Hello Razzy.
Thank you for taking the time to share such a detailed review after five years of use. We value that level of insight. We are glad to hear the mower has held up well and continues to deliver on durability and convenience, especially with battery longevity over time. We understand your concerns regarding cut quality, suction, and leaf pickup, and there are a few factors that can influence performance in these areas. Over time, blades can become dull or worn, which reduces lift and overall cutting efficiency, so sharpening or replacing them, and ensuring they are installed correctly, can make a noticeable difference. Keeping the underside of the deck clean is also important, as buildup can disrupt airflow and impact both cutting and mulching performance. Additionally, battery condition plays a role in maintaining optimal blade speed, so using fully charged or newer batteries can help improve consistency, particularly when using higher power modes like Turbo. For tougher conditions such as longer grass or leaf pickup in the fall, adjusting the cutting height or making multiple passes can also help improve results. We appreciate your feedback regarding blade design and airflow, and insights like yours are shared with our product team as we continue to refine and improve future models. If you would like, our team would be happy to work with you directly to review your setup and help optimize performance, please do not hesitate to reach out to us on either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.
