Service manual for L4150 describes a Idle Compensator mechanism which controls idle speed. Looks like the two speed idle operation is normal for this tractor. See attached.

All of the earlier L-3 series (L3350 / L3750 / L4150) have, for lack of a better term, a cold start, high idle throttle positioner. You've described its functionality perfectly...start in colder conditions, idles high, then automatically drops to normal idle after a few minutes... as mentioned, akin to a gas engine with automatic choke. My 1985 L3350 had this feature, but my 1998 L5450 (both L-3) lacks it.

My L4150 runs faster with faster idle at cold start then backs off. It is normal operation! I believe it's in the WSM but as far as I know this is all good!
