ABSTRACT:
An aerator plug-core cleaning system for ground surface collection of turf cores extracted from a turf core-aerating apparatus. The core-cleaning system comprises a core-cleaner that primarily attaches to either a walk-behind or tractor pulled aerator machine. The core-cleaner entraps and pushes the extracted cores along behind the core-aeration machine until being lifted in about a vertical manner by secondary attachment to a rear raise-able portion of the core-aeration machine at which point the cores are left in a pile for disposal.
