thinking about repairs on the 2006 ft 504a, I had to resolder the filler neck on the rediator .I had to replace the tachometer pick up, That tractor has a compressor for air brakes if you were pulling a trailer so equiped. Never used it for that ,blow up tires can run a nail gun which has been handy. But the orginal air filter was just  a small housing of foam kinda like a lawn mower uses,removed that and plumbed into clean air side of air filter for engine, now engine oil stays cleaner longer. replaced plastic fuel strainer bowl with a ford 8n type housing which is glass.just little stuff tractor has around 1000 hrs .on it. replaced filter screen on hydros and put in a 10 micron screw on filter just cause I thought the filter was better than the screen. Can not say to much bad about it.

I seem to remember that the quick connects could fail ,and when they did they restricted the flow . I believe that most people just changed them out ,instead if trying to repair them. I guess that would be something to check first at the inlets and outlets at the pump for debris fr0m the quick connects. If all is clean I guess it would have to be the valve body. Might want to look at the connectors to see if they have any filter screens inserted in them, you just never know.

It could have been a fluke but when I heated the ring gear to take it off and turn it over and then heated it again it never quite shrank down enough and when you would engage the starter the ring gear would spin on the flywheel so just be aware this I guess can happen. At the price I would go new and maybe save the old one as a just in case.

some ring gears are not directional and can be flipped over and some not, as I look at the picture of the ring gear it looks to me that it is a directional ring gear,but it might be the angle the picture was taken at. I am wondering if the ring gear was made on the flywheel and non replaceable too. I had one that I had flipped and could not get it to fully lock on the flywheel had to tack weld in a few places, it was on a tractor and the potential unballanced condition I created by tack welding did not show up because of the low rpms there. anyway it might be good to look at a exploded view of the clutch flywheel assm. and see if it shows the ring gear as a seperate piece.

not to be a wise ass but you need to run it more, something you might want to look at is the fuel, I assume that it is cold where ever you are at and it might have a trace of water in the fuel that had frozen in the injector pump governor housing. Not saying that this happened but with equipment that is not used much , condensation can get into fuels, more so stuff not kept under cover. So as stated above check the oil in the injector,smell and feel it to see if there is diesel in it ,if there is a more than normal oil  scheduled change out might be a good idea. If equiped with a fuel sediment filter look at it to make sure there is no water in it.
