The Land Pride CA1572 Core Aerators relieve soil compaction and allow air circulation in grassy surfaces such as lawns, soccer fields, football fields, baseball fields, municipal parks and golf course fairways. They utilize replaceable hardened spring steel spoons mounted on rotating discs. Pulled cores are deposited on the surface for subsequent drying, pulverization or removal. Weight can be added to the weight tray to help achieve maximum spoon penetration. When your turf begins to suffer the effects of compaction and wear, such as shallow root zones, thatch build-up, worn pathways, compacted soil, poor surface percolation, or water stands, a Land Pride CA15 Series Core Aerator will provide immediate seasonal relief.
