Side view of Steiger tractor towing the Oliver test car during the drawbar test. The building in the background is the Splinter Laboratory Building, which houses the tractor test lab. The main exhaust fan can be seen on top of the building. On top of the Adams cab (silver) is the diesel fuel test tank. This tank is weighed before and after each long-term test. This was probably the Tiger ll in 1974 or 1975
