EGO’s Multi-Head system is brilliant, and the cultivator attachment is one of its strongest entries. Because it uses the massive 56V powerhead, it has a level of "grunt" that other battery cultivators simply can't match.
I highly recommend pairing it with the carbon fiber powerhead, it keeps the overall weight down and makes it much easier to control. It sets up in seconds and tills surprisingly deep for an attachment. For anyone who already owns the EGO string trimmer or blower with the powerhead, this is an absolute no-brainer add-on.
Things to Consider: It’s an attachment, so it’s long (the length of a trimmer). This can make it a bit awkward in very small, confined garden beds. But in terms of pure power-per-pound, it’s the best battery cultivator on the market.
