    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!

    Very sharp and cuts great
    This blade comes extremely sharp and ready to cut. It is easy to install you just have to have a blade installation kit to hold it on. Instructions are not completely clear on which way to put the blade, but if you know which way the head turns its easy install

    BEST Choice for cutting saplings, small trees, & harvesting Christmas trees!
    This is the BEST sawing blade offered by Stihl. However, this blade is not recommended for general brush control or weed control. This blade is done for the day on it's first trip into the ground! It should not be used where the ground is irregular or where sand & rock are prevalent. Keep it away from trunks that are contaminated with soil. In other words, keep it high & dry and you'll be just fine. These comments apply to the other sawing blades in the Stihl line as well.

    CONDITIONAL Recommendation!
    This cutter head kind of fits a niche between a Sting-Line trimmer & a Cutting Blade. I have used mine occasionally, but it sets on a shelf in my shop because the Cutting Blades better fit my uses. There are specific uses that it will fit just fine. If you are cutting weeds that look butchered or shredded when cut by a String-Line trimmer, this may be for you. Some hollow-stemmed or moisture-laden weeds cut well with this Poly-Cut Mowing Head. However, it will wear down quickly when ... read more introduced into woody brush. I had good results when cutting Canadian Thistle & Knapweed.

    Great for tall grass
    I got this head a few years ago for my FS-40C when I was trying to figure out what would work best for what I do. I used it a while for everything I do at the farm and it was okay, but I found that it is inferior by a wide margin to the Autocut string head I've replaced it with for shorter grass and trimming around trees and fences. This head isn't useless though. It shines in tall grass and weeds. The FS-40C turns clockwise, so I take the usual big swath to the right when I cut. This head does ... read more an excellent job of cutting tall grass at the bottom and not sucking it back into the cut like a string head does. This means that you can cut the grass and throw it all in a row or pile very easily. This head also does an excellent job of cutting at lower throttle because it needs less power to work than string. The only things I don't like are that the blades could be longer and they wear down too easy on heavier weeds. If they were made of metal this would be incredible.

    Excellent for brush and grass
    My parents had one of these trimmer heads on a sthil brush cutter when i was growing up. I used it to mow fence lines, drive way banks, and trim around the house and barns. When i got older and bought my house i also bought a fs55r and when i picked it up from the dealer it had a string head on it. I dislike string heads so much i gave it to the dealer and had them install the poly cut head. I will never use another style of head on my trimmer. I get two or three trimming rounds at my 6 acre ... read more property from one set of blades.

    I love my Stihl FS55 string trimmer but could never complete my entire trimming job without stopping to remove the top of the bump-type head to re-set the string because it would break flush with the edge of the head. With the new Fixcut head I can easily replace the string in seconds without removing the head. I LOVE THIS PRODUCT!! If you buy one of these Fixcut heads, you will not be disappointed. I should have bought this sooner. This head should come standard on all their models.

    Line breakage issue solved..with common sense???
    Lines and chains of any kind break within thier specifications due to a change of Chemistry of conditions and maintenence or storage related to the tool or machine. ALL line must put into a pail of water 24hr after purchase and 24hr just prior usage then stored in a bucket with damp mold resistant sponge as not to dry out. Secondly. Like a chain saw bar clean after use and check for burs. Not cleaning, deburing and lubricating will cause anything to fail that is not in a sealed environment.

    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.

    simple, works great
    I just bought my second what I call non bump feed head.The first one was great and it lasted for several years. the new one is a little bigger and works just as great. Will never go back to bump and feed.The new one came with several pre cut strips of trimmer line which is unbelievable. I did my complete lawn weed wacking and edging and never had to replace the two pieces of line that I started with. these pre cut pieces were black with gray strips but I can't find it to purchase more. hopefully ... read more it will be out soon. bought my first Stihl product a chainsaw about 18 years ago and still use it. Since then anything I need if Stihl makes it I buy it, You can't go wrong with a Stihl anything.

    Love it
    The DuroCut Line Head was very reasonably priced and works wonderfully. The line is very easy to replace on the head and I'm very happy I purchased the head when I purchased my trimmer.

    Excellent Head
    Easily installed the DuroCut Head 20-2 and have been very pleased with its performance. It has been very reliable and it is very easy to change the strings. The DuroCut Head is much less hassle than a bump head. Thank you Stihl for making this head and pleased do not discontinue it.

    Using it with a FS 560 is unbeatable
    I purchased two of these for my FS 560 that came from my Southern States dealer in Lebanon, VA. The team there is great! Anyhow, this blade is unbeatable. It does great on grass, but can tackle nearly anything I can throw at it. We are in rocky limestone terrain, with autumn olives, blackberries, wild roses, etc. It's a mess of over grown pasture field, but this combo cannot be beat. The FS 560 is a beast of a machine, and the other blades, the scratcher, and the circular blade have their ... read more places, but this best all round one.

    The BEST overall cutting attachment for Brushcutters/Clearing Saws!
    I have logged over 4,000 hours of cutting with the 350mm X 3-tooth Brush Knife. I've whacked green wood upwards of 3" in diameter. The blade clears itself well from tangling of wire-like weeds. It is easy to sharpen by hand or grinder. Make sure you keep it balanced. The two-sided feature means you can flip it over in the field & keep on cutting. This blade is not on the recommended list for the FS 460 series Clearing Saw, but I can tell you that it works just fine on that unit which has ... read more adequate power to swing it. This blade will clear all kinds of grasses, weeds, brush, and sapling trees.

    The Best Blade For Me
    I have an FS110, and use the OEM string head, the scratcher blade, and this brush knife. This brush knife is by far the best of them. Nothing within reason stops it. It chews through thick grass, eats saplings, and even chews away at thicker brush and small trees. I used it to clear some shooting lanes for deer season, and it did the job easily and efficiently. The only downside to it is somewhat petty: the price. When you get down to it, it's just a small piece of metal with some sharpened ... read more edges. But since it does the job so well I can accept that it is a little bit more money then I think it should be. Overall this is the blade to have if you could only choose one. If you have more than just grass to cut, get it, you won't be sorry.

    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!

    useful accessory
    I bought the 4 bladed model. As they come from the factory they're not really sharp. Works well on brush up to 3/8 inch. Works well on grass but has a small cutting diameter. I prefer the poly-cut blade for light brush and all around use.This one is better in slightly heavier brush. Watch this one in rocky ground. I don't like switching blades, but if what I will be cutting is mostly brush, I will put this one on to save my poly-cut blades.

    Good overall blade
    This has been a great overall blade so far. I just got it a few days ago and it is making a huge difference over traditional line. It is the 8 blade model installed on a FS110. I am cutting mainly overgrown grass (about 7 years worth) and mesquite brush and saplings. It lays the grass right down and will get up to 1" saplings in one pass. I have taken on larger saplings (up to 2.5") with either a few bumps, or using it like a saw blade. I have 4 acres of land to cut with it and it is working ... read more great so far! The grass I am dealing with is extremely thick and years of accumulated matting and overgrowth. While this blade isn't getting the extremely thick stuff down to earth with ease, it is making it more than manageable for my riding mower.
