Rammer - R442H

Weight - 150 lbs

The R442H Rammer is ideally suited for the compaction of granular, mixed and cohesive soils in confined areas. A mainstay in contractor and municipal fleets, the R442H is a highly productive percussion rammer at 150 lbs. The contoured fuel tank provides the largest fuel capacity in its class and effectively baffles engine noise. Power is supplied by a Honda engine. Model R442 delivers approximately 25% more compaction force and is recommended for heavy clay soils.
