The Stihl FS 40 Petrol Strimmer is one of the lightest brushcutter of the new generation. Modern appearance, convenient operation and very simple starting procedure are the highlights of the new generation STIHL grass trimmer range. The number of steps needed to start the machine has been drastically reduced. The frustration of a flooded engine is virtually eliminated. New 2-stroke engine with stratified charge allows fast acceleration, low emissions, reduced fuel consumption. With bent shaft, loop handle and AutoCut mowing head ideally for trimming small areas of grass and around obstacles.


Reduced-emission engine technology

2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.

Manual fuel pump (Purger)

A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

Simplified starting system

Simply set the choke, pump the fuel primer, pull the starter cord and away you go! The running machine then switches off after a brief press of the stop button. Once the machine is at a standstill, the ignition activates again automatically. Thus the ignition is always ready for starting.

Multi-function control handle

Easy, comfortable thumb-operated control means the operator’s hand never leaves the handle.

    Delivered fast , arrived in box and undamaged. A vital piece of kit for edging medium to large gardens. powerful , light and moveable.

  2. Darren Overend

    Quick delivery, and top quality for the price, starts first time, economical on fuel, line feed easy to use, light and powerful, if you’re thinking of buying a cheap strimmer take my advice, spend a few more pounds and get one of these, you won’t be dissapointed.

    Excellent product but this is no surprise as I have used a Stihl FS40 for many years. The service from Radmore & Tucker was also excellent with delivery in full working order in under 24 hours.

  8. Joe Gummery (verified owner)

    Had it for about 4 days now using it to clear small gardens and allotment plots, put around 14 tanks of fuel already. That’s the only complaint I have is the fuel tank is small but other than that it’s an amazing piece of equipment for anyone.

  9. John R (verified owner)

    I bought this based on brand reputation and reviews to replace my old mcculloch. What a difference. Easy to start and powerful. Makes cutting long grass and weeds so much quicker. Cutting head line adjustment and loading takes a bit of getting used to but works fine. Really pleased with it.

  10. Glyn Roberts (verified owner)

    Excellent service from ordering goods to receiving.Customer sevice first class and items as described five star service.

  15. Roger Elliott (verified owner)

    We found dealing with Radmore & Tucker a pleasure as they were very efficient with the ordering and also with keeping us notified as to the delivery date. When the item arrived it was placed outside our front door, the driver rang the bell and then observed social distancing before we had opened the door. He was very pleasant and wished us all the best!

  16. Roderick Ingram (verified owner)

    Fantastic service from radmore and tucker recommend them every time .the strimmer is a brilliant piece of kit the way that the new wire goes on is totally awesome saves so much time.if you need a new strimmer just get one of these you won’t get a better one and do yourself a second favour order from radmore and tucker as you won’t get better service

  17. Martin Lloyd (verified owner)

    Because of the amount of orders they had to process, I had to wait an extra couple of days. It arrived well packaged and in good condition. Powerful enough to do the job, also making a good job. Very pleased with the FS40, great strimmer, great value.
    The service from the team at Radmore & Tucker was great, I would use them again and recommend them. Pleasure to deal with.

    Awful strimmer. Sits too high and cord cuts in seconds. Totally useless.

  20. Rob The Gardener (verified owner)

    Brill, Thank you all, thank you John for dropping off at home for me.

  21. James (verified owner)

    Starting is straight forward enough but is easy to flood if you follow instructions, the unit doesn’t need that much priming. The strimming head is very difficult to fit and replacing the line, as with most strimmers is a bl**dy nightmare! It could also do with a strap.

  22. Donna Williams (verified owner)

    Excellent customer service as always. A pleasure to deal with and my husband is ecstatic with his new toy!

  23. Ian Gordon (verified owner)

    Great service from Radmore & Tucker as usual, and thank you John for dropping the strimmer off at home, having set it up.
    Competitively priced and excellent service, many thanks all.

  24. brian hooper (verified owner)

    Great strimmer for my needs, delivered very quickly and all set up ready to go, at a very good price.
    Radmore & Tucker very easy to deal with great service, many thanks

  25. Jo-in-Bath (verified owner)

    The Stihl FS40 petrol strimmer is excellent and makes strimming quick and easy – we’re really glad we purchased it! Though the bump feed feature never seems to work for us (or on any strimmer for that matter – perhaps we’re the common denominator?!!?), it’s easy to load the twine.
    The service from Radmore and Tucker was first class. We ordered during lockdown, and as we were considered local, despite being 80 miles away in Bath, it was delivered on their trade van less than 24 hours after ordering. It also came fully assembled, tested and with a full tank of petrol, good to go – brilliant!
    We are extremely pleased with both the product, and other items we included in our order, and the service we received. We would highly recommend and use Radmore and Tucker again. Thank you.

    Excellent all round service

  27. Barrie Sharpe (verified owner)

    Still best equipment I have ever purchased
    Your service was excellent

  28. Stuart Stevens (verified owner)

    Easy to start and cuts thick long grass effortlessly. I was a little surprised it didn’t come with a harness. Excellent service from Radmore & Tucker and thanks to John for delivering it.

  29. Phill Mitchell (verified owner)

    Brilliant service and Strimmer from Radmore and Tucker. I ordered this item at 10am on a Friday morning and it was delivered to my door, assembled, fully fueled and ready to use by 1130am the very next day !! Good machine, easy to start and does the job ! I am very impressed with it. Will certainly use this company again.

  31. J Lock (verified owner)

    Product very good. (The strimming cable supplied with it, not so good. Will have to buy a better one.)
    Delivery not so good, but that was a Parcel Force issue, not Radmore & Tucker.

  32. Jeff Patrick (verified owner)

    Excellent service and probably the best price on the internet.

  33. Joe Bosence (verified owner)

    Excellent service from Radmore and Tucker, would definitely recommend. Strimmer is great, lightweight and a good price.

  34. Nigel Dalton (verified owner)

    Gone back to a stihl product following a cheaper screwfix version that only lasted one season before carburettor pipes hardened and shattered.
    You get what you pay for.
    Started first pull, and excellent price and service from radmoretucker.

  35. Kevin Shinkwin (verified owner)

    So light and easy to use

  36. Christopher fowles (verified owner)

    Great bit of kit, powerful and lightweight. Only thing I would suggest is change the cord to 2.4mm it wont snap as much. As for radmore & tucker very fast delivery and easy website to work

  37. John wheeler (verified owner)

    This is my second one of the same make and model ( the last gave up after many many years of hard work) . This one is lighter and easier to start , but still does the job just as well. Must add radmoretucker delivered within 2 days , and were the cheapest online. 5 star service.

  38. Paul Badger (verified owner)

    Excellent service from R and T, as always

  39. Lee Davis (verified owner)

  40. ERNEST WILLIAMS (verified owner)
