This paper introduced the development of 450×90KB×51 agricultural rubber track. The outer compound, inner compound and steel cord compound were NR/SBR blend, composite rubber/SBR blend and composite rubber, respectively. 45# forged steel was selected for metal core which was designed to have a load capacity of 0.6 time of the frame and the width of the metal core was 42 mm. The number of steel cord was 56 and the cords were coated by copper/zinc coating. The diameter of steel cord was 2.0 mm except for the middle cord which had a diameter larger by 0.36 mm. Z-pattern was applied in tire tread with a width of 45 mm and height of 35 mm. The experimental test results showed that the physical properties of the compounds, load capacity of the metal core, the strength of the steel cords reached or exceeded the requirements in national standard, GB/T 20786—2006. It was conifrmed that the adhesion between rubber compound and steel cords was good, and the product quality fully met the application requirements.
