Rated 2 out of 5 by from PolyCut blades not good Agree with prior post, when blades heat up they deform and get stuck inside head. Asked dealer if other blades available, no. Also need tool to change blades; have used another brand and could change with simple button push and blades were stronger. However will try adding short pieces of line mentioned in other posts. Stihl can do better.

Rated 4 out of 5 by from 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 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.

Rated 5 out of 5 by from Savage I went into the store to get a metal grass blade and was begrudgingly talked into this cutting head. I really had my doubts that it could handle my garden. I had massive weeds (>6' tall) and raspberry bushes. You couldn't walk through the garden. This mowing head went right through everything. It absolutely decimated everything in its path. This thing is a monster in all the best ways.Also, it is incredibly easy to swap between this cutting head and the string trimmer head that came on my FS-56.

Rated 5 out of 5 by from This thing is a BEAST! I bought one of these along with my FS-85 brushcutter 16 years ago, when I was moonlighting mowing lawns. Both the trimmer and head are still going strong. I use a short piece of.105" line along with the knives, and can pretty much cut all day without having to change strings. The flail knives make quick work of high weeds along ditches, and doesn't seem to throw as much debris as my Supercut head.

Rated 5 out of 5 by from Overgrown Weeds Used this cutter head to clear a path through an overgrown lot. 4' tall Canadian thistle, buckthorn, reeds, and Queen Anne lace, were no problem. Ran about 6' wide by 200-300 feet with no major signs of wear. Well worth the price

Rated 5 out of 5 by from Great product when used with a single piece of .130 cutting line I use an 18 inch piece of .130 cutting line with the plastic blades. Need to force the line into the restrainer in the middle of the head with a screw driver. Use of the line prevents blade breakage when cutting next to rockeries, fences. Necessary to change the line when it wears down . I

Rated 4 out of 5 by from This product has pretty good features on it. its easy to use and very quick and easy to change the blades. I used this product over the summer last year at my job. I used it for about 2 1/2 months and i had to switch to a different blade. It cuts very well in thick and tall grass but it you hit a tree, rock, or piece of metal the blades get dull then break off. The blades are expensive for what they are. i can go through about 2 packs of blades in about 3 days where i work. I would recommend that if you buy this weed eater head you just cut where you know there's just grass and not rocks, trees or metal.
