Hello greenwashed99.
We are sorry to hear you are unhappy with the mower's protection features. The mower likely enters "turbo" mode automatically due to an overcurrent protection system that kicks in when the battery is being heavily stressed, possibly by thick grass or uneven terrain. This is a safety mechanism to prevent damage to the battery and motor.
To address this, we recommend exploring a few troubleshooting steps to potentially improve your battery's performance.
1. Check Grass and Terrain. Make sure you are not mowing through excessively thick or long grass, or areas with a lot of debris. Try adjusting the cutting height or moving through areas in shorter passes if possible.
2. Self-Propelled Engagement. If you are using the self-propelled feature, try engaging it more gradually and with a lighter touch. Excessive strain on the self-propelled mechanism can also trigger the overcurrent protection.
3. Battery Condition. Ensure your batteries are fully charged and in good condition. Worn batteries may struggle to provide the necessary power, leading to more frequent activation of the overcurrent protection.
Yes, the batteries will require time to cool before charging. The amount of time that the battery requires to cool will vary depending on how much they have heated up while in use.
The outdoor temperature can affect battery run time. If the unit is used in extreme heat, this causes the battery to overheat and deplete. We apologize for any inconvenience that this might cause.
If you have tried these steps and the problem persists, we recommend contacting our customer support team for assistance with properly submitting a warranty claim. They can be reached either using the online chat function, on Greenworks Tools page, accessible by clicking “Chat with an Expert” in the bottom corner of your screen, Chat with a Live Agent I Monday - Friday: 9:30am – 5pm EST or by calling 1-888-909-6757 between 9AM and 7PM EST, M-F.

Thank you for sharing your experience with us. We’re sorry to hear the run time hasn’t met your needs. Several factors can affect battery life—dense or tall grass, hilly terrain, or grass over 4 inches all require more power and can shorten run time.

For best results, we recommend raising the cutting height and trimming no more than one-third of the grass length at a time, then waiting a couple of days before cutting again. Mowing when the grass is dry and walking at a steady pace will also help the blade work more efficiently. As your lawn becomes regularly maintained, you should see both cut quality and run time improve.
