The MAZ-528 wheel tractor for operation with pushed and towed attached and trailed implements equipped with 10 backward speeds and 10 forward speeds, was the first project developed by SKB-1 in 1955. Foundation of SKB-1 Special Design Bureau for heavy wheel artillery tractors and related engines with the testing facilities.
