Glad you, your family, and your home all survived that mess. Here's what I'd do:
1. Call insurance company, make a report, ask for someone to call you. I agree, you're going to want to have such a low-hours basically new mahine gone over, to make sure nothing is wrong, esp. given it suddenly sounds different.
2. Pop open and replace air filters. Save the old in case insurance company wants to inpsect. Check all fluids, make sure all is good, but I can't imagine fluids were affected much if plastic bits on tractor survived the heat.
3. Get back to work, while you wait for the insurance company to get around to you. If many were affected worse than you, it might be awhile.
