Pinpoint accuracy on any contour

The STEINER® Core Aerator attachment with 3/4-Inch core tines assemblies can core up to 3 1/2-inches deep, even on the most challenging contours. With the option to add additional weight for better ground penetration in difficult soil conditions, the Core Aerator’s precise, quality coring is proven to reduce compaction and improve overall turf health.
