Remember, those old timers have a positive ground...

 

[Wagtail]

it is a 9N2986 and it is gas

So it's a 1940 year. Good stuff! TractorData.com Ford 9N tractor information

That one has an alternator on it so it probably has been converted to positive ground and twelve volt. The only changes are an additional ballast resister, twelve volt coil and removal of the voltage regulator. Can't tell if there is an exciter wire on the alternator or if you just rev the engine to get it to charge.

I was thinking it was a 1939, it still looks good to as old as it is.

yep it's 12 volt but I have not had time to investigate what all was changed on it.

UPDATE: got the old tractor running today and that was the only good news. found out the hydraulics are not working, in first gear it has a knocking sound and it has a cracked block right where the newer version has a freeze plug. it does not make the knocking noise in any other gear so it probably has a chipped tooth. the three point hitch does not even try to move.

The cracked block is the biggest concern. The hydraulic fluid might just be contaminated with water.

Is there any antifreeze in the oil? Was the cooling system filled with water and no antifreeze? If it has antifreeze in it now, and it is not leaking, then perhaps the block cracked years ago and it has held together OK as is.

I was given my great grandfather's tractor about 10 years ago (a 1943 Case SC tricycle type - about 25 hp). I used it as my only tractor up until 5--6 years ago. It is neat to have/use a piece of my family's history- now it sits in the barn but I start it/drive it every few years.

I'm sure your son will appreciate it, even if first gear is "off limits". Some day, replacing that gear might be a project that he can share with his kids.

the Hydraulic fluid looks a little milky so your are probably right, No antifreeze in the oil that I seen and when I topped the radiator off with water it turned green so it must have had some antifreeze in it. the block looks to have been welded before and it cracked right above the old weld. trying to decide if I want to have it welded or sell it to someone that might want to restore it or use it for parts.

If the crack was repaired in the past and isn't leaking now, then it may just be cosmetic at this point.

My two cents is to take your time on making the decision whether or not to sell. I'm glad my dad didn't sell my great grandfather's tractor.

Maybe Soundguy can tell you how hard it would be to fix the issue with 1st gear (he is the TBN member that seems to share the most knowledge about vintage Fords).
