Thank you for sharing your feedback. We are sorry to hear that the T-Type Head Assembly was not compatible with your trimmer as expected. We understand how frustrating it can be when a replacement part does not fit the intended model. If you have not already done so, please contact the Greenworks Customer Success team with your trimmer model number so we can review the compatibility information and help identify the correct replacement part. They can be reached either using the online chat function, on Greenworks Tools website, or by calling 1-888-909-6757. We appreciate your feedback and the opportunity to assist.

Thank you for being a loyal Greenworks customer and investing in our 80V system. We completely understand how frustrating it is when a key part like a trimmer head is temporarily out of stock and holds up your work. Depending on your trimmer model, you may be able to rewind standard 0.080" or 0.095" trimmer line directly onto your existing spool, or clear any debris caught in the head mechanism if it feels stuck or jammed. For visual, step-by-step guidance on reloading trimmer line and maintaining your equipment, we invite you to check out the official Greenworks YouTube channel. If the entire head assembly needs replacement and shows out of stock online, please click the "Notify Me" button on the product page to get an immediate email alert the moment inventory is replenished. Should you need direct assistance identifying a compatible alternative head or checking stock updates, our Customer Success Team is ready to help at 1-888-909-6757 or through our online support portal.
