Key Features and Applications
Cummins Power Plant and Matched Drivetrain
Equipped with a turbocharged Cummins 6CTA8.3 diesel engine delivering 142 kW at 2,200 rpm, the GR180 is paired with an electro-hydraulic power shift transmission offering 6 forward speeds (up to 38 km/h) and 3 reverse speeds (up to 23 km/h). This drivetrain provides high torque reserves, smooth shifting without mechanical impact, and efficient fuel consumption during continuous heavy-load earthmoving passes.
Articulated Steering and Tight Turning Radius
The machine combines front-wheel steering with an articulated frame structure, achieving a compact turning radius of 7.3 m. This maneuverability allows operators to negotiate tight curves, conduct precise edge grading along rural roads, and reposition smoothly within restricted work areas and road corridors.
Heavy-Duty Rear Axle with NO-SPIN Differential
The rear axle features a three-stage drive layout integrated with a NO-SPIN self-locking differential mechanism. When one wheel encounters soft footing, mud, or loose gravel, driving torque transfers automatically to the wheels with firm ground contact, ensuring uninterrupted push force during deep blade cuts and heavy scarification passes.
Precision Hydraulic Moldboard Control
All blade movements are driven by a hydraulic control system equipped with hydraulic locks and internationally supported hydraulic components for holding stability. Built from high-strength wear-resistant materials, the moldboard assembly features an adjustable slide mechanism, 360-degree circle rotation, up to 450 mm blade lift, and a cutting depth capability of 500 mm.
Ergonomic Operator Station and Dual-Circuit Braking
The operator cab provides wide visibility and features an adjustable control console and suspension seat with an intuitive lever layout to minimize operator fatigue. Operational security is maintained by a dual-circuit hydraulic service brake system, ensuring balanced and reliable deceleration across uneven grades and sloped terrains.
