Top 100: Four-Cycle Convenience
Designed with a four-stroke-cycle, 2.4-hp Robin engine, M-B-W's R420 rammer provides added convenience to operating and transporting rammers. The new tool is ideal, says the manufacturer, for use in cohesive and mixed soils, providing compaction forces up to 3,000 pounds and percussion rates up to 750 bpm. Using a narrow tamping shoe, the R420 fits into tight spaces, and its light weight makes it easy to maneuver and transport. Estimated price: $3,150.
