Rated 5 out of 5 by from absolutely awesome This is the only trimmer that you need on your trailer. It is powerful enough to do brush clearing jobs yet versatile enough for the trimming around the house. What I love most about it is that you can run at half throttle while doing your normal trimming but when you run into the big stuff just squeeze the throttle and you have more than enough power at your fingertips. When cold the trimmer will start on the second pull, the rest of the day just grab it give it one pull and go to work. You can't go wrong with this trimmer.

Rated 2 out of 5 by from Power as advertised but hard start and rough to no idle I purchased this trimmer new from my local dealer after reading the reviews and doing lots of research that I didn't think I needed since I believe strongly in the brand because I have been running Stihl chain saws for over 20 years. That said, I am VERY disappointed. For once I actually took the time to read the manual and follow the break in steps. It has been hard to start and has ran rough from day one and although I thought it would get better after break in, it has not. I was actually able to see the shaft flexing from vibration while waiting for it to warm up (yes, fresh gas and Stihl oil). I am in Ga. so when I'm trimming, its not warm out, its HOT. I broke the unit in and adjusted the idle as per the manual, however, it either over-revs at idle, or stalls within about 30 seconds of idle time. As for the bump head, as other reviews have stated it could be better but I would be happy if it would run long enough at idle to go from a tree to landscape edge and not have to re-start or keep it running at half throttle. I do agree the power and torque are remarkable at speed, but what good is it if it wont stay running? I have no problem paying a premium for a quality product and in fact I would rather do that than have problems, I just don't like having to do both. I will be returning this to my dealer and hope they make it right.

Rated 5 out of 5 by from I can't imagine a better trimmer I just purchased the 91 R and I'm glad I did. I carried it straight to the farm and put it to the test. It performs great! I recently bought a Farm Boss chainsaw and it's what made me want to stay with Stihl, I love it. I spent over two hours with my new 91 in a wet highway ditch and around my pond, cut waist high weeds. Even getting the lines in the water wouldn't bog it down. It was quite and smooth to run , and it started on the first easy pull every time. That is a must! Believe or not, the whole time was on the 3/4 tank of fuel that came in it! When I was done I wasn't 'buzzing' all over. I'm very happy and impressed, and can't wait to try the saw blade out in the brush.

Rated 5 out of 5 by from Great trimmer for the price Purchased 1 year ago. Still starts on the first pull and has had 0 problems. If your tired of buying junk ones every year then get a Stihl.
