john deere 855

I have a John Deere 855 i use for mowing with a 72" belly mower on it. The tractor is in good shape and it start up as soon a you turn the key and runs great with 1706 hrs on it. i dont know if im just being paranoid since i love this little tractor but it smokes white when its cold and until it warms up. Not a lot but enough haze to notice. Once its warm no smoke it runs clean. Just wondering if the injectors need tested or if its normal?

No one?????

my 1070 with 5216 hours on it does the same if it is below 50 degrees outside, far as I know injectors have never been out of it.

I have a 430 with the same engine as the 855. Got around 4k hours now. Also has a little smoke when cold, I would not worry about it too much. Injectors might be getting a bit lazy. Run it! I've been pushing the 430 hard for the last 1500 hours mowing 8 acres in summer and plowing a 1000ft driveway in the winter and nary a whimper from that little oil burner!
