AERA-vator Shaft
Vibratory aeration
This is the shaft that defines the machine. As the unit moves, the tines vibrate and fracture soil compaction beneath the surface — relieving the rootzone without pulling cores or tearing the canopy. It is the everyday aeration tool for surfaces that cannot afford downtime, and with the optional seed box it meters cool- and warm-season grass seed while it works.
