  • 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.
  • 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.
  • 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.

Rated 1 out of 5 by from This product has a lot of power but is unreliable. I purchased a FS 90 R and FS 110 R which is very nice light weight with decent power. I wanted to upgrade and I got the FS 240R. It has a lot of power which is nice but I only had it for a few months. One day I am working as usual about to start a job and I couldn't pull the string. I take it to the dealer I bought it from because only a few months old, I still have a warranty. They tore it apart and told me the bearings were damaged which I couldn't understand because I stay away from the rev limiter and I am pretty good about my mix and primarily using quality gas. My shop contacted Stihl and they sent the parts so my weed eater can be serviced. Buyer beware I question the quality of this device.

Rated 2 out of 5 by from Bring back the 250 I have been working in the forestry industry in eastern British Columbia Canada for the last 14 years. Our company has always enjoyed the simplicity , dependability , and lightness of weight in the older 250 model . I was sadly disappointed in the new 240 model . They are hard to control because of the extra weight and more difficult to service, In the extreme work conditions we see working on steep hills in remote areas . I see no need for a bigger fuel tank as we can only carry so much fuel . All in all I prefer the older 250 model and wish it was still an option .

Rated 5 out of 5 by from My second Stihl, next size up, former one lasted 20 years. My dealer, SAWS, in Tucker, GA is and has always been my source for yard equipment and I trust their judgment on all my purchases.

Rated 5 out of 5 by from This product has great power. This is the first Stihl product I have purchased. I have purchased others in the past and spent some money on the products. I got tired of it breaking down while I'm trying to do yard work at the house. A friend told me to look at Stihl so I did. I am just a home owner but like getting what you pay for. I have house, covered patio, front porch, sidewalk, shop, garden, well house, horse pen fence, a lot of trees and a 15' drainage ditch. It is a little heavier than my other one. It would take me about 3 to 31/2 hours with the other brand that I spent money on. Now I get it done in 2 to 21/2 hours. This 240 was not cheap but WOW! The power it has is remarkable. Since this purchase I have purchased a Stihl back pack sprayer and a 600 backpack blower. AWESOME PRODUCTS!

Rated 2 out of 5 by from Rediculously heavy replacement for the 250r. Having used a FS 250 R commercially every season for the last 10yrs, I was surprised when the dealer had said they were discontinued for the new FS 240 R. Which is just an awful replacement for a once beautiful product. It is so rear-heavy that all it wants to do is flop back. Holding it with one hand in and out of the truck is a constant strain on the wrist as you fight to keep it level. Trimming without a strap on causes much more fatigue than the 250r.The choke system is new and 'clicks' back once you pull or touch the trigger. Ideal as a new trimmer but as it ages, this will be very limiting taking away manual control from the choke, Plus it is just infuriating when you accidentally touch the throttle and have it undo the choke while trying to start it.Ours lasted 4 months before showing symptoms of a faulty coil. Turning off after a couple minutes of use. I really wish they would bring back the 250r.

Rated 5 out of 5 by from Built to last. I've had my fs240r for a year now and use it often. It starts on the second pull of the cord every time just like the day I bought it. I've never had a problem with it and maintenance is easy and takes only a few minutes. I will never look at a different brand. Ive had the same experience with all my Stihl equipment.

Rated 5 out of 5 by from 240 R is a brush shredding monster! I have been a part of the landscaping industry since I was a junior in HS all the way to currently, now as a landscape company owner. I have used just about every type of trimmer made. Stihl has always been the most reliable in my experiences and just takes a serious beating and can take some serious abuse as well. More than any other.I disagree with the other reviewer regarding the 240R vs 250R. I think the 240 eats the 250 for breakfast. I have probably owned 10 250's in my life and still run 2-3 of them. That's how good they are. They just won't quit. If I could find more parts for them I'd still be running all 10.The only thing that the 250 beats the 240 in may be power to weight ratio. I don't think there is anything else the 250 beats the 240 at. If you think the 250 has slightly better top end, try removing the spark arrester. Just saying, they usually coke up and cause terrible performance anyway. Just watch operating in dry conditions! The 250 is noticinly lighter and when trimming for 3 hours straight you will notice every ounce of that trimmer. Oh and the 250's exhaust will burn the bottom of your forearm if your not careful. Never had this problem with the 240 even after 3+ hours of continuous use. I'm sure all you veterans can attest. The 240 is a bit on the heavy side for younger less experienced employees but is the go to trimmer for any serious professional faced with higher than normal grass conditions. The 94R is a great lighter weight choice for a beginner or intermediate user in a professional setting OR if your shoulders/forearms just need a little break.
