    Smoke when starting engine.

    The engine on my 1025r smokes a little when I start the engine the first time after it has been sitting a couple of days. I don't know much about the Diesel engine on this tractor. The smoke concerns me a little a bit. On a gasoline engine if this was happening I would think a little oil has slipped past valve guide seals into the cylinders. But on a brand new engine this should not be happening.

    Anybody else out there had this experience?

    P.S. I am sure glad for Green Tractor Talk. As a new JD tractor owner I don't know where else I would get the kind of information I am getting here. So far I am not impressed with my dealer. Now that they have my money getting anything from them hasn't been easy.

    Completely normal for a few (10 seconds or so) of smoke and rough running from a 1025r.

    HOWEVER Color of smoke and length of smoking can be important. If you post a video we can certainly give a more accurate impression

    Additionally do make certain you do not start the engine until the Glow Plug light goes out

    I guarantee there is not a person here whose 1025 doesn't smoke during a cold start. It's what they do.

    I wouldn't worry unless you had excessive blue smoke when working it hard and after its been warmed up.

    I agree with AJgrn78,

    To elaborate a little, diesel engine smoke/exhaust symptoms usually mean:

    Blue smoke: oil burning in combustion (maybe okay on cold start, not good on a hot start or when under load.)
    White smoke: un-burnt/raw diesel in the exhaust (maybe okay on a cold start on a very cold day, not good on a hot start or under load).
    Black smoke: heavy load or maybe incomplete combustion, on a cold start. Black smoke on a hot/warm idle is likely bad injector timing or fueling issue.

    Of course, this would be on an engine that does not have a DPF/smog/emissions set up since the smog equipment masks a lot of smoke.

    As others have said, white smoke and rough idle at start is normal. It gets worse in cold weather. If you cycle the glow plugs twice, this will help. Simply turn on the ignition, wait until the glow plug light goes out, then turn off the ignition and right back on, wait until the glow plug light goes out again, then start the engine.

    List of toys: 1998 Cummins Ram (12Valve), 2006 Jeep Liberty CRD, the 1025R - and they all do it!! As Ray PA said, when its really cold double cycle the plugs (curiously we do the same with the Dodges and their intake air heaters - no glow plugs). Length and type of symptom determines if you need to call the diesel doctor!

    Thanks for the tip about the glow plugs. That's a new one for me. That wasn't an issue for the "big" farm tractors I used to drive as a kid.

    The smoke is only on a "cold" start. I haven't had it long enough to know what it would do in cold weather. It's not blue smoke so I guess I am good there, too. And I have never seen it smoke under heavy load. Out of curiosity, what does blue smoke mean?

    Thanks!

    I am pretty sure it is white smoke I am seeing. I'll pay more attention next time I start it cold. Thanks
