Truck tractor manufactured in 1958 – 1964 with a permissible load on the coupling device of 25 tons. It served as part of road trains with a gross weight of up to 90 tons. It towed low-frame 65-ton semi-trailers for the delivery of tracked vehicles, oversized cargo, heavy weapons and missile systems. Its design has been carried out since 1956 and was carried out in parallel with the development of the “small” ballast tractors MAZ-535 and MAZ-536, but with the reorientation of the USSR Ministry of Defense to heavier weapons systems, all work on the 537 topic acquired a special priority and were activated.
A D12A-525 V12 diesel engine with a power of 525 hp was installed. with preheater, dual start system, circulation lubrication, alternator with built-in rectifier and a whole long chain of hydromechanical transmission units with self-locking differentials, 18 cardan shafts and wheel reduction gears. The four front steered wheels were also suspended on an independent torsion bar suspension, but to ensure increased strength and load capacity, the rear balancer suspension consisted of two powerful lateral longitudinally swinging levers, rigidly mounted on a reinforced trough-shaped riveted-welded frame with channel-section spars. The saddle version was also equipped with a piston power steering, a pneumohydraulic brake system with drum actuators. Three headlights with ventilation hatches were also placed on the front wall of the cab. On both sides of the engine compartment there were five narrow and high air intake hatches.
