NEW SKY Grader: Built for Global Infrastructure Diversity

XUZHOU, China, July 24, 2026 – As global infrastructure spending faces tighter budgets and project owners demand higher equipment utilization, NEW SKY, a Xuzhou-based construction equipment specialist, has answered with a strategic expansion of its motor grader portfolio. Today the company unveils four all-new models – the NK200, NK190, NK170, and NK150 – designed to deliver a precision tiering strategy that lets customers match machine capability to job scale, from heavy mining haul roads to municipal maintenance and agricultural land forming.

Instead of a one-size-fits-all approach, the NK series provides a clear performance ladder. Operating weights range from 13,000 kg to 16,500 kg, and maximum drawbar pull spans 82 kN to 110 kN. This granular segmentation enables contractors, fleet managers, and government agencies to avoid over-investing in oversized machines or under-specifying for demanding terrains – a direct response to rising fuel and maintenance costs worldwide.

Heavy-Duty Flagship: NK200 – Built for High-Output Earthmoving

Topping the range, the NK200 is engineered for large-scale road construction, highway rehabilitation, and mine haul-road upkeep. Its SDEC C6121 diesel engine delivers 162 kW of rated power, mated to a ZF 6WG200 electro-hydraulic transmission that ensures smooth power delivery under extreme loads.

Operating weight: 16,500 kg

Maximum drawbar pull: 110 kN

Blade length: 3,962 mm (13 ft)

Braking system: REXROTH fully-hydraulic with high-load automatic lock/unlock anti-slip differential

Ideal for: heavy grading, deep cuts, and continuous high-torque operations in mining and interstate projects.

Mid-Range Workhorses: NK190 & NK170 – Versatility for Mixed Fleets

The NK190 shares the same 162 kW power output as the flagship but at a lighter 15,500 kg curb weight, making it a fuel-efficient alternative for regional roadworks and site development. It employs a Hang Chi (Advance) 6WG180 transmission (6 forward / 3 reverse gears), offering a balanced trade-off between power and agility.

Stepping down, the NK170 provides 129 kW power at 14,500 kg operating weight and 90 kN drawbar pull. This model excels in medium-scale land leveling, airport runway maintenance, and large agricultural field drainage projects where precision and moderate power are prioritized.

Both models retain the same high-quality cabin and hydraulic features as the top-tier unit, ensuring operator comfort and control consistency across the fleet.

Entry-Level Economy: NK150 – Compact Grading for Urban & Small-Site Jobs

Completing the lineup, the NK150 is powered by a Weichai Deutz engine rated at 115 kW, with a 13,000 kg operating weight and 82 kN drawbar pull. Its shorter 3,350 mm (11 ft) blade makes it exceptionally maneuverable in congested municipal zones, residential subdivision grading, and small-farm irrigation ditch construction.

Despite its entry-level positioning, the NK150 does not compromise on core durability – it shares the same fully sealed box-structure frame and single-lever joystick controls found on larger siblings.

At-a-Glance Comparison Table (All Models)

Model Engine Power (kW) Operating Weight (kg) Drawbar Pull (kN) Blade Length Primary Applications

NK200 162 (SDEC) 16,500 110 3,962 mm Heavy road / mining haul

NK190 162 (SDEC) 15,500 110 (est.)* 3,962 mm Regional highways / sites

NK170 129 (SDEC) 14,500 90 3,962 mm Land leveling / agriculture

NK150 115 (Weichai) 13,000 82 3,350 mm Municipal / small projects

*NK190 pull force equivalent to NK200 due to same powertrain but lighter weight – actual field performance varies with tire and ground conditions.

Common DNA – Built for Operator Productivity and Low Total Cost

Across the NK series, NEW SKY has standardized several high-value features that reduce training time and downtime:

ROPS/FOPS-certified, fully sealed cabins with heating, A/C, and MP3 connectivity – ensuring year-round comfort in extreme climates (from -20°C to +45°C).

Open-center hydraulic systems with adjustable blade response: NK200 uses imported main pumps/valves; NK190/170/150 feature Husco control valves for reliable, precise metering.

Single-lever joystick control – operators can master grading within hours, reducing fatigue and boosting daily output.

High-load automatic lock/unlock anti-slip differential – standard on all models, ensuring traction on slippery or uneven surfaces.

360° blade circle rotation with a 610 mm chord length, enabling complex angle adjustments without leaving the cab.

Fully sealed box-type frame – resistant to torsional stress and compatible with a wide range of attachments (snow plows, scarifiers, etc.).
