Our hollow tine lawn aerator is an essential garden tool designed to prevent lawn compaction, promote healthier garden grass in well-trodden areas, and improve general lawn health ready for seeding. The coring tines extract soil plugs to promote grass root access to nutrients, moisture and oxygen.This garden aerator features five evenly spaced tines with strong welds, designed for large surface area aeration. Each tine aerates deep into soil to help release trapped CO2 around roots, enhancing your garden's overall health.
