  • Bike Handle
    When used in conjunction with a harness, the bike handle allows the machine to be easily guided, enabling a smooth horizontal mowing action to cover large areas quickly and efficiently. With soft grips for increased comfort, the bike handle provides greater control and helps reduce operator fatigue.

  • 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.
  • IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor measures the air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor. This keeps the RPM at a consistent level, even when the air filter begins to clog.
  • Tool-Free Handle Adjustment
    The central wing nut enables easy adjustment without the use of tools. For transportation and space-saving storage, the handle can be rotated 90°.
  • 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.
  • Anti-Vibration System
    STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
  • 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.

FS 240 is rated 4.8 out of 5 by 36.
Rated 5 out of 5 by from great power This is my 3rd Stihl trimmer in the past 25 years and is the best. Easy start. Plenty of power. Gas tank large enough to work for a few hours. Overall, excellent and easy to recommend.

Rated 5 out of 5 by from It's a beast of a line trimmer It starts easily and runs smoothly with little vibration. Plenty of power and very controllable with the bicycle grip handlebar and shoulder straps. Seems to run forever on a tank of gas. I've got a little over 13 acres to maintain and this tool is going to see a lot of use.

Rated 5 out of 5 by from Works great for tall people. Started up only 2 pulls out of the box. I'm 6'3" and I highly recommend this product for taller people. The balance of the machine is excellent for its weight . The powerband is amazing considering the fact that the fs240 is a true two stroke.

Rated 4 out of 5 by from excellent power After reading reviews wanted 240 or 311, found 240. starts easy, runs good, lots of power. the grass cutting head is terrible, small stems or heavy grass kept burning the line and causing several rethreads (7) in 1 hour. might be the string from factory?for the price expected more. will try new string tomorrow see if better. may need to get metal blade ?Overall like the design and power

Rated 5 out of 5 by from ABSOLUTE BEAST As a professional tree spacer I had to keep telling myself that I was not going to get a grass trimmer/ brush cutter to have the same quality or close to the same power as the clearing saws do. Boy was I ever wrong the Stihl fs 240 has LOADS of power DO NOT under estimate this brush cutter it blew my mind away with how well built this machine is and how much power it has as everyone else has said it’s a very user friendly unit to operate. Wish I had of bought this a long time ago. DEFINITELY recommend buying one

Rated 5 out of 5 by from A boss of the saplings. I got this saw to help clear between trees filled with Yopoun. It cuts all the way to 3 1/2” like butter. A real work horse that has saved me from a ton of back ache trying to do the same job with a chainsaw. I fully recommend to anybody who has some land neading cleared and cleaned up. Use the Stihl metal blade and your golden.

Rated 5 out of 5 by from Powerful, easy starting, easy to handle and control after adjusting trimmer and harness. I bought this machine to clear and trim around a hunting camp lake.Willow, locust, and birch saplings with thick olive and blackberry bushes all filled in between with heavy honeysuckle.With the brush blade and the cutting blade this foliage did not stand a chance.The 240 cut through all of it like butter.The weather was 23 deg and after adjusting the carb heater tab to the cold weather position I had absolutely zero starting and running issues.After adjusting the harness and machine/handlebars for proper fit and balance the 240 is a breeze to maneuver and operate.Not to heavy, plenty of power and easy to use, I’m very happy with the FS240
