Review: Fit my old Husky 326Rx using the suppled adapter. - Just ordered & installed the Speed Feed trimmer head on an ancient Husqvarna 326Rx brush cutter. This is a 20-year-old H/D machine, the kind with bicycle handlebars and a shoulder strap. Once installed, it wound new line just as described on You Tube videos., that's the best part. Took a full 14 feet of .090 heavy trim line. I need everything H/D here on my ranch. This is used for culvert clearing and heavy weed control. Pros: head came with a full set of adapters (thankfully) and once assembled for my machine, it ran well and bump feeds easily. Cons: No instructions of any kind, just a head and a bag of adapters and some cheap .080-line wound in the head. It's not physics to understand what needed to be done, but a simple sheet would have been nice. I probably could find it on-line, but I could see the solution and just went ahead. The installed center threaded arbor was too small for my mount. I pulled the head apart and replaced the installed arbor with the larger (supplied) one and then installed and wound line the way the You Tube video shows. No issues. Watch the video a couple times and you will have no problems, and I thank Chickanic for the recommendation. My old head was a hassle to wind new line. And I had 20 years' experience doing it! Recommended. Review: Great trimmer head but with minimal instructions - I will start off this review with details that apply to everyone and should have been better explained in the poorly written instruction sheet: Despite the application chart indicates fitness, this head will not work on all or some Stihl curved shaft trimmers. The product description on desertcart correctly states that it will not fit these trimmers. It does not come with an 8mm RH bushing. Here is a better explanation of the parts and how they fit... In essence, the spinning direction determines the thread of the bushing, the core color, and orientation of the spool. Select the wrong core and the trimmer cable will not dispense. Left Hand (LH) bushings must be inserted into the black core while Right Hand (RH) bushings should be used with the white core. The choice of core also determines which side of the spool faces up. Specifically, the white core with RH bushing is assembled with the spool showing the letter "R". The black core with a LH bushing should be joined with the spool oriented so that the letter "L" is visable. When correctly assembled, the core will extend beyond the spool as shown in the photographs accompanying this review. . The spool sides are mentioned in the instruction sheet but I believe this needs to be clarified with photographs. So, how does it work? The trimmer line goes in easily and loading is simple. It may be reloaded in a minute. When you need more line, just tap the head against the ground to extend the stored trim cable. It works well and and can save considerable time. In summary, I highly recommend the Shindaiwa/Echo Speed-Feed® 400 Trimmer Head with one reservation: Do not trust the application instruction sheet chart. Check the list of included bushings and studs to make sure it will fit your trimmer's mounting method. And here is a bonus tip.... Search for the web for "SpeedFeed® bullet proof" mod using a 3/8" bolt, a fender washer and nylon insert locknut. It will extend the trimmer head life. ## Features - Genuine Shindaiwa replacement part. - Speed-Feed Head 400 Clamshell. - The Speed-Feed 400 is universal and includes adapters for use on both straight shaft and curved shaft models. - Can be reloaded without disassembly in 30 seconds or less. - Professional tap-to-advance line feed mechanism. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #12,736 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #89 in String Trimmer Replacement Parts | | Customer Reviews | 4.2 out of 5 stars 2,368 Reviews | ## Images ![Shindaiwa 78890-30000 Speed-Feed 400 Universal Bump Feed Trimmer Head | 78890-30000 - Image 1](https://m.media-amazon.com/images/I/71nFJohk0AL.jpg) ## Questions & Answers **Q: Will this fit the Stihl FS-90r?** A: Stihl FS90R has 10mmx x 1.0 threads, yes it will. **Q: How do you get more string out when it wears down?** A: Tap it on a hard surface. It will feed out some string, and the excess will be removed by the cutter on the trimmer head (you didn't remove that, did you?). If you tap in the grass to do this, it will create a little burnout like those alien crop circles. **Q: will it mount on a 3/8 fine thread stud. (not left hand thread)** A: It comes with a 3/8"-24 bushing that is right handed, for Echo GT series and others. **Q: Will it fit my stihl 110 km?** A: In looking at the paperwork, I do not see that model noted. The Stihl models noted are in the FS--- series.Ken ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fit my old Husky 326Rx using the suppled adapter. *by M***E on April 19, 2026* Just ordered & installed the Speed Feed trimmer head on an ancient Husqvarna 326Rx brush cutter.
