Are You Ready for a STIHL?

FS 40 C-E is rated 4.4 out of 5 by 356.
Rated 4 out of 5 by from Good trimmer but... I really want to like this trimmer but the curved shaft makes you bend more in order to use it. After about a half hour of use you can feel it in your lower back. If this was a straight shaft trimmer it would be a great seller for Stihl. It runs great and does what a trimmer does. I used it over the summer and I'll be upgrading to the FS56 because that's a straight shaft trimmer.

Rated 3 out of 5 by from Okay but not great. I bought this trimmer after a lot of research and talking to friends. Everyone, including the people at the store, recommended Stihl over other similarly highly rated brands. I was replacing a low priced popular model that I had bought 3 years ago. That trimmer never ran well; it had issues with starting and then staying on without choke. It lacked power and despite only occasional use, it stopped working. In comparison, Stihl trimmer is much better. Its weight is balanced and it started without a fuss. I also like that its head does not spin during idling. It cuts well and effortlessly. However, my only problem after one use is that it DOES NOT advance the line upon tapping. To think that an advanced company like Stihl would not have figured out a simple archaic mechanism of line feed is disappointing. Now, I am having the same fear of picking up this trimmer to do my yard work. I had to stop trimmer after 3/4th of my work and it is sitting in the garage. I may try to work on it again but honestly I am annoyed.

Rated 4 out of 5 by from Overall a good product Replacing the trim line on a dual line feed is time consuming.

Rated 4 out of 5 by from works hard, starts easy , dependable. Bought this trimmer several years ago. Have a 3/4 acre property that I keep free of weeds,so this machine gets a work out. I generally run it until its out of gas and usually have little problem starting it while its hot. I some times put in a heaver line than recommended to cut around rocks and cement.I have many power tools and I don't want to collect any more so I like the idea of optional attachments. Good product in the right hands.

Rated 3 out of 5 by from Trimmer is too short I was disappointed after my purchase that I could not return it, I am a 5ft 6in tall female and the trimmer length is way too short for my height, Also was disappointed in the diameter of the cutting field. I know my husband will never be able to use this piece of equipment. At 6'8" he will not come close to the ground, little lone grass or weeds.I hope that in the future you will consider your customer's physical characteristics in any sale.

Rated 4 out of 5 by from Great Trimmer So far, I am loving the trimmer. I'll give you the pro's and con's. Pro's: Great power upgrade from the electric trimmer I previously owned. It is super easy to start.It is super lightweight.It is fairly simple to work with for things like basic maintenance.Con's:The only real complaint I have with the trimmer is that the trimmer head is annoying when it doesn't auto feed. I had to take the head off and pull the string out 3 times when I was trimming, but I think this because it had cheap string that had melted together. I put a higher quality string on the trimmer, but I haven't used it yet.
Date published: 2017-09-19
Rated 5 out of 5 by from This Product is a awesome machine at a reasonable price. This lightweight and durable string trimmer is excellent for not only use around the home but also keeps up with everyday use as in small businesses. Overall an excellent product. Only downfall is the new head on the string trimmer with the two equal pieces of string. I really don't care for it.
