The Digger is a yellow and orange tractor with a scoop attachment which closely resembles, and may even be based on, Terence.
It was part of a convoy that helped restore power to a village on Christmas Eve.
The Digger is based on a 1934 vintage Caterpillar Model Seventy - the largest, and last, design of petrol-powered tractors in Caterpillar's range. Terence share the same basis.
