A user of Russian social network VK has discovered an eight-wheel Amphibious All-Terrain Vehicle (AATV), created in the 1950s by the Design Bureau of the Chelyabinsk tractor hydraulics plant, Russia media reported.
Weighing in at 600kg, the AATV has compact dimensions (with a length of 4530mm, a width of 1900mm and a height of 1490mm), an aluminum chassis and all-wheel drive.
The design makes use of parts from the GAZ-M20 “Pobeda”. The new owner is now trying to clarify further details of the vehicle’s history.

One of the users of "VKontakte" has acquired a unique design, created more than half a century ago by the Hydraulics Design Bureau of the Chelyabinsk Tractor Plant.
As Ivan Ivanov assumes, the newly-made owner of the Chelyabinsk Krakozyabra, this all-terrain vehicle is designed by Maxim Nikolaevich Melnichenko, the ChTZ designer who was the head of the hydrostatic drive group of the tractor GSK ChTZ. Approximate years of construction of the machine - 1950-1951.
According to the available data (which has yet to be confirmed), the authors worked on an unusual project in an initiative, privately, but the design and creation of the prototype were carried out professionally, by the whole team of the ChTZ hydraulics design bureau.
The eight-wheel car of a futuristic look has rather compact dimensions (length - 4530 mm, width - 1900 mm, height - 1490 mm), articulated design and a riveted aluminum body. Curb weight - about 600 kg, wheel formula - 8x8.
It is curious that the all-wheel drive system is made according to the hydrostatic scheme, when the internal combustion engine rotates the hydraulic pump, and that results in eight (!) Hydraulic motors - one on each wheel. All wheels have a swap system, plus for each pair of thrusters you can pull the track.
The design is widely used units GAZ-M20 "Victory". Actually, it was planned to take the engine from Pobeda, but for unknown reasons, the engine was not installed on the car. Now the new owner is trying to figure out the detailed history of the creation of this all-terrain vehicle.
