Caterpillar D8
Cat D8 H 22A when we first bought it in about 1994. Working in a gravel pit at Homersfield in Suffolk.
The same tractor after we fitted a cab to it.
At work near Swaffham. These fields had an exceptionally hard gravel-like pan about 2ft under the surface. It was so hard we could only pull one tyne in the ripper.
