According to Wacker Neuson, the company has reengineered its RD7 walk-behind tandem rollers for easier operation and service, as well as improved compaction performance. The new models, designed for compacting a range of soil types and asphalt, are now available with a choice of diesel or gasoline engines.
The RD7He, powered by an 8.2-horsepower Hatz diesel engine with electric start, has an operating weight of 1,624 pounds. The RD7A, with an operating weight of 1,512 pounds, uses a 9.7 horsepower Honda gasoline engine. Both models have a drum width of 25.6 inches and feature a high centrifugal-force setting (4,998 pounds) and a low setting (2,935 pounds). Hydrostatically driven, the new models feature hydraulic hoses and cables that are protected from damage.
The RD7 Series features a compact design with dual, smooth, beveled-edge drums designed for tight side clearance on both sides of the machine. A new patent-pending handle design provides multiple gripping points for easier control and turning, and a center handle allows the operator fine control while finishing asphalt. In addition, RD7 models have a shorter wheelbase and reduced overall weight to facilitate turning.
Other features that enhance operator comfort and convenience, says Wacker Neuson, include an easy-to-reach throttle and low/high exciter-force controls located on the shock-mounted, low-vibration handle. The handle also features a unique foot-operated handle lock that allows for easy tilting of the handle for storage.
A large water tank with an easy-access cap and a quick-view water-level indicator allows longer running time between refills, and an open-frame design allows fast cleaning with a pressure washer, says the company.
