FS 90
Rated 4.5 out of 5 by 34reviewers.
Rated 5 out of 5 by Excellent all around tool I have used my F S 90 for two years now without a single problem. I trim around a 4 acre property for aesthetics, and I use multiple blade styles to cut brush and saplings and trees up to about 3" in diameter with no problem on another acre. I highly recommend this unit. April 11, 2015
Rated 5 out of 5 by Extremely happy with my FS 90. A very versatile machine! I've had my FS 90 for several years now and could not be more pleased with it. My home is surrounded on all four sides by thick forest, and it is continually encroaching on our yard, so I'm continually fighting the encroaching brush and briars as well as normal weed eating duties after mowing. I run my FS 90 primarily with the 8-tooth metal grass blade, and it slices as easily through brush and briars as it does through thick, heavy grass and weeds. I also trim around my pond and it slices through heavy cat-tails like they are nothing. It hardly slows down through brush up to 2" in diameter. If it's thicker, it might take a few bumps to eat through it, but it WILL cut it down.With the regular string head that comes with it, it makes quick work of unruly grass and weeds around our foundations, trees, retaining walls, steps and such.This is by far the most comfortable to operate trimmer/brushcutter that I've ever used, and this isn't the first professional grade trimmer I've owned. I chose Stihl because the Grounds Crew where I work uses them, and if Stihl can survive those guys and keep them happy, they can certainly do what I want and need.This year, I started maintaining the yard and grounds of our Church and Vicarage, and I bought the FCS Edger Attachment for edging the many sidewalks. It attaches and removes from the FS 90 quickly and easily and does an excellent job. So I can switch back and forth between the Edger and the trimmer head or brush blade. October 7, 2014
Rated 2 out of 5 by Works great - when it works I own 124 acre place, lots of brush, torturous 4- mile one lane drivewayflanked by brush, nettles, tall grass, etc. To maintain, I used StihlFS 56 (not bike handle) and the triple blade steel brush blade (excellentbrush cutter!) . The 56 starts easily, runs fine.But I got seduced into "upgrading" to FS 90 , it was argued that Iwas expecting too much from my 56. Probably tru.e. Heads interchange.Trouble right from the git-go, the FS90 very temperamental aboutstarting. If you follow directions, then it is overchoked and flooded.So… now have to remove spark plug requently, turn machine upside down for hours, put plug back, etc. and NEVER choke, and NEVER use the plastic bubble. Temps here are 60-80 F., cold at night. It onlystarts if it is exactly the right mood. Total contrast to my happy FS56workhorse. which I think would start under water!Am disgusted with the FS 90, especially because my guys who come to work for me spend (waste) so much time trying to start it.These guys use Stihl gear all the time, can rebuild motors, etc.I remain a Stihl fan, and like many of the attachments, have chainsaw, etc. In fairness, we just bought the FS90 for this season, butmaybe it will get better in time. I understand that there is a "break intime" like with 1940 autos when they were new.I use 91 octane, and Stihl mix. June 25, 2014
Rated 5 out of 5 by Lots of torque, light, ergonomic, and (almost) a joy to use. Replaced an off-the-shelf 2-cycle with this, as I've got a lot of land and fence line to cover. It's much easier on my back, with lots of torque and easily dispenses line as I go. I've only used it twice so far, but I've been happy both times; glad I upgraded! June 24, 2014
Rated 5 out of 5 by This is a great machine My FS90 is only a few weeks old but I've already used it close to 20 hours. It starts with one pull, and I like the easily adjustable handlebar with a knob you turn so you don't need tools. May 24, 2014
Rated 5 out of 5 by Great product I use this to trim and as a brush cutter it is very easy to start has terrific power and it handles great. I would recommend to anyone needing a trimmer/brush cutter May 7, 2014
Rated 1 out of 5 by fs90 a disappointment bought to replace fs 76 I've for twenty yrs. Not as much power as my old fs 76. seems to miss after running it at full throttle for very long. Carried it to dealer for this problem. They replaced the ignition module. Still have the same problem. This the first Stihl product I've had a problem with. would not recommend this unit to anyone.
