I love this trimmer and I already have another one. However, this one a different head on it and it is extremely difficult to get the string to pass all the way through. When you're trying to restring it. I can only get it to go in from one side and it takes a lot of work and patience to get it to finally slide through. My older one does not have that problem but the head is different on it
Pros: Cost-Saver, Easy to Use, Durable
I would recommend this to a friend!

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.
