The YH650 Walk Behind Double Drum Roller is a compact compaction machine powered by a Greaves 1510 diesel engine (10 HP). Designed for efficient soil and asphalt compaction, it delivers a centrifugal force of 20 kN with a vibration frequency of 75 Hz. With a robust 550 kg operating weight, 35 L water tank, and hydraulic oil tank of 6 L, it ensures consistent performance. Its forward and reverse walking capability (0–4 km/h), combined with a 30% gradeability, makes it suitable for challenging work environments. Compact dimensions (1350×940×1220 mm) and a 600 mm drum diameter allow easy operation in confined areas.
