Utilizing the Imants Rotoknife and Imants Shockwave, RNA Turf is able to relieve surface compaction, improve aeration, reduce thatch accumulation, and fracture the soil at varying depths. The pto-less Imants Rotoknife uses its robust build to force a wide arrangement of discs into the soil to meet your desired depths and spacing at increased speeds with minimum surface disruption. The Imants Shockwave is a powerful linear decompactor that fractures the soil from 4.5” to 10” in depth even in difficult soils with minimal surface disruption.
