Kubota L4740 sold now have a new L2502 as off Jan 2023
Even at not so cold 5 celcuis or 35 f, my new L2502 runs rought and smokes like crazy for about 3 minutes. There will be no mice or rats survive in my garage.

Anybody else have this trouble?

Both mine smoke a bit when cold. Nature of a diesel that you cannot get away from. Incomplete combustion in cold cylinders.

Are you using the glow plugs?

I thought you was going to force the dealer to take that tractor back…..

My L4740 kubota made a few puffs but this bellows between 1 to 3 minutes.

He gave me the option. It was down 2 litres of udt. One litre to show on stick. He gusnaenteed the tranny and gave me $500. Only 2 hours on it should I don’t think it was hurt.

I just get a little puff on the l3800 when it starts . I use Power Service fuel Supplement all year long... (white bottle)

I mean, with no DPF, that's normal

Nope, when it is really cold our Kubota will smoke and run rough for about 15 or 20 seconds max after starting. Then it settles down, runs smooth & no more smoke at any constant RPM.
However, it will always blow a gust of black smoke when changing RPM no matter if it is cold or totally warmed up .... always has done that.
