R440 Rammer Series

The R420, R421 & R440 Series Rammer are ideally suited for the compaction of granular, mixed, and cohesive soils in confined areas. A mainstay in contractor and municipal fleets, the R420 & R440 offer highly productive percussion rammers at less than 128 or 142 lbs. respectively. The contoured fuel tank provides the largest fuel capacity in its class and effectively baffles engine noise. Power is supplied by Honda engines.
