Hello KD985.
We are sorry to hear about your experience and understand how frustrating it can be when the self-propelled function is no longer operating as expected. Based on what you described, there are a few areas that may be helpful to check. Ensuring the drive control cable is properly connected and has not become loose or stretched over time can help, as this directly affects engagement of the self-propel system. It may also be worth inspecting the rear wheels and drive gears for any debris buildup or obstruction, as well as confirming that the height adjustment is even on both sides, since uneven settings can impact traction and drive performance. Additionally, checking that the battery is fully charged and properly seated can help rule out power-related inconsistencies.
We understand your concerns regarding parts availability and documentation, and your feedback is important as it helps identify opportunities for improvement. If the issue is not resolved after these checks, we recommend contacting our support team directly so they can further assist with troubleshooting and review available service options with you. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.

Thank you for sharing your experience. We are glad to hear you are happy with the mower’s overall performance, but we understand how frustrating the runtime has been. Battery runtime on the 80V platform can vary quite a bit depending on usage conditions, and using the self-propelled drive does place additional demand on the batteries. Factors like grass thickness, cutting height (especially lower settings), mowing speed, and terrain can all impact how long the batteries last. To help improve runtime, you might try mowing at a slightly higher deck height, using the self-propel feature only when needed, and maintaining a steady, moderate walking pace. Keeping the blade sharp and mowing more frequently to avoid heavier cuts can also make a noticeable difference. It is also worth noting that a 2.0Ah battery will provide shorter runtime compared to a 4.0Ah, so performance may feel limited when relying on smaller-capacity batteries, especially with self-propel engaged. For larger areas or extended sessions, higher-capacity batteries (such as 4.0Ah or above) are typically better suited.
If you continue to see a reduced runtime under normal mowing conditions, it may be worth reaching out to Greenworks for further evaluation. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.
