Thank you for sharing your feedback with us. We are glad to hear you like the design and performance of the tool, though we understand your concern regarding runtime and charge time. Battery runtime can vary based on the specific tool model, grass height, and workload conditions. For larger yards or demanding tasks, upgrading to a higher-amp hour (Ah) battery, such as a 4.0Ah or 5.0Ah unit, can provide significantly longer runtimes and reduced downtime. We appreciate your recommendation and feedback, and if you ever need assistance finding compatible higher-capacity batteries, please feel free to reach out to our support team! They can be reached either using the online chat function, on Greenworks Tools website, or by calling 1-888-909-6757.

Thank you for taking the time to share your detailed feedback on the 60V 22" Wheeled String Trimmer! We are thrilled to hear that the trimmer's balance, guard coverage, and string setup have made clearing rocky, uneven terrain much safer and cleaner for you. We also sincerely appreciate your candid notes regarding the battery switching behavior and the broken bump guard, as we want your machine operating smoothly and reliably. Regarding the battery dual-port operation, the system is designed to draw from one battery until it reaches a low-voltage threshold before automatically transferring to the second. A brief pause in trigger engagement is often necessary to allow the internal control board to recognize the switch, but you should not need to physically remove a battery. To help ensure seamless automatic switching, verify that both battery packs are fully latched into place and that the terminal contacts inside the bay remain clean and clear of dust or fine debris. For the broken bump guard, we strongly caution against attempting to weld components onto the trimmer head assembly, as DIY welding can throw off shaft balance, generate dangerous metal fatigue, or impact warranty coverage. For visual guides on general tool maintenance, battery port care, and operating tips, please feel free to visit the Greenworks YouTube Channel. We want to help get your machine properly equipped so you don't have to deal with grass wrapping around the shaft, so please contact our Customer Success Team directly so we can look into part availability for your specific model, review your warranty options, and assist you with securing a replacement guard assembly. They can be reached either using the online chat function, on Greenworks Tools website, or by calling 1-888-909-6757.

Thank you for sharing your feedback. We are glad to hear you appreciate the increased line capacity, but we understand your concerns regarding the rotation direction and how it affects usability. The rotation direction on this model is part of the design and may differ from previous units. Cutting performance and debris direction can vary depending on trimming angle, positioning, and technique. For improved control and to help direct debris away from you, we recommend adjusting your stance and trimming from right to left when possible, as well as using the guard to help deflect clippings. We understand that changes in design can take some getting used to, and we appreciate you sharing your experience. If you ever have specific questions or concerns about our products, contact Greenworks via chat on our website, call us at 1-888-909-6757 (1-888-90WORKS) or refer to the FAQ ask section of the tool or ask us a question, anytime.

We appreciate your feedback and are glad to hear that you are enjoying the smooth power, solid construction, and reliable battery life of your 60V 16" Direct Drive String Trimmer. Performing vertical lawn edging with a straight-shaft trimmer can feel a bit awkward initially, as the head angle requires adjusting your body posture and grip compared to standard horizontal trimming. To make edging smoother and more comfortable, try rotating the entire trimmer housing 90 degrees so the cutting head is perpendicular to the ground, then adjust the position of your front auxiliary handle along the shaft to create a comfortable leverage pivot. Supporting the shaft against your hip or forearm while maintaining a balanced, walking stance helps guide the cutting line evenly along sidewalk and driveway borders without straining your arms or wrist. For visual demonstrations on trimming techniques, handle adjustments, and clean edging practices, we invite you to check out the tutorial videos on the Greenworks YouTube channel. If you ever need additional support or tips on adjusting your trimmer for specific tasks, our Customer Success team is always happy to assist. They can be reached either using the online chat function, on Greenworks Tools website, or by calling 1-888-909-6757.

Hello Mike4. Thank you for your feedback. We are glad to hear the trimmer head is performing well for you. We understand your concern regarding the bump knob and the need to replace the entire trimmer head when that component wears out. As a workaround, we recommend checking the bump knob regularly for wear, cleaning away any debris that may affect its operation, and making sure the trimmer line is loaded correctly to reduce unnecessary strain on the part. If the bump knob becomes worn or damaged, replacing the full trimmer head may be the most reliable option at this time. Our success team can also help confirm whether there are any compatible replacement parts or alternative solutions for your specific model. Your feedback is valuable, as the bump knob is a high-contact wear item, and we recognize the benefit of offering it as a separate replacement part. We appreciate you taking the time to share your experience. If you require any additional support or have questions regarding a product, we recommend trying our Q&A section on products' page or Chat with us directly on our website or call 1-888-909-6757. We are here to help.

Hello Miker1212. We are sorry to hear about the difficulty you are experiencing with restringing the trimmer, and we appreciate your continued support of Greenworks. It sounds like your unit may be equipped with an S-Type trimmer head, which can require a slightly different technique compared to older styles. To help make the process easier, we recommend ensuring you are using the correct line diameter specified for your model and cutting a straight, clean edge on the line before inserting it. Try gently rotating the head while feeding the line through, as this can help align the internal channel and allow the line to pass through more smoothly. If resistance continues, check for any debris or buildup inside the eyelets that could be obstructing the path. For a step-by-step visual guide, you can reference the following video which demonstrates how to properly load line on this style of head: https://www.youtube.com/watch?v=-3UtaGkO0vI&t=53s If the issue persists, our success team would be happy to take a closer look and assist further.

Hello MGlen. Thank you for your feedback. We understand how frustrating it can be when string feed performance is inconsistent, especially during edging where steady line advancement is important. For the 60V 16" Gen2 String Trimmer (SKU 2122802), frequent line breakage and the need for multiple bumps can often be related to line type, installation, or cutting conditions. We recommend ensuring the line is properly loaded and evenly wound in the head without overlap, as uneven winding can restrict smooth feed. If you are still using the preloaded line, you may want to try a high-quality 0.080" or 0.095" line, as thicker or more durable line can reduce breakage depending on the application. Also, avoid cutting directly against hard surfaces like concrete or fencing, as this can cause rapid wear and snapping. When bump feeding, a firm tap on a hard surface (rather than grass) typically provides more consistent line advancement. You may also find it helpful to review Greenworks instructional videos on the Greenworks Tools YouTube channel for proper line loading and trimmer head operation. If the issue continues after trying these steps, we recommend reaching back out to Greenworks support so they can review your case further and assist with next steps or potential service options. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.

Hello LC-John. We appreciate you sharing this detailed feedback, it is helpful for others considering this unit. The 22" wheeled trimmer is designed to perform well in lighter-duty conditions like dry grass and standard weeds, but as you have noted, components such as the spindle/mower ball (ground contact point) can experience accelerated wear in abrasive environments like rocky soil. Frequent contact with hard surfaces increases friction and can shorten the lifespan of that part. To help extend durability, we recommend minimizing direct ground pressure when possible, periodically inspecting the cap for wear, and replacing it before excessive degradation affects performance. Availability of high-wear replacement parts can vary, so it may be beneficial to check periodically or connect with Greenworks success for assistance in locating compatible replacements or confirming part numbers.
