Key Features and Applications
Reliable Weichai Power and Matched Drivetrain
The GR1003 is equipped with a Weichai WP4.1 turbocharged diesel engine delivering 75 kW at 2,200 rpm. Featuring high torque output and a substantial power reserve coefficient, the power plant pairs with a multi-ratio transmission offering 6 forward speeds (up to 38 km/h) and 3 reverse speeds, ensuring efficient power transfer during low-speed grading passes and rapid jobsite transit.
Compact Dimensions and Articulated Maneuverability
With an articulated chassis structure (frame steering angle up to ±27°) and a large steering angle front axle, the GR1003 achieves a tight minimum turning radius of 6.0 m. This compact geometry enables agile maneuvering along narrow rural roads, agricultural pathways, residential streets, and restricted construction boundaries where standard-size graders cannot easily operate.
Optimized Blade Profile and Hydraulic Efficiency
The machine features a 3,048 mm moldboard designed with an optimized blade curvature that turns and ejects material efficiently. This design maintains smooth soil rolling, balances grading loads, and minimizes material buildup in the circle area. Full hydraulic control allows precise blade adjustments, achieving up to 310 mm lift height and 350 mm shoveling depth.
Diamond-Shaped Cab and Low-Effort Controls
The operator station features a diamond-shaped cabin mounted on a six-point damping system to isolate vibrations. An optimized control linkage layout reduces operator control effort by 30%, while adjustable seating, intuitive levers, and wide sightlines ensure operator comfort and visibility across extended work cycles.
Accessibility and Maintenance Convenience
Daily maintenance is simplified through a rear-tilting hydraulic lift engine hood with a large opening angle. Routine inspection points, filters, and fluid levels can be serviced directly from ground level, reducing downtime and streamlining regular fleet servicing.
