Just curious, why not Homestead? They make a model rated for 55-100 hp, I have a lighter weight version and am very impressed with the quality. Thanks.
I had the same issue on my 2501, bolt was super tight. I ran a tap through it a couple times and now I can easily unscrew it by hand. Didn't want a pin in there figuring it would rattle and drive me nuts.
Also in WV, welcome! My tractor did include the 3 point arms, also the drawbar. Delivery driver almost forget to give them to me, he had them in the truck.
2nd the rhinohide, have one on my L2501, easy to remove to put tractor in garage.

I know Forscan can get rid of the door chime, among other things. Not sure on the airbag light. Try checking the superduty forum, https://www.ford-trucks.com/forums/forum5/
Not sure where in Maryland you are, but I picked up a set of 42" Tar River ssqa forks from Antietam Equipment this summer, around $800 and in stock. They are in Hagerstown.
Not hip, but double knee replacement. My #1 advice is to do your pre and post op exercises. And be diligent about PT. Take your pain meds when you need them. And walk. Good Luck!
