The sand weight tanks are two optional containers that give the core aerator an extra pressure boost when working with highly compacted soil.
The CA2048E Core Aerator holds up to 70.8 kg (156 lb) of sand, the CA2060E Core Aerator holds up to 113.4 kg (250 lb) of sand, and the CA2072E Core Aerator holds up to 320 lb of sand. This ensures that hard turf is completely aerated the first time.
The CA20E Series Economy-Duty Core Aerators has six aerating spoons per hub that penetrate 11.4 cm (4.5 in.) below heavy thatch and tough soils. This greatly breaks up soil compaction and revitalizes lawns.
