That does not sound good. I have no idea what is causing that.

I've owned two L6060's and have not experienced this with either one. If the tractor is new or still under warranty, I'd call the dealer.

Whether it's under warranty or not, I'd check in with the dealer. The tractor is probably computer controlled, that is the computer sets the throttle, not you. One of the sensors may be defective or the computer itself could have issues. It is not good to go full throttle on a cold engine.

Lets take care of the obvious first, you do have the throttle/rpm lever all the way down correct?
Is it trying to do a regen?
I ran an electronic search through the user manual just to be sure and I dont see anything that would kick the rpm up automatically just because its cold.

I’m thinking that it might be related to the block heater? It should only be used for a couple of hours prior to starting the tractor. If it’s always plugged in there’s the risk of internal condensation at the colder edges of the engine. Maybe there’s a linkage that freezes up due to moisture in subzero temperatures? Keep us posted.

Electronic controls or mechanical, they all start at full throttle or the fuel rack advanced.

There is a method to enter a menu on the L60 series that may display error codes. I've never tried it, but I pasted the procedure below.
I have never had my L4060 act like that, with or without the block heater. I got this procedure likely from a TBN user.
1. Press Display mode button and hold
2. Turn Key to On
3. Several modes will appear
4. Press Display Mode until "D" is highlighted
5. Press and hold display mode for more than 2 seconds
6. "Want to clear codes? Hold button for 3s more" Will appear
7. Press and hold Display Mode for 3secs
8."Cleared" will appear
9. Turn key to "off"
Then your computer should be reset. Mode "A" is a diagnostic mode and gives information about your temps, rpms and volts going to switches on the unit, kind of neat to look at and could be helpful in the future.

Ok….but shouldn’t it adjust to a reduced setting at startup?
