Thank you for sharing your experience. We are sorry to hear that your 60V CrossoverZ mower is displaying a C9 error code and that you have been unable to charge the unit before ever having the opportunity to use it. We understand how frustrating and disappointing that can be with a new purchase. There are a few troubleshooting steps that may help resolve the issue. First, inspect the battery cable harness and any auxiliary communication wires running between the charger, charging port, and battery compartment to ensure all connections are secure and free of dirt, debris, or corrosion. You can also perform a hard reset by disconnecting all batteries and the charger from the mower, waiting 2 to 3 minutes to allow the internal system to fully discharge, and then reconnecting everything before attempting to charge again. If the C9 error persists after these steps, the charger or mower's internal power management components may require further evaluation. We recommend visiting the Greenworks YouTube channel for additional setup and troubleshooting resources. If you still need assistance, please contact our Customer Success team through the online chat feature on the Greenworks Tools website or by calling 1-888-909-6757 (1-888-90WORKS). Our team will be happy to help diagnose the issue and determine the best solution under warranty if needed.

Thank you for sharing your experience. We are sorry to hear that this mower did not meet your expectations, especially after having a positive experience with your previous Greenworks mower. The battery compartment doors should close securely during operation, so the behavior you described is not expected. For the battery door, we recommend removing the battery and carefully inspecting both the battery compartment and door latch area for any debris, packaging material, or obstructions that could prevent proper closure. Ensure the battery is fully inserted and clicks securely into place, as a partially seated battery can sometimes prevent the door from latching correctly. It may also be helpful to compare both battery compartments to determine whether the issue is related to the door itself, the latch mechanism, or battery fitment. If the door still does not close properly after these checks, the unit may require further evaluation. Regarding cutting performance, results can vary depending on grass type, grass height, moisture levels, and mowing settings. For thicker Southern grasses, we recommend verifying that the blades are sharp, selecting an appropriate cutting height, and avoiding removing more than one-third of the grass height in a single pass. If you would like additional troubleshooting assistance, the Greenworks YouTube channel offers helpful setup, operation, and maintenance videos. You can also contact our Customer Success team through the online chat feature on the Greenworks Tools website or by calling 1-888-909-6757. They will be happy to help review the battery door concern and mower performance with you. We appreciate your feedback and will share your comments with our team.

Hello Sam61. Thank you for taking the time to share your detailed experience. We are glad to hear that you have been pleased with the mower's power and maneuverability. We understand that runtime is an important consideration, especially for larger properties. Battery runtime can vary based on grass type, grass height, moisture levels, terrain, and overall mowing conditions. Thicker or damp grass and letting the lawn grow longer between cuts can increase power demand and reduce runtime compared to ideal testing conditions. To help maximize runtime, we recommend mowing regularly, avoiding wet grass when possible, ensuring the blade remains sharp, and using a higher cutting height when conditions are more challenging. For larger lawns or more demanding conditions, having an additional battery available can help extend mowing time and improve convenience. We appreciate your feedback regarding battery capacity and your suggestions. If you would like additional tips on optimizing performance, please visit the Greenworks YouTube channel.

Hello Sam61. Thank you for sharing your experience. We are glad to hear that you have been pleased with the mower's power and maneuverability. Battery-powered mowers can experience shorter runtime when cutting thicker, taller, or damp grass, as the motor works harder to maintain cutting performance. To help maximize runtime, we recommend mowing regularly, avoiding wet grass when possible, and keeping the blade sharp. We appreciate your feedback regarding battery capacity for larger lawns.
