    Great Trimmer Addition
    I just recently bought an FS90 and got one of these with it to clear stubs and small trees from the 5 acres with our new home. The blade turns the FS90 into an unstoppable cutting matching. Anything 3" or under is easy to cut and anything .75" or under is cut while swinging with no more resistance than grass. Highly recommended.

    Good tool for a variety of issues
    Bought for my FS110 to help clear about an acre of mixed undergrowth on my new property. Since it's winter, I haven't had any long sessions with it yet, but what I have used, I'm pleased. Will buzz through small saplings and briars quickly. Can get very close to the ground to minimize obstructions when mowing the newly-cleared areas. Have not sharpened it yet, but the ability to sharpen the blade at home was one of the determining factors in choosing this blade. I suspect that a little file work ... read more will make it sharper than factory and a faster tool.

    Very good choice for brush and small trees.
    I use this type of Chisel Tooth saw blade on my brushcutter and have found it to work quite well on scrub brush and small trees up to three inches. Although it needs to be professionally sharpened, it stays sharp for a long time if you don't get it into the dirt. I purchased different sizes for the type of tree or brush I choose to cut and they all perform exceptionally well. One piece of advise, purchase more than one and you won't have any downtime. Great product for the price!

    Great upgrade from the auto feed string head
    I was frustrated by the design flaws in the auto-feed head. My dealer recommended this head. I am VERY pleased. It is durable and the blades last for many hours of use which translates to months for what I use it for. The blades are durable but not indestructible. They are great on grass, weeds and vines but are brittle and will break against fence posts and trees. I have brick flower beds that I have to trim around. I have to switch heads regularly.

    No Prickly Lettuce
    Tried this product on very tough weed; Prickly Lettuce. When that weed grows over a foot tall most weed eaters shy away. It can grow over 5 feet tall!!! At that size, it has a very woody stalk. The PolyCut Head can chew it up but not over long duration. Not recommended for tough weeds. But it holds it's own very well for what it's advertised to do. Trouble I had was when one of the thermoplastic blades got bent, the blade receded into the body and that made for imbalance so got lots of ... read more vibration feed back through the trimmer handle. I used it for several hours on heavily weeded areas without interruption. Better may be to get a metal cutter for the bigger badder weeds.

    What a great tool!
    I was so tired of trimming the tall grass by the creekside and having the string break or trying to find a place stable enough to release more string. I decided on the STIHL PolyCut Blade. I used it today for the first time and it cut right through the thick grass and blackberry vines like a hot knife through butter. I even hit a rock or two and a stump with no major issues. The blades are still very usuable even though I did purchase the replacement blades, I won't need to at this time. The ... read more blades won't replace the string for certain jobs but this job was done with ease and speed! Love it!

    Great for small trees
    This saw blade has been a lifesaver for cutting down small Honey Sucke trees up to 1" in diameter. This species of trees is taking over Missouri forests. Not so great for Blackberry brush, but Stihe has other blodes that will work on any thorn bushes.

    Saw blade cuts like a saw.
    I put this on my FS240. Brush and saplings fall like trimmer line through grass. Small trees go down like they're cut with, well... a saw! Tree size is limited only by blade depth. If this on a 240 won't cut it, get a true saw.

    Excellent for 1" or so scrub
    I have the FS 130 and I have this. I had no operation instructions and used it improperly and at first didn't like it. Then I was instructed to use it like a scythe. YOWZA!! A small swing and it slices through obstacles, overgrown paths and with some dexterity and improper use can get some of the waist high horizontal branches.

    More efficient than an auto feed head.
    SURPRISED: This is my third season using this head. I had all but given up on using string trimmers until I found this head. Most people probably won't agree on my efficiency comment. But, it beats untangling auto feed spools any day. MAINTAIN: I have found that the head must be taken apart and cleaned on a regular basis. I soap and water to clean & silicone spray sparingly to lube the pins. This is a must if it is being used around sandy soils or in dry conditions. LINE FAILS: As to the pull ... read more out problem I find that the line striking rocks or rough cement to be the biggest cause. I find that having a pocket full of inserts and a pair of pliers is much simpler than fooling with auto feeds.

    Very durable. I use .155 spiral line.
    I bought this with my FS-56-RC-E trimmer because it was the only head that was big enough to use my .155 spiral line in. I store my line in water until I use it. The ONLY time I have to replace my line is when I use my trimmer as an edger by cement, or when I get too close to the chain link fence. I use 2 lines in the head so that I have 4 pieces cutting. I love this head. I've used it for 2 seasons with absolutely NO problems.

    Fantastic Blade!
    I have the 8 tooth grass blade, and it cuts all my thick brush. When I first bought this blade, I thought it could only cut thick grass because it is a "grass blade", but it cut all my wooded brush just fine. This blade even cut some trees that had a diameter up to an inch.

    Cuts like a hot knife
    This blade rocks. Cuts high grass like a hot knife to butter. I cut through saplings up to 2 inches with little effort. Grass is no match for this blade. It's like a lawn mower but with out the bogging or clogging factor!

    FS 91
    bought this blade for my FS 91 to cut small saplings. Works great. Cuts them down with ease. Very satisfied!! The handles on the FS 91 make it easy to maneuver.

    Durocut 2-20
    Use this head with .095 string instead of buying expensive little cut pieces. you will need a good pair of cutters. use the thick precut pieces it comes with to get right size of string. you have to spend time cutting these pieces, but I only go through about eight per lawn. I run the weedwacker at 70% power so string doesn't break you have to find the sweet spot where you're cutting effectively and not breaking the string. love this durocut head love my Stihl weedwacker. another thing they told ... read more me to start it on choke. after it warms up just start it without putting it on choke only on starts where she sits a long time choke and prime when she's warm just pull string to start 10/10 best weedwacker I've ever owned get the durocut 2-20 and spend your time productively trimming.

    Excellent compared to the bump spool line trimmer.
    I bought the Stihl KM 130 motor head and also attachment for the brush cutter. I have another line trimmer attachment with the bump spool trimmer and always had problems with the line feed. While I'm giving this line trimmer to my son, I bought this trimmer head to change out with the brush cutter attachment. What a difference and joy it is to use. It is not that expensive either and well worth the change compared to the hassle of having to deal with a bump spool. Lines are easy to remove and ... read more change out when needed. You can also get easy replacement lines or buy a spool and measure and cut your own trimmer lines.

    very very happy
    Ok I bought an FS 110R last year tried the following heads and hated them all. Autocut, Fixcut, and Supercut. Today I bought the new Durocut and I love it. Works very well and easy to use. Finally, thank you Stihl!
