I just took possession of a Ford 3550 that was too good a deal to pass up on Craigslist. It came with a foot-high stack of service manuals, but nothing that gives basic operating info. I guess I'll have to search for an Operator's Manual. The tractor has a loader and 3PH but no PTO. It has lived outside it's whole life and it shows, but all of the basic systems work. The front kingpins are shot, and I'm not sure if a standard bushing job will be possible, but we'll see.
So for starters, my questions are what are the controls in the picture below? I'm at a loss. Is it possible to add a 3PH?
Here's the whole tractor:
