It's not in the owners manual, so I guess it is in the service manual, which I don't have. I am going into the City today and if I have time I will swing by the dealers and see if he has any L series tractors that he will start up to see if they do the same thing. I will also ask about the temp reading access.

One thing I always do is purchase the WSM for mine. The WSM really tells you everything you might want to know. The owners manual really tells you nothing except required maintenance and a bunch of don't do stuff.

Agree. The Service Manual is written by Engineers, the Owners Manual is written by lawyers.
And the sound I heard, (my opinion is meaningless) just didn't sound rythmic. Didn't sound like it had anything to do with the engine itself.
But that's from a youtube video so that is worthless. It just sounded -- Different.

If I put any credence in you tube video's and comments on this site from people, my head would explode. It hasn't yet because I take most everything on YT and here as entertainment and not much else.
People today seem to have way too much idle time on their hands so they complain about nothing that a little common sense would rectify.

If I read that right, those are the Owners Manuals not the Service manuals. I already have the Owners manual. I will check into getting the Service Manual. I downloaded the Service manual for my skidsteer and that is very informative and has helped me troubleshoot / repair a lot of stuff on that old machine. I think it was $20 CAD. Well worth the money.
So I went to the dealers today and talked to their head mechanic. Great guy and very helpful. I told him about the information "Like Tractors" offered and he said it made sense to him ( I hope I got the information right). He offered to start up a new L4760 and we both listened to the engine from start up to warm up. Immediately after he started the tractor I noticed the engine was quieter than mine but that could be due to the fact that the tractor is new and was not turbo'ed (according to him). In any case we both listened to the engine and around 3 minutes after start up I thought I heard a slight change in the engine sound but wasn't sure. He said he didn't hear any change but we were talking at the time and maybe he missed it. The change, if there was one, was almost imperceptible. Right after, what I thought to be the sound change, he pulled up the engine temp on the Intellipanel and it was 29*C. I suspect the change occurred around 27*C as "Like Tractors" suggested.
My take from this is; 1) my memory is correct, in that my tractor did not experience this noise change when it was new and 2) "Like Tractors" information is probably correct about the change at 27*C. I say probably because I only thought I heard a change and the mechanic did not hear one. I'm going accept the 27*C change as being correct (thank you Like Tractors) and attribute the louder noise on my tractor, to it having some hours on it.
I ran the tractor for a few hours today and got off to listen to the the engine, afterwards. It sounded fine and quieter than it did at start up.
I was told that the tractor still has Emissions Warranty and Drivetrain Warranty for a few more years, so if there is something wrong with the fuel system, it should be covered for a few more years. I will mull this over for a bit to decide if I will take the tractor in for a checkup or see if the noise changes.
I want to thank "Like Tractors" for his technical input. Much appreciated.
For those suggesting I am not using common sense, I offer a
. I have a very logical mind and common sense tells me that if the sounds coming from my machine (be it a tractor, truck, car, excavator, skidsteer, etc.) change then there might be something wrong and it's best to investigate before it becomes a very expensive repair. That logic has saved me many times over the years.

I would still have the dealer look at it. Yes it's kind of a pain to get it there but once they look at it then it's documented. I wouldn't doubt that the tractor's computer could make an adjustment at a specific temperature and I know cars often learn as they get used so when new it could have been quieter and now the computer is making a larger adjustment. It could also be, in part, that now that you have more seat time on it you are more in tune with your tractor. How many times have you read of a person saying the mechanic didn't hear or feel what the owner has?
After downloading the WSM, I set the Intellipanel to show the engine temp and just as Likes Tractors said, the increased noise started exactly when the engine temp hit 27*C. I will pass this info on to the dealer's mechanic I was talking to and see if he still wants me to bring it in. I'd prefer not to go through the hassle but might still consider doing so. The rush is however over, since I found out there is still lots of warranty on the components that are involved.
If nothing else, I have learned something new and acquired a WSM for the tractor.
Thanks guys!
