1960's Case ???

Short version, friend called "come look at this tractor I'm gonna scrap". Guy he got it from son had some money issues and stoled the batterys) and the radiator, and the lettering of this tractor, so the old man was mad and sold it to my friend and hes gonna scrap it.

What I need to find out is if I can get it running. Here's what I can offer so you guys can help.

Looking at pictures here on ytmag it's got to be in the 60's to late 60's, bigger than a 530, not near as big as a 930. Its a four cylinder Diesel. There's a high and low range on the shifter, showing 8 speeds, decompression valve on the engine, no alternator, generator starter combo. There's a hydraulic clutch? And a lever that connects to it as well. I guess high and low?

What I tried to do tonight was pull start it to see if it would fire, but, the engine will not turn over. Is this to do with the hydraulic clutch? Whats the trick to pull start, or what kind of voltage is required for a tractor of that style, 12 or 24 .

Theres no tags on the tractor anywhere so this is about the best I can do. I did not think to take the camera and get a picture, but, I did not thing a deal was going to fall in my lap. If I can get this to fire than I fix it and use it on the farm, if not off to the scrap man.

Thanks

I'll post a picture latter tonight, I'm heading out the door in a minute and I'm on my neighbors computer.

Thanks for the info too, Brian

Its a 12V tractor, stick a battery from one of your cars on it and see if the engine will turn over. This information would be useful to a potential buyer.
