How do I get the valve head off a petrol Fergy 20?
And then how do I ensure the timing is right again?Thanks!

Does it have a Continental or a Standard engine?

I'm not sure, but it is a 1952 TEA, and was 6 volt, now converted. Does this bear any relevance?Thanks!

I asked because I don't know anything about Continentals. Anyway, the TEA has a Standard gasoline motor; that's what the "A" represents. On this engine the camshaft is in the block so if you just remove the cylinder head, you don't have to worry about valve timing being disturbed.
But! this engine has removable cylinders, or sleeves. The head holds them in place, and there is a seal around their perimeter near the bottom that prevents the coolant from leaking into the oil. Sometimes when you remove the head, the seal is disturbed and you get a leak. Once the head is off, do not rotate the engine! The pistons going up and down can also lift the sleeves.
If you unbolt the head and it seems to be stuck, you can feed some rope into a spark plug hole, and turn the engine. As soon as it begins to come apart though, stop, because of what I described above.

Thanks! That picture looks like my engine. If I remove the head, will I be able to clean the valves, or do I have to remove the valves separately to clean them? Sorry if this seems too obvious, I'm rather new to tractors.

You should remove the valve springs to check for slop in the guides. This will give you a better look at the seats, and if they are in bad shape this is the time to replace them. It's possible you'll get away with just lapping the valves in the seats with some valve grinding compound, but don't count on it - remember you're dealing with a 50 year old machine.
I agree with Rod, a shop manual is a good investment. If you've done all this stuff on cars before it's not too different, but you will at least need the specs.

It sounds like you should invest in a shop manual before you take it apart. You would take head off then take valves out and check them and replace or lap them with valve grinding compound as needed. What is the problem with the engine? I have found when working on my TEA 20 that the timing chain was worn quite a bit and quite slack. regards
