Review: Fits Stihl FSA-80R - Got this to handle low cut grass like perennial rye that the normal weed wacker head would just push over. Works fantastic and fits my Stihl AK series FSA 80R perfectly. Looking forward to getting my grass getting healthier due to the cleaner cutting action.
Review: Best yard work purchase I've ever made - I bought this item after we put up approximately 500' of new wood fencing because I didn't want to damage it with a weed eater. I have a Craftsman and a Stihl, and this item requires a straight shaft (which neither had), so I purchased this trimmer attachment https://www.desertcart.com/dp/B085VSFH1G?ref=ppx_yo2ov_dt_b_fed_asin_title to add on my Craftsman. The trimmer came with a J bar a shoulder strap, both of which I installed on the Craftsman, and I was glad I did because I'm a 5'2" female and this item is heavy. Go slow and let this tool do its job. I used it around concrete curbing as well as in the front and back of my fence. It works especially well if there is clearance under the fence to trim the grass on both sides. It's not as messy as a weed eater, allows you to trim a larger area more evenly, and gives your edging a professional landscaping look. Yes, it's pricy, but having the right tool for the job will save you a lot of hours. Buy it!

## Questions & Answers

**Q: Does it works with ego**
A: it works perfect on my ego

**Q: Is it compatible with ryobi electric trimmer?**
A: Yes. The correct size sleeve is already installed, and you'll use the square shape drive shaft attachment. Use a pair of needle nose pliers to more easily drop the square piece into the rotary scissors shaft, then just push the trimmer head into the rotary scissors shaft.

The guard won't fit anymore, its about 1/16 of an inch too short. But thats fine, nothing sprays towards your face with this thing.

I've never changed an attachment on a string trimmer before, and it took me about 3 minutes to attach the rotary scissors head.

**Q: Will this work with any battery powered machines?**
A: Not all but some, yes. The motor can't be near the string head, it must be at the handle end because the string head must be removed and replaced with this tool instead. It works on my 60v Dewalt. See review pics for the model number. I posted some of mine.

**Q: Will this work with Stihl kombi and drive shaft extension?**
A: This works perfectly with the Stihl MK55R combi tool using the supplied drive gear and shaft spacer.  Proper rotation, proper speed.  Removing the String trimmer takes about 3 minutes using a T-27.  Replacing it with the rotary scissors takes about 15 minutes including injecting the grease.  Don't forget the GREASE!!!!

### ⭐⭐⭐⭐ Tradeoffs against the Stihl scissor head...
*by G***G on May 30, 2022*

I already had the Stihl RG-KM connected to a KM131R power head. I was curious about the Stens, so I bought one to compare. Short answer: they both work great, but with some tradeoffs. I was going to mount the Stens to a shaft to fit the same Kombi motor, but then I realised that it would fit my FS-311. That gives me a real harness and handlebar grips. Comfy! The 311 has a 28mm shaft, so no spacer sleeve required. It takes the largest spline adapter. Assembly is where I hit my biggest complaint of the Stens: Rather than use a longer cuff with 2 bolts, they opted for a single bolt cuff and a pointed set screw. This will cause permanent damage to the tube. My solution is to use the set screw to mark the tube, then drill a hole for it to pass through. Anti-rotation accomplished, and I can still change the head back to my wide swath poly-blade head when I want to motor through thick weeds. btw that big poly head is great, but I end up looking like I fell into a vat fo wheat grass smoothie. That aside, the Sten cuts great. It is very loud, and draws a fair amount of power. It has counter-rotating blades, but the bottom blade has the most exposed surface to the grass, so it will still lay down some material and miss cutting. A couple of swings cleans it up. Also the spinnig blads will spark if you bump into concrete (like the edge of a driveway). Now the Stihl RG-KM is very different. It oscillates, so nothing gets pushed out of the way. It is quieter, but there is a noticible vibration due to the oscillatory motion. It cuts so smoothly that I have sliced right through the ground under the grass without noticing. It is more expensive than the Stens, but it does come with a shaft. Power demand seems much lower, but I have no way to quantify that. It does spool up faster, and coasts longer. With the Stens, it stops dead as soon as I let off the throttle. The Stihl has a much beefier gearbox, but then there is a lot more going on in there. It is a bit heavier. So, the Stihl costs more, cuts better, uses less power, and comes with a shaft. It is configured for a Kombi engine, but I suspect that it could probably be fitted to a Stihl with a 1" shaft. The Stens is cheaper, and parts are available at a known cost. It is loud and soaks up a lot of power. btw I oil the blades of these units before and after I use them. I suspect that the Stens will quiet down as I use it more. The Stens does recommend sharpening the blades every 10 hours. That will be a pain. My approach will be a spare set of blades so that I can keep a set sharpened. And the Stihl? At the time that I purchesed it blade life and cost were a mystery. I will check with the dealer again. My recommendations: if you have a Kombi motor, go for the Stihl. If you want to adapt to a different system, the Stens is still a great option. Both are a dream to use. Caveat: I hate string trimmers. I use a Badger-head with poly blades for light stuff, and the largest Stihl poly head for big growth. That huge swath really speeds things up. It is faster than my clearing saw for everything but saplings. Both the Stihl and the Stens are recommended by their manufacturers as edgers.Are they nuts? I would only do that if somebody else is paying for the blades.
