On one of my paddocks I have quite a bit of moss growing you can see some blades of grass in it but mainly moss , is it best to harrow it and put more seed down ? I don't want to use chemicals,

Keep the grass a bit longer and it will go away.

Unfortunately its not been grazed for a year or so ,

Try liming?
Scratch it about a bit in spring, birds will take it for nests.

chickens will scarify it for you, and fertilize it while they're there.

Its a strange one under the trees there is grass and in the open there is moss , I will give it a good harrow in spring and some grass seed on it

Not sure if this helps, probably expensive, but local radio gardening man was recommending a bacteria that eats moss. It sounds fairly new, he said search 'moss' and 'bacteria' .
But he was also saying moss thrives on acidic soil.
