Aparently these tires have tubes, my buddy said the tires can be repaired (they still have very deep tread and are not dry rotted) but have a couple gouges in them and then they just need need new tubes.
Nooooo idea how I would get them off the rims though. A little beyond a tire spoons capability...
Break the bead loose with a sledge, spoon off tire.
Parts are everywhere, Dennis Carpenter and Steiner have just about anything you could need.
Not having live PTO isn't a big deal once you get on to it. Aside from the hand clutch thing on my bigger A-C's nothing I have has true live pto.
Depending on what you do you don't HAVE to have fluid in tractor tires, a lot of them are dry. Only one of mine has fluid in it (and it is the nasty stuff)
One thing about Ford... they didn't copy anybody. They had their own little theory about how to do things and if you are used to a different color there are a lot of oddities about them.
Moneywise you gotta do it for you, it will be hard to break even. N series used to be really popular but I think the new compact tractors like Kubota kinda gutted the market. Radiators and tires will kill ya. Hard to buy a tractor worth $800 running/driving that needs a $300 radiator and $500 worth of tires and come out ahead.
My last one when I got it (for free, had been sitting since the mid 80's)
A new radiator, used tires, new water pump, valve job, alternator/wiring and carb rebuild later it is my #2 horse... and a running WD is worth about $800. $1500 with new tires and nice paint.
