 and B3350. Considering power loss to altitude for normally aspirated (3% per thousand feet), I went with the turbo. There have been times while bush hogging, that all of that was needed and a bit more, and that was moving slow, tall, thick grassy weeds. Though normally it doesn't so much as hiccup, plenty of power.
Still, if I were doing it again I'd seriously reconsider the 2650.
