The Digger is a scoop tractor that is owned by some workmen. It is used at the quarries to dig as well as lift and push rocks. Occasionally, it was seen at Knapford Harbour. Once, 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 70 - the largest, and last, design of petrol-powered tractors in Caterpillar's range. Terence is another member of this class.
The Digger was painted yellow in Christmas Crisis.
