Getting ready for a rainy week of tractor maintenance. I took the sides off the 1026 and found this. I am assuming this is not normal, but I also don't see anything setup incorrectly. The exhaust has melted the black plastic in the front, and has nearly destroyed the coolant overflow tank. What I have seems to match what I see in the service manual. I'm not seeing any other mention of this in the forum or general googling. So I'm stumped.
Is it all correctly installed and something is making it be too hot?
Is the pipe and/or muffler the wrong part?
Is there some insulation or shielding that should be there I don't know about?
