Hello Mark54. We appreciate you taking the time to share your detailed feedback. We are sorry to hear that your experience with the mower has been frustrating. The issues you have described with cut quality, maneuverability, and battery runtime are not what we want our customers to experience. Runtime can vary and depend on a few factors, including but not limited to using self-propelled, self-propelled mowers do use more batteries than standard push mowers as more power is being demanded from the battery to run the blades and the wheels. Grass texture and consistency. Cutting height and lawn size, when grass is not too thick and well maintained under 4 inches. For added runtime, we recommend purchasing an additional battery, Greenworks 80V batteries are interchangeable with 80V units, the higher the ampere-hour (AH) rating is on the battery, the longer the run time will be in comparison to a lower ampere-hour battery. The self-propelled feature is not usable in reverse. They are designed to lock when pulled back to prevent damage to the drive belt. If you are using the self-propelled feature, the mower will attempt to move forward and will be difficult to move backwards. You would have to release the self-propelled lever to pull the mower backwards while still holding onto the start lever. We hope this information helps you understand our product better and perhaps encourages you to give it a second chance!
