Worzel Gummage with his 'Happy Head' on.
He is a fictional scarecrow and lives at Scatterbrook Farm. He has a set of interchangeable heads of turnips, mangel wurzels, and swedes, each of which suited a particular occasion or endowed him with a specific skill. His best friends are two children who live nearby, called Sue and John, and are always running to his rescue and getting him out of trouble.
In the book he had a wife called Earthy Mangold, sadly in the TV series there was hardly any mention of her, which is a shame because apart from having such a glorious name she was quite an eccentric and quirky character.
