FS 70 R

FS 70 R
This professional-grade, straight-shaft grass trimmer is fuel efficient and produces low emissions.

Product Description

As a professional, your time is valuable. The STIHL FS 70 R grass trimmer understands that. It features a powerful and fuel-efficient engine, which means longer run times and fewer refuels. The FS 70 R is also powerful (more powerful than the FS 56 RC-E) and makes quick work of your daily landscaping tasks. Need more line? Just tap the cutting head on the ground and watch as its AutoCut® head automatically feeds out new line. The trimmer is also built to last, featuring a durable cable drive shaft, a high-durability, forged connecting rod and a 4-bearing gearbox. And it’s all backed by a rock-solid two-year limited warranty.

Rated 5 out of 5 by from This product is well made, tough, with plenty of power for its weight. This is the second trim of this model I have purchased. The first unit still runs great. These units are used on large properties (100 plus acres). I select them for their weight, ease of use, and power. They are light enough to use without a harness, edge the lawn, yet rugged enough to trim the pump areas, gates and pasture areas, and other large locations.

Rated 1 out of 5 by from Buy a Redmax trimmer I've had other Stihl products which are fantastic but it seems these new trimmers are at a Homelite level. Garbage. correction, overpriced garbage. My FS 85 and FS 80 were good trimmers. Not great but good. The FS70R is terrible. I used it for just 10 hours and it broke twice in me. I was told not to worry because it was under warranty. I don't want a warranty, want a string trimmer that works. Period. I took it back to Montigue Tool and left it on the floor. I then drove to Campbell small engine and bought a RedMax. I'll never buy another Stihl product again. I have now experienced quality.

Rated 5 out of 5 by from Great value I had a Stihl FS 85 in the past and was looking to replace it, and was a little skeptical how the FS 70R would compare. I was super impressed! Better power, easier starting and better balance makes me wonder why I didn’t do this sooner!It has plenty of power and I like the ability to put a blade on it as well if I need to.

Rated 2 out of 5 by from motor gets a 5 Auto line feeder gets a 0 I love the easy start and that it runs forever. Great design so I don't get a sore back while using it. But...... The auto line feeder is terrible! It doesn't feed when you 'bump' the head. You have to slam the head down. Thats if it's not tangled inside. I spend more time rewinding and adjusting the line than actually using the machine. I'm going to see if I can replace the head with a one that you feed the cut line into. Otherwise, not sure how much I'll even be able to use this.

Rated 5 out of 5 by from Best bang for buck. I purchased this trimmer at my local dealer. And i am very impressed. I’ve used STIHL in the past at an old job which is why i chose STIHL. This trimmer is fairly priced and i changed out the head that it came with for the aluminum head and used thick string like really thick stuff that is used in those big weedeeders with the wheels. And it still has a lot of power and i can easily cut down thick weeds and since the string is so durable i can go forever. So i highly recommend this trimmer.

Rated 4 out of 5 by from A good quality trimmer at a reasonable price I am a long time owner of Stihl chainsaws, backpack blowers and trimmers. I tell people that ask that Stihl vs competing brands (like the other orange ones) is like the difference between a Mercedes S class and a Chevy Impala. There really is no comparison. The Stihl pro line products are better designed, better built, and last longer than other brands. I know because I have owned quite a few competing products. You may pay a bit more for Stihl but their products are well worth the extra expense.The FS70R is well balanced and reasonably powerful. I own an older FS130R and the 70R is noticeably less powerful. However, it is adequate, even for bigger tough jobs. My only real gripe is that the trimmer did not come with s shoulder strap. If you’re using the trimmer for 10-15 minutes not having a shoulder strap is okay. Working for 30-60 minutes really requires a shoulder strap. The dealer where I bought the trimmer did not have shoulder straps in stock when I made my purchase; if they had, I would have purchased a should when I bought the trimmer. The design of the throttle and kill switch is an improvement over the older FS130 I already own.If you’re looking to try Stihl products this is a good model to try because it balances cost and performance well.My only advice is that you use Stihl two cycle oil and non-oxy premium gasoline; if you do your Stihl will start when needed and run for many years without giving you trouble.
