Reminds me of the way the farm had to help the contractors get their huge expensive four wheel drive tractors out of the pit as the level sank. Their spreader trailers were rear discharge so no pushing with the drot that was assisting the hymac to load up.
An elderly Fordon had it's wheels swapped for metal ones like below, but I recall them as being more like 1/4" thick American spade shapes than the gear teeth on the image.
Drove it back to the workshop once we finished, oh boy, thud, thud, whole machine whacking down on hard surface, thank heavens for the old on the end of a curved spring metal tractor seat.

Drot is a bulldozer with a split loader style bucket, back works as a blade when the edges are swung up like a hinged hoop. Not sure if it's a Hertfordshire term or what.
