FS 91
FS 91 is rated 4.3 out of 5 by 55.
Rated 4 out of 5 by from Great power Ist time purchasing this size of weed eater has great power and gets the job done quick. Starts easy waiting to see after one year if it still starts this good. only complaint is the strap could use some improvement for easy adjustment and comfort. I have to adjust often pending if I am trimming around the pond or up and down a hill side. The machine is worth the money tho

Rated 4 out of 5 by from This product does not work as well as my FS 90 The FS 91 has the same power as my FS 90 but the FS 90 started on the first pull every time for 5 years without fail. My new FS 91 seems to flood out initially every time I go to use it. It is a bit of a nuisance!!

Rated 4 out of 5 by from Replaced an FS90; the -91 has some minor changes I would not have made. Got the FS91 to replace a broken FS90 (a very disappointing thing, autopsy pending). It is too early in the game to rate dependability or quality, above are the first month or so. I don't know why the change in gas cap (clip to thread) or the choke control. The elimination of the ability to lock the throttle open is a minus. All are comparisons to the FS90. I would call those changes unnecessary, but in no way fatal.The FS91 starts easy and runs strong. I have multiple open acres to clear for fire protection each year and when the fire protection folk ban bladed mowers, the FS-90, now -91, is the go-to implement. it performs well.

Rated 5 out of 5 by from Quality build, starts easily First gas trimmer I have owned. Was concerned about starting and trouble with another internal combustion engine. No worries at all. Easy to maintain, starts so easy. 5 hillside acres was neglected for the last few years and had grass weeds 3 - 4 feet high. Cut through them like butter. Large gas tank would require a refill when the string ran out. I use the 4 or 5 sided string and it works great. Bought a circular saw for it to use on brush and saplings. Works good if you don;t put it on upside down!

Rated 5 out of 5 by from Best in show. Well made, strong, powerful, light weight, easy to start. I had 4 different trimmers in 7 years and none can hold a candle to my STIHL. Buy one today. It's the last one you will need to buy. Why did I ever waste my money and time buying cheapies. You get what you pay for.

Rated 5 out of 5 by from impressed with the power Had an FS 44 for 28 years that was a great machine. Lately it was acting up and need a tune up which I didn't have time for. Went to the local dealer and bought an FS91. Really like it but I'm still going to get old faithful going again just because it has never let me down. I expect the same from my new one. Stihl has a great product!!!

Rated 4 out of 5 by from Excellent power and ergonomics, cutting head, not so good The power head is excellent as is expected from Stihl The newer 4 cycle heads are quieter and idle very reliably once they are broken in. The cutter head however does not handle the cutting cord well at all. If a cord hits a small hard stem then it often breaks off at the cutter head exit and then you have to disassemble the head to get the cord working again..On the other hand when the cord is handled correctly the unit powers through and awesome amount of weeds.
