My 4310 loses power after warming up and blows white smoke. I changed fuel filter, drained tank, changed air filter and refilled tank with new fuel and Heet. The issue continued. This all started while mowing. The RPM drops way off also. The local Kubota Dealer kept it for a week without being able to duplicate. I was told they let it run the better part of a day. The fuel flow was fine according to them and no issue with rpms. I may mention I had them adjust valves while it was there. When I got the tractor home it started doing the same thing after 10 minutes of running finish mower. Called dealer and the mechanic said it sounded like an injector trying to stick. Told me to add automatic transmission fluid to fuel. After doing this it cut grass for around an hour then began doing the same thing. Does anyone have any ideas?

Why heet, it's not freezing where your at.
Have you treated your fuel for algae?
I would do that and if it continues pull the injectors and have them tested.

I'd find a younger mechanic! Adding ATF was something done to supposedly lubricate the injectors about 40 years ago.
Sounds like the problem occurs when the engine is under a load, and if the shop just let it idle all day the injectors may handle that. Might try an additive to clean the injectors or take them out and have them tested for spray pattern and pop off pressure.

First of all check vent in your fuel cap if the tank can't get air in it will caused the problem your describing !
Sounds lime injector sticking open
You should hear a miss from the cylinder that the injector is sticking open on
If the injector is sticking open hold each injection line at a safe easy place you will feel a vibration from the lines if one or more Lines has a lot less vibration that's your bad injector
