The Greenworks 40V 2-in-1 dethatcher and scarifier is ideal for revitalizing and reviving tired lawns. This tool, manufactured by Greenworks, is designed for medium-sized yards. It allows you to easily remove thatch and aerate the soil, encouraging new growth. Use the sprung de-thatcher attachment to remove thatch, dead grass, and debris. For more thorough aeration, switch to the heavier scarifier attachment. The grooves created are perfect for overseeding, providing ideal spots for new seed to germinate. This unit features a brushless motor, which reduces vibrations and requires minimal maintenance. Adjust the height of the unit with its 5-position adjustable height range, offering a working depth of 35mm-114mm.
