Bottom Line

This Greenworks 40V cordless mower has proved to be highly effective and convenient during its initial use, especially on tall, wet grass and uneven terrain. It’s great for small to medium lawns with easy operation, low noise, and eco-friendly features. However, potential buyers should be cautious about the battery’s longevity and the company's support, as multiple reviews report significant degradation and unresponsiveness. If you’re considering extended or heavy-duty lawn care, exploring models with longer-lasting batteries or a more responsive customer service team might be wise.
