The SDLG G9165F motor grader is a mid-size grader powered by a ~172 HP (129 kW) Weichai diesel engine, with an operating weight of about 14–15 tons, designed for stable and efficient roadwork; it features a 3.6–3.9 m moldboard (blade) for wide, precise grading, a 6×4 drive system with multiple forward and reverse gears for good traction and control, and can reach speeds of around 40 km/h, making it suitable for both heavy-duty grading and smooth finishing while remaining fuel-efficient and easy to maintain.
