Upgraded Blade Kit: This Upgraded Weeder Replacement Head can currently only be used with plastic blades, not with trimmer shafts. This product kit will be sent with 10 plastic blades. Plastic blades have the advantage of being more durable than trimmer wire while cutting faster, but they are also consumable. The trimmer head we changed to nylon material and the blades are thickened, which is 2 times the thickness of the blades in the market, more durable.
EASY INSTALLATION: Simply push this trimmer head into the stringer socket and it will automatically lock into place with the help of the side button, and no adapter is required.
BEST USE: Avoid using this accessory on edging, brick fencing, chain link fencing or wood fencing, stay away from rocks or other hardscapes as they break easily. When cutting vertically, it is recommended that you replace the trimmer blades with trimmer spools.
Quality Assurance:If you have any quality problems, please feel free to contact us, we will provide appropriate solutions within 24 hours.
