Ford 550 Backhoe Identification

[Racer 1]

I have recently purchased what I think is a Ford 550 Backhoe. I have looked at a lot of pictures and that痴 what I have came up with so far.
The ID plate reads Ford Tractor number C479611, Model DF111F, Unit 5J12B, Engine 5H15A, Transmission 5G04B. I is a 3 cylinder diesel.
Any information would be great! I have to figure out how to attach a picture.

This is from my 550 TLB manual.

From your date code, it is from Sept 1975.

Thanks for the information! At least I can get parts for it.

What do you need to do to it?
