The EGO cultivator attachment is a great addition to the EGO POWER Multi-Head System. The heavy-duty steel tines are adjustable from 8 to 9. 5 inches. This allows for easy tilling between shrubs, bushes, trees and flowers. A variable speed trigger allows you to power through the hard ground or dial it back for the softer soil. EGO attachments are designed specifically for your EGO POWER Power Head (PH1400) and offer the highest quality and performance.
