Thank you for sharing your experience. We are sorry to hear about the issue with the self-propel system on your 80V mower. Based on what you have described, the mower shutting down when the self-propel lever is engaged can sometimes be related to a safety interlock, battery connection, or a temporary overload condition. As a first step, we recommend removing the batteries, inspecting the terminals for any dirt or debris, and reinstalling them firmly to ensure a secure connection. It is also helpful to check that the handle and safety bail are fully engaged, as partial engagement can interrupt operation. Make sure the wheels and drive system are free of grass buildup or obstructions, and try operating the mower on a flat surface with a slightly higher deck height to reduce load. If the issue persists, try alternating between the batteries to see if one may be underperforming, and ensure both are fully charged and cooled before use. For additional troubleshooting guidance and maintenance tips, we encourage visiting the Greenworks YouTube channel, where you can find helpful videos on lawn mower operations and care. If you continue to experience issues, we recommend reaching out to our Customer Success team for further assistance, they can help diagnose the problem and provide next steps.

Hello George Scott,
Thank you for sharing your feedback. We understand your frustration. Mowing the grass in the Florida heat is tough enough without having to make multiple passes over thick, coarse turf like St. Augustine grass. We hear you, and we appreciate both your support for electric mowers and your honest take on performance.
St. Augustine grass is notoriously dense and broad-leafed, which can present a unique challenge for lawn mower suction and cut quality. If you are open to giving it another shot, here are a few troubleshooting tips that can help improve performance and cut quality:
1. Stagger your cutting height: Avoid cutting off more than 1/3 of the grass blade at a time. For St. Augustine, keeping the deck set higher (typically 3" to 4") reduces the load on the motor and helps maintain optimal blade speed/lift.
2. Inspect blade sharpness and rotation: Ensure the mower blade is sharp and installed in the correct orientation. A dull blade or incorrect blade position significantly degrades cut quality on thick turf.
3. Mow when completely dry: St. Augustine holds a lot of moisture. Mowing late in the afternoon when the lawn is fully dry prevents clumping and improves air suction under the deck.
4. Keep the under-deck clean: Grass buildup under the deck chokes airflow, which is critical for pulling grass blades upright before cutting.

We want to make sure you get the performance you paid for.
