From the reinforced articulation joint to the heavy-duty final drives, this machine is built to deliver consistent results year after year with minimal downtime and reduced total cost of ownership.
The balanced weight distribution across the front and rear axles provides outstanding stability during cutting, spreading, and finishing operations. Combined with the all-wheel-drive system and limited-slip differentials, the GR2403IV confidently navigates steep grades and irregular terrain without sacrificing grading accuracy or operator safety.
At the core of the GR2403IV lies a six-cylinder inline turbocharged diesel engine featuring an optimized geometry turbocharger and high-pressure common-rail electronic fuel injection. This advanced configuration delivers a net output of 179 kW (240 HP) at 2200 rpm with peak torque available from low engine speeds for effortless starts under full load conditions.
The modular cooling system incorporates a cross-flow radiator and a viscous-drive fan that automatically adjusts its rotational speed based on coolant temperature, minimizing parasitic power losses and improving overall thermal efficiency during prolonged operation in hot climates.
The GR2403IV features a state-of-the-art closed-center hydraulic system with load-sensing technology and a variable-displacement axial piston pump. This intelligent system supplies only the precise oil flow demanded by the actuators at any given moment, eliminating the energy waste inherent in conventional open-center designs.
Proportional electro-hydraulic control valves respond with millimeter precision to the operator’s joystick inputs, delivering a smooth and progressive feel that translates directly into superior surface finishes achieved in fewer passes. The load-sensing capability reduces fuel consumption by up to 12% compared to traditional hydraulic configurations.
The moldboard of the GR2403IV 3 Series measures 4,270 mm in length and 650 mm in height, fabricated from high-manganese steel with surface-hardened cutting edges for exceptional wear resistance. The interchangeable tooth holders allow field replacement of wear edges without specialized tooling or extended downtime.
The fully certified ROPS and FOPS cab provides a safe and comfortable working environment with panoramic 360-degree visibility through large laminated glass panels. The pneumatic suspension seat with adjustable lumbar support, telescopic steering column, and ergonomically arranged controls minimize operator fatigue during extended shifts.

The versatility of the XCMG GR2403IV 3 Series makes it an indispensable asset across a broad spectrum of construction and maintenance projects. In highway and expressway construction, this motor grader excels at spreading and profiling granular base and subbase layers with exceptionally tight thickness tolerances that meet stringent engineering specifications.
For rural road maintenance and unpaved road rehabilitation, the GR2403IV performs reshaping, ditch formation, and cross-section restoration with an efficiency that significantly reduces long-term conservation costs. Its extended blade length covers substantial working widths in each pass, shortening project execution timelines considerably.
In urbanization projects and land preparation for residential and industrial developments, this machine ensures proper platform leveling with the precise drainage slopes specified in engineering plans. It also plays a critical role in airport construction, where planimetric tolerances are particularly rigorous and leave no margin for error.
The powertrain of the GR2403IV has been engineered to deliver consistent output under the most demanding conditions. The electro-hydraulically actuated Powershift transmission allows the operator to select the optimal gear without interrupting the power flow to the wheels, maintaining uninterrupted traction throughout speed changes during critical grading passes.
The optimized torque converter with enhanced multiplication ratio provides smooth starts even with a fully loaded blade, protecting mechanical components from instantaneous overloads. The drive axles incorporate self-locking differentials that automatically distribute torque to the wheels with the greatest grip, ensuring continuous forward progress on loose or slippery surfaces.
Oil-bathed multi-disc service brakes act independently on all four axles, guaranteeing symmetrical and secure braking capacity even on steep gradients under maximum load. The mechanically actuated parking brake system complements the main hydraulic braking circuit, providing redundant safety protection during stationary operations and equipment transport.
The closed-center load-sensing hydraulic system of the GR2403IV 3 Series represents a significant advancement over traditional configurations. The variable-displacement axial piston pump adjusts its displacement in real time according to the demand from the working circuits, resulting in fuel savings of up to 12% compared to equivalent open-center systems under typical operating conditions.
The double-acting hydraulic cylinders that actuate the moldboard are equipped with pilot-operated check valves that lock the blade position in the event of pressure loss, providing an essential safety feature during transport operations and when working near ground personnel who depend on predictable machine behavior.
The high-efficiency filtration system with visual clogging indicators protects all hydraulic components from particulate contamination, extending the service life of pumps, valves, and cylinders. The generous hydraulic reservoir capacity ensures adequate thermal dissipation even in hot climate conditions where sustained operation can challenge cooling capabilities.
The cab of the GR2403IV has been redesigned following modern ergonomic principles to reduce both the physical and mental fatigue of the operator. Large-surface laminated glass panels provide exceptional visibility in all quadrants, eliminating blind spots that could compromise safety during maneuvering in congested worksite environments.
The automatic climate control system with high-efficiency air filtration maintains a constant interior temperature regardless of external weather conditions, while in-cab noise levels have been reduced to below 78 dB(A) thanks to multi-layer acoustic insulation and resilient engine mounting supports that isolate vibration.
The integrated color touchscreen display on the instrument panel provides real-time information on all machine operating parameters, including fuel consumption rates, operating temperatures, hydraulic pressures, and diagnostic trouble codes. This facilitates predictive maintenance planning and helps prevent unexpected failures that could delay critical project milestones.
The design of the XCMG GR2403IV prioritizes accessibility to routine maintenance points. Wide-opening side panels provide access to the engine compartment from both sides, facilitating daily inspection tasks and scheduled oil and filter changes without requiring specialized tools or extended service bay time.
Engine oil change intervals have been extended to 500 operating hours thanks to the bypass filtration system and increased oil sump capacity. Centralized lubrication points grouped in easily accessible blocks reduce daily greasing time and minimize the risk of missing any critical lubrication point that could lead to premature component wear.
The onboard diagnostic system with standard scan tool connectivity facilitates rapid fault location, reducing unplanned downtime and repair costs. All electrical components are protected by IP67-rated sealed connectors that guarantee reliable operation in wet, dusty, and high-vibration environments commonly encountered on active construction sites.
The GR2403IV positions itself as one of the most competitive motor graders in the 240-horsepower segment due to its exceptional balance between acquisition cost and delivered performance.
