The 25 Series Core Aerators are designed to 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. These Aerators utilize replaceable case hardened closed spoons mounted on weighted rotating discs, and the spoons pull cores up to 3" in length from the soil profile every 7" of forward travel.Pulled cores are deposited on the surface for subsequent drying, pulverization, or removal. In order to achieve maximum penetration the CA2572 offer optional poly water tanks that fit in the top mounted weight trays. When filled with water these tanks provide significantly increased down pressure on the spoons. When your turf begins to suffer the effects of compaction and wear, such as shallow root zones, thatch build-up, worn pathways, hard-pack soil, poor surface percolation, or water stands, a Land Pride 25 Series Core Aerator will provide immediate seasonal relief.
