Greenworks 22 in. 60V Cordless Walk-Behind String Trimmer, Battery and Charger Included

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.

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.

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.
