24 FOUR TRACKS RIGID VEHICLES, MEDIUM

Donzilla Four Tracks Vehicle was built for agricultural use in 2002 by Don Kauer in a small farm near Hillsboro, Oregon. Four rubber tracks, of Taeryuk Rubber Company, were fitted on a sub frame, itself bolted on a street pickup without any cuts and drilling holes. Speed reached 40 km/h without overheating of the tracks and the tests were good. Nevertheless, tracks were noisy, too heavy and unsprung mass too high. Unfortunately, it was dismantled the same year. A video is owned by Taeryuk Rubber Co. Pict. Don Kauer.
