When digging is complete, finish the job by powering into the soil and packing it down with the trench compactor attachment. A vibratory shaker box delivers optimal compaction across a wide range of soil types. Designed to work most efficiently in trenches 4 to 12 inches wide and up to 4 feet deep, it compresses soil evenly for a clean, tightly packed trench. The ideal finishing solution for professional trenching applications.
