Four tracked vehicle. Pict Francis Pierre, late 90s.



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.

It is an honor to have my rig on this awesome and very valuable site. To what email addy can I send further information and pictures? Thank you. Don Kauer.

Hi there. Donzilla is not hydrostatic, nor was it made in Alaska by team Lance. It was made by me, near Hillsboro Oregon in 2002. The pickup's transmission and axle gearing was the sole form of power transmission. It has since been dismantled. If the owner of this site would like more pictures and information, I will gladly offer it. Thanks.
