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 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.

Rated 5 out of 5 by Almost 16 yrs old! 'I've had my FS 90 since they 1st came out in 1998.I use a brush blade as well as tall grass blade along with the Trimmer head.All I've had to replace in 14 yrs is the trimmer head.Starts right up.Easy to maintain.Never lost power in all thee years!

Rated 1 out of 5 by Underpowered for brush and small trees. Works great on grass, and dealer said it would cut trees up to 2" with a blade. That was not true, it will only cut 1/2 inch buckthorn, bigger than that it stalls. Returned unit to dealer he said it is developing normal power, but might need some break in time. Ran several more tanks of gas thru it no change. I bought it because I needed more power than my FS 45 which has been great for several years in grass but could not handle small trees. Sold the FS 90 in disgust and will never buy another one.All other products from Stihl have been excellent but this one is way under powered for cutting small tree shoots. Limit it to grass and it will be good. August 12, 2013
Rated 5 out of 5 AWESONE UNIT!! Don't pass on this one!! AWESOME UNIT!!• Bought mine back in 1983 with a new 5 Acre property.• It has served me well and replacement parts are available too.• This Puppy will cut through 3" Diameter Tree like a Hot Knife through Butter.• Wipes out Blackberries, Ivy, you name it with EASE!• Takes a little time to learn to use, but it is AWESOME once you pass the learning curve.• A little Heavy, but the QUALITY is obviously there and will tackle any task.
