John Deere X485 cold starting issues

[Dutch445]

upon further review i may be confusing this with my old 445,
there are 2 injectors for the X485.
but the seafoam is a good idea to try, will take a few
hours of running to see if it helps..

You are correct after a more detailed review of my tractor, itt is in fact fuel injected (I misspoke yesterday about it having a carburetor so sorry for the confusion..). I will try the Seafoam approach.
Also, I'm at 6,600' elevation whereas when I had the tractor a sea level, it always started on first or second crank. Could this be the cause? I would think the injection system would adjust for elevation differences??

Thank you Dutch for the great information. I will pursue that

D Michael,
We are at around 1000 feet here and my sons X485 is very slow and difficult to get stasted in cold weather. Almost worse than his X749 diesel. His has around 2300 hrs on it so that could be partially to blame.

His 425 carburated unit started much better.

My X540 also sucks t starting in cold weather .I suspect that the EPA regs have these running so lean makes them cold blooded.
