New heads from Toro are $45. I bought this EZ Lock head, and had it installed in 10 minutes. Most of that time was spent using a tap to chase the shaft threads on my trimmer , which were a little messed up. The EZ Lock comes with an assortment of bolts and nuts to fit many trimmer shafts, and my Toro uses the 5/16x18 short bolt that came in the kit. Once installed, I loaded the two lines, which is as simple as it gets. Push the line in, pull, and it locks. To release, flip the locking lever over and pull the line out. I started with some easy trimming, normal lawn grass trimming. Works great. Now for the big test, trimming the grass and weeds on the back of my range backstop. It hasn't been touched all summer. Tall stuff, and an assortment of grass and woody plants. It ate right into them, and did well until the long weeds wrapped themselves around the shaft. I had to stop every minute or so to cut off those weeds. This is because this trimmer head sits down further from the end of the curved shaft, allowing the weeds to wrap around. The original head did the same thing, just not quite as bad. That's just how it is when cutting tall grass and weeds. Overall, I like this EZ Lock trimmer head. Easy to install, works well, and appears to be well made. Half the price of a Toro replacement head, and easier to load line and use. If it continues to perform, I'm happy. Review: I'm loving it now! - A big thanks to reviewer, Randy, for providing a detailed explanation how to adapt to a Kobalt trimmer. I went to Lowes and found the specific metric sized nut as directed in his post. Didn't have a grinder and the Dremel was ineffective, so used a long, heavy file and kept working each of the six sides until it finally slipped into the nut cut-out opening. In retrospect, the hardest part was getting the old bump knob off as everything turned together. What may have worked was a squirt of WD-40 and then a simple pry up and it came off easy. Really enjoying how this item is now twice as effective and how the stress of never knowing if the line will advance has been eliminated. ## Features - EZ Lock Replacement Head: For highly durable, trimming, edging and weed eating tasks, the easy-to-install EZ Lock fixed line trimmer head replacement gets the job done; Ruggedly built from high-quality materials; Fits a variety of line sizes - Easy To Install: Remove the old head and thread on the EZ Lock with included hardware and adapter if needed; Uses pre-cut line strips to save you the time and hassle of spooling line, without the need to open the head - Universal Fit: Fits 80/1000-inch to 105/1000-inch diameter line and is compatible with nearly all brands of gas and cordless string trimmers including Echo, Stihl, Husqvarna, Redmax, Ryobi, Cub Cadet, Weed Eater, Poulan, MTD and more - Professional Grade: Find the right replacement parts for your trimmer or weed whacker; Our brand-compatible trimmer line, fixed line, bump feed, hybrid and bladed heads are built to the high standards and demanding needs of professional landscapers - Weed Warrior: We manufacture high quality universal fit weed wacker trimmer line, heads, and accessories built for extreme toughness through years of detailed research and development both in the lab in in the field ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00O7BZURQ | | Assembly Required | No | | Best Sellers Rank | #14,679 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #64 in String Trimmer Replacement Parts | | Brand | WEED WARRIOR | | Brand Name | WEED WARRIOR | | Color | black | | Customer Reviews | 4.3 out of 5 stars 2,216 Reviews | | Cutting Width | 6.44 Inches | | Cutting width | 6.44 Inches | | Global Trade Identification Number | 00015221167418 | | Included Components | trimmer head, universal fit hardware kit | | Is Product Cordless | Yes | | Item Dimensions L x W | 6.5"L x 3.5"W | | Item Type Name | Universal Fit Trimmer Head | | Manufacturer | Weed Warrior | | Manufacturer Part Number | 16741 | | Model Number | 16965 | | Number of Items | 1 | | Power Source | gasoline-powered | | Product Dimensions | 6.5"L x 3.5"W | | Recommended Uses For Product | Trimming, edging, and weed eating tasks | | Required Assembly | No | | Size | Original version | | Style Name | Replacement Head | | UPC | 015221167418 | ## Product Details - **Brand:** WEED WARRIOR - **Power Source:** gasoline-powered - **Color:** black - **Cutting Width:** 6.44 Inches - **Product Dimensions:** 6.5"L x 3.5"W ## Images ![EZ Lock Universal Fit String Trimmer Replacement Head, black - Image 1](https://m.media-amazon.com/images/I/51lwqQ92WkL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Is the trimmer head plastic or metal?** A: Plastic with the high stress points made of metal. I'm an engineer and there is nothing wrong with plastic if the correct plastic is used and the design is made for using plastic. This head looks like an okay design but I have no idea if a correct plastic was used. So far mine works fine but it does use up a little more line than a regular string head since the short ends are thrown away when you reload. I recommend the trimmer head for the price. **Q: Please; i have a ryobi 4 stroke with a curved shaft. has anyone had any luck installing this unit on my 4 stroke ryobi ?...thank you !** A: Not sure but they do fit a lot of different ones. **Q: Will .135 line work with this head** A: Yes. It is very flexible in terms of thickness of the line. **Q: Will .155 line work with this head?** A: No, the Weed Warrior EZ Lock Trimmer Head is not compatible with the 0.155 diameter trimmer line.

Very durable thus far. Easy to install new strings. Used it for a year now and it does build up grass in the string clips when you cut tall grass I found it best to let it dry then pick it out with a small screwdriver or pick around the spring and button for the string retainer. ## Frequently Bought Together - Weed Warrior EZ Lock Universal Fit String Trimmer Replacement Head, black - MaxPower 333795 Pivotrim Commercial Grade Trimmer Line Replacement Strips .095" x 12" - 24 Strips,white - Shakespeare Weed Warrior Pre-Cut Trimmer Line Strips for EZLock & Pivotrim, .095" Diameter, 24 Count, Red --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/28953384-ez-lock-universal-fit-string-trimmer-replacement-head-black](https://www.desertcart.ni/products/28953384-ez-lock-universal-fit-string-trimmer-replacement-head-black) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-04-22*
