The KZKT-7428 Rusich tank transporter artillery tractor was developed as a successor to the MAZ-537 by KZKT. It can haul semi-trailers loads up to 70 t, both on and off-road. It entered service with the Soviet Army in 1990.
As early as the 1970s, there were efforts to replace the first widely used and by then outdated Soviet tank transporter MAZ-537 with a new design. The main task for the developers at the Kurgan Wheel Tractor Plant (KZKT) was to increase the engine power. In the mid-1970s, prototypes such as the KZKT-545 (with a W38 diesel engine and double cab) and the KZKT-7426 (with a D12A-650 diesel engine) were produced, but neither went into series production. The main reason was the shortage of powerful tank engines required for these models.
In 1978, political directives were issued to KZKT to develop tractors capable of towing loads of 150, 300, and 600 tons. The result was the KZKT-7427, equipped with a D-12AN-650 diesel engine (38.88 liters displacement). Again, the availability of such engines was poor, and their service life was too short — they would wear out after just one year of normal use. Therefore, it was decided to replace the tank engine with a different V12 diesel engine, the YaMZ-8401, from the Yaroslavl Motor Plant. Although it also produced 650 hp (478 kW), it had a smaller displacement of just under 26 liters. Testing of the vehicle began in 1985.
Based on the experience with the KZKT-7426 and 7427 models, the KZKT-7428 was developed in the late 1980s. KZKT used the same YaMZ-8401 diesel engine model also used in dump trucks from the Belarusian manufacturer BelAZ. The trucks passed all tests and were recommended for series production, which began in 1990.
Compared to the MAZ-537, the cab, transmission, and engine were modernized. The engine was positioned directly behind the newly designed cab, which accommodated the driver and five additional crew members. The vehicle typically featured all-wheel drive with single tires on each axle. KZKT produced not only a four-axle (8×8) version, but also variants with three (6×6) and five axles (10×8). Production ended by 2011 when the manufacturer was dissolved due to insolvency.
