The ST-21 wheel motor grader is equipped with a Cummins 8.3L turbo engine, delivering 160kW of power and 980N·m of torque. It stays stable under heavy load and supports continuous road construction work.
With 360° moldboard rotation, ±90° tilting, 970mm cutting depth, and 1950mm shoulder reach, this machine is built for accurate ground leveling and efficient surface finishing.
Fuel consumption is only 223g/kW·h, and the 360L tank supports more than 12 hours of continuous operation. This helps reduce downtime and improve daily productivity.
Front wheel ±50° steering, articulation ±23°, and a 7.5m turning radius give the grader excellent maneuverability. It performs well in narrow working areas and complex site conditions.
The 20mm wear-resistant moldboard, planetary rear axle, and no-spin differential improve durability and traction. Optional front blade and rear ripper make the machine more adaptable for different job requirements.
A 3400mm cab height, optional AC, and electro-hydraulic control improve operator comfort and ease of use during long work shifts.




ST-21 is a medium-to-heavy duty motor grader powered by Cummins engine, featuring electro-hydraulic transmission and high-precision moldboard system, ideal for road construction, mining, and land leveling.






We possess CNC cutting equipment and comprehensive testing platforms; every unit undergoes dynamic testing before leaving the factory to ensure quality control.
