The Bullseye RotaQuake™ 630 is an aerator that decompacts the soil using a set of rotating steel blades. As these blades cut cleanly through the soil, they create a wave action that shatters compacted areas and opens up the subsoil. The RotaQuake™ can work at depths up to 10” (25.4 cm) with minimal to no surface disruption to keep your turf ready for play. The rear roller smooths surface behind rotating blades and the integrated legs make unhooking and storage easy.
