  • Loop Handle (R)
    Loop handle grass trimmers and brushcutters are ideal for trimming between bushes and shrubs and other areas where space is limited.
  • Shoulder Strap / Carrying System
    Using a shoulder strap or carrying system helps distribute the weight of the equipment for increased operator comfort and improved maneuverability.
  • Multi-Function Control Handle
    Having easy access to all of the controls on one comfortable handle makes it easy to complete tasks so the operator’s hand never has to leave the handle.
  • Purge Pump Primer
    By pressing the bulb, this small fuel pump delivers fuel to the carburetor, reducing the number of starting pulls needed after an extended break between uses.
  • Upright Translucent Fuel Tank
    Allows operator to easily check fuel level before starting work. Upright position makes it easier to refill.
  • Protected Spark Arrestor Muffler
    Has large baffles which reduce noise level and contains a screen designed to reduce the emission of sparks.
  • Protected Spark Plug
    Protected yet easy to change.
  • Simplified Starting Procedure
    To get started, simply pump the fuel primer, set the choke and pull the starter cord. The built-in stop switch allows the user to turn off the engine with a simple press of the button. When the engine is off, the throttle lock automatically returns to the “start” setting. Your power tool will be ready to be started when you’re ready to get back to work.

Important Information

WARNING! Improper use of any trimmer/brushcutter can cause serious or fatal injury. Read, understand and follow all safety instructions in your instruction manual. To reduce the risk of injury from blade contact, circular saw blades may be used on FS brushcutters that have a limitstop, a bicycle handle and double shoulder harness and not on FS brushcutters with a "J" handle or loop handle.

To reduce the risk of eye injury always wear proper eye protection. Always use the appropriate deflector for the type of cutting attachment, as explained in your instruction manual.

Rated 4 out of 5 by from Overall good but line advance has design issue The power, ease of starting, weight distribution are good. Half the time I use it the string cuts off even and I have to stop work, pull the head off, pull line out and reinstall head. Every trimmer I have had when the line won't advance that means it is empty. Not this one. There is a note in the manual that says to not let string get shorter than an inch before tapping on the ground. You just end up tapping more often so you don't have to pull the head. Annoying.

Rated 1 out of 5 by from Poor Line Feed I sold my cheap trimmer to purchase this Stihl FS 70 and was excited about my purchase as I own several Stihl products . From the first time I used it it would not feed and I have to continue to stop and take it apart and pull the line to advance . I called the Dealer and they said call the manufacture . I called Stihl USA and they instructed me to call the Dealer . I am very disappointed in the Trimmer I purchased and intend to sell it and go with another brand . DO NOT BUY THIS PRODUCT AS YOU WILL BE DISAPPOINTED .

Rated 1 out of 5 by from Uncomfortable ergonomics, weak power, expensive Compared to my old other brand trimmer, the Stihl FS 70 R has weak power, uncomfortable ergonomics when trimming at an angle, and is expensive. I'm disappointed because I wanted a Stihl due to their reputation but I wish I had shopped around other brands.

Rated 5 out of 5 by from Great trimmer for the home owner My wife and I just purchased a home with an acre of land. The property needed a lot of help! Weeds 3 feet high, a hill that wrapped 2 sides of the house. The hill was to steep to take the riding mower too so we purchased the FS70R by recommendation of the sales clerk and I'm glad he did! The FS70R is super powerful and it allows you to switch heads for thicker weeds. It made short work of the hills and other weed infested areas. I don't like yard work but if I'm going to have to do it I want a tool that won't struggle and make me do it longer. The FS70R is a breeze to use, super powerful, well balanced machine that almost makes it fun!

Rated 5 out of 5 by from Excellent machine for homeowners who weedeat a lot This trimmer has more than enough power, durability, and reliability for large jobs/yards. I've had it for two seasons now, and I haven't experienced any problems with it. It is very easy to start if you follow the instructions for starting and for storing in the winter. I have a small, rocky yard and a lot of brush, but I can cut everything up to tree saplings and work for three or four hours at a time without any issues. I've used other brands before, and this STIHL really outdoes them.
