Ideal for work on granular, cohesive, and mixed soils, the BPR45/55D reversible plate compactor offers an 8.9-hp air-cooled diesel engine that delivers nearly 50% more power than its predecessor. Increased power, combined with new base-plate geometry and optimized positioning of the center of gravity, results in an 89 feet-per-minute working speed, 10,125-pound centrifugal force, and 35% gradeability. Plus, maximum vibration frequency is now 4200 vpm. Bomag Americas, 800-782-6624,
