I have a new JD 2520 with 14 hours on it and everytime I start it for the first time in the morning I get alot of white smoke from the exhaust. it lasts about 10 to 15 secounds then clears up. I checked for water in the fuel and seems to be fine. Is this normal and why does this happen. Anyone else have the same issue with the 2520.

It is normal my 3005 does it although it doesn't seem as bad when running on road diesel rather than off road (dyed)

As noted Normal, mine stopped doing this around 60 hours, today you might see a puff of black/blue, I honestly do not pay attention anymore but i recall when they were new, especially the 2520, I went to the dealer twice. For whatever reason she is one cold blooded engine.

I guess it is all in the definition of "a lot". I see a puff of smoke with my 2320 but it doesn't last more than a second or two. If I saw a lot of white smoke, I would worry about water leaking into the cylinder head somehow. Since you only have 14 hours I'm guessing it is still covered under the warranty. Why not take her in to be checked, or maybe take a picture and show the dealer what you are seeing and see if he/she thinks it is a problem?

Does your engine crank for awhile before starting??

I get white smoke from my old ford diesel in the wintertime when it doesn't start right up. This is unburned diesel / air mixture.

Yep, My father in law's ford 3930 puff a little smoke when it first fires up, but it only lasts a couple seconds, and it has over 4K hours on it...I would load it up and haul it right back to the dealer.

White smoke, sometimes called cold smoke, is normal on most diesels starting on cold fuel. As long as it clears in 10-15 secs I don't see a problem. Cheaper refined fuel will also enhance the condition.

Didn't even think of that one...yeah the glow plugs do have to warm up. He'd probably have trouble starting it also if he was doing this.

Yes I do wait for the glow plugs to warmup before starting same with my jd455. I did stop at the dealer and asked they said it is normal and refered to it as cold smoke as well. This morning I started it at a low throttle and just saw a puff of black smoke same as 455. Thanks for the replys.

YUP thats what its called COLD SMOKE. Man I've seen alot of it. In farm tractors and big trucks that I drove over the last 60 yrs. Only worry if it continues for longer than a few seconds.

Like sikpk says, let it cytcle until it "clicks". My 2305 then cranks about 1/2 turn before firing & i"m using off-road deisel. Just a quick black puff and it's purring like a kitten. Protracted white smoke would bother me

2520's do not have glow plugs, this is the issue with this tractor, it has a manifold heater and there is no click like the 2305, simply wait for the light to go out but they will still smoke some on start up, as you get the hours on there is little smoke.
