The XCMG GR1803 is a heavy-duty motor grader powered by the Shangchai SC7H190.1G3/G4 engine, delivering 140 kW (approximately 190 HP) of robust power. With an operating weight of 15,400 kg and a 3965 mm moldboard, this model is designed for high-efficiency grading, leveling, and earthmoving operations. The GR1803 is ideal for road construction, infrastructure development, and large-scale earthmoving projects.

1. Powerful and Efficient Engine
   Equipped with the Shangchai SC7H190.1G3/G4 engine delivering 140 kW (approximately 190 HP) at 2000 rpm. Compliant with China III / China IV emission standards, ensuring reliable performance with excellent fuel economy.
2. Versatile Transmission System
   6 forward speeds and 3 reverse speeds provide optimal speed selection for various working conditions. Forward speed range from 5 to 38 km/h allows efficient operation across grading, transport, and fine finishing applications.
3. High-Performance Moldboard
   The 3965 mm × 610 mm moldboard offers exceptional working range with 450 mm lift height and 500 mm cutting depth. Blade tilt angle from 0° to 90° and cutting edge angle from 28° to 70° provide maximum flexibility for complex grading operations.
4. Excellent Maneuverability
   With a minimum turning radius of just 7.3 meters, the GR1803 delivers outstanding maneuverability in confined spaces and uneven terrain.
5. Robust Traction and Gradeability
   Maximum traction force of ≥79 kN and 25° gradeability ensure reliable performance in heavy cutting and pushing operations across challenging terrain.
6. Large Fluid Capacities
   280 L fuel tank and 110 L hydraulic tank extend operating hours between refueling, enhancing productivity on large job sites. Additional 38 L transmission oil and 46 L balance box oil capacities ensure optimal component lubrication and cooling.
