The project also had a second control place. A hydraulic brake system included vacuum booster. Beam axles were installed on transverse leaf springs.
According to all the dimensional parameters ADZK tractor was a small passenger car. Its wheelbase was 2000 mm, length – 3870 mm, width – 1720 mm. The car can carry up to 7 people with light weapons, or tow a 2-ton trailer or a gun. Max speed was 75 km/h.
In 1937-1938 was built several chassis, which became the base for experimental tractors ADZK and for three short wheelbase staff versions ADFK with open bodies. Another chassis with more powerful engine became the base for armored trucks ADSK.
