Electric Start Garden Shredder, Mulcher and Chipper for all Garden Waste (FM6DDES-MUL)

If you’re looking for one machine to miraculously reduce all of your garden waste – it doesn’t get much better than this petrol garden shredder (FM6DDES-MUL).

The very first of its kind, the FM6DDES-MUL takes great joy in taking any garden waste you can throw at it and reducing it down to precious mulch which is less than 10mm in size. Gone are the days of choosing between a garden shredder or a wood chipper, this machine combines both and can effortlessly provide you with the functionality of a petrol garden shredder, wood chipper and mulcher all in one very compact machine.

Equipped with a powerful 4-stroke LCT 6HP Electric Start Engine – the shredder mulcher effortlessly works its way through mountains of waste at just the turn of a key. Forget about the time of pulling relentlessly at the pull start cord trying to get your machine started, simply turn the key to start and away you go! The electric start is also equipped with a backup pull start. If you prefer a pull-start-only edition of this machine – the FM6DD-MUL pull-start is available from us directly.

The lightweight and compact design permits you to neatly store away the petrol garden shredder when not being used, and afterwards, wheel it out into the garden effortlessly when you have mulching errands to get past. The machine is incredibly low maintenance and only requires standard engine maintenance as well as replacing the blades when they eventually dull.

The FM6DDES-MUL is a game changer when it comes to domestic gardening machinery. One of the main inspirations behind the machine is for years we have had countless requests from customers for a machine that can handle both chipping and mulching. Many well-known competitor brands have tried and failed at this, leaving customers frustrated. The FM6DDES petrol garden shredder is tried and tested for all materials. Wood older than three days may produce sawdust.

A ground-breaking design implemented within this unique and innovative machine is the ability to completely rotate/adjust the chipper drum to suit the material you’re processing. The fully adjustable angle means that you have complete control over the speed at which the machine will mulch. Mulching a hard material? Simply rotate the hopper and chute to be vertical which allows the machine to process the material into the drum and produce a fine mulch result.

If you only need to chip wood and have no need to mulch or shred green garden waste – take a look at our FM6DD wood chipper.

    Great wee machine and lots of power. Only thing is that it is difficult to transport as no handles. 5* if handles can be made available for retrofit.

    Arrived promptly. Opted for pre-built. Came wrapped in celaphane ( whatever it’s called ). Will be using it in anger this winter.

    Very pleased with the mulcher so far. It’s small, easy to move around, and has coped well with everything I’ve put in it. I wanted a machine that draws stuff through and on the whole that works well. It is powerful for its size and I’ve been surprised at how much work I can get through. Instead of piling up stuff ready for a suitable opportunity to burn it, now I clear an area, chip it and put it on the compost. The chips are a perfect size and it’s much more satisfying actually using the waste material. The outlet being close to the ground is frustrating but you can move it. I made a stand for the machine and that works well to raise the height. Would recommend the mulcher for anyone with lots of garden waste, and even gardeners who need that capability. And the electric start is so much easier.

    Decent price, fast delivery, easy to set up, apart from the battery connections, which took me a while to get right – I should have loosely fitted the terminals before installing the battery carrier. But, first time start on the key, efficient shredding and chipping so far, although it hasn’t been used in real anger yet. However, I don’t doubt it will fulfill all my needs. Recommended!

    Delivery was quick and everything was there.

    Putting it together wasn’t super easy, best to add the engine and battery holder, in my experience, before you put on the lower chute and connect the leads to the battery before mounting it in the holder. It does mean you have to tip the shredder back to mount the chute though and it’s fairly heavy.

    You need 10 and 13mm spanner’s and sockets and a Philips screwdriver for the battery terminals.

    600ml of oil overflowed my engine a bit.

    I was left with two long bolts a couple of large washers and a couple of crinkle washers over.

    Started first time, yet to shred anything

    So far so good, very impressed. I agree with other users that the instructions should be clearer about fixing the starter battery box at the same time as fitting the body to the stand – same four screws so you need to do both at the same time!

    excellent wood chipper. I live in France but bought a chipper direct from UK which was shipped over within 3 days. i bought the 6HP chipper/mulcher which i use constantly as we have a very large garden and woodland area that hasn’t been maintained for 12 years and has thousands of saplings that have seeded everywhere. I spoke to Mike in technical support who advised me on all aspects of the chipper. Overall very happy with my purchase and would definitely recommend the products and also the support is excellent

    Reçu en 4 jours. Montage assez facile mais il manquait une notice spécifique sur le site lorsque je l’ai reçu. Démarre bien et broie très bien le bois et les végétaux. Par contre il faut enlever le bas de la trémie de sortie sinon ce qui est broyé bouche rapidement la trémie. Le gabarie de grosseur du bois à mettre dans la trémie est gênant si on broie des végétaux, mais on peux l’enlever temporairement. Cela aurait été pratique de mettre une poignée à l’extérieur de la trémie d’entrée pour le déplacer. Je l’ai utilisé plusieurs fois et j’en suis satisfait. Il faudra voir à l’usage comment il se comporte.

    As a retired engineer I found the self build version ok but a few more pictures of the battery installation would help.
    In action surprisingly I found the petrol version is quieter than my neighbours electric Forest master chipper only version. Mulching works best if you remove the branch restrictor plate, size of mulch is ideal size for composting and the small feed hopper works best with a mix of woody cuttings to keep to sustain a reasonable through put. Regarding long straight woody conifer branches (up to 50mm) the results are very good but as with all smaller shredders a little patience and technique is required at times. I use a small rubber ended push stick to clear small wood pieces when the drum occasionally becomes stuck in the stop restart process, this keeps fingers out of harms way.

    The use of a ground sheet works well for catching the chippings and mulch as you do need to keeping moving the machine to avoid the exit chute from blocking, if you are going to use it for chipping most of the time a would seriously consider the optional high level chipper chute to shoot the debris directly into a wheelbarrow. But for now I like the smaller size mulch size chippings and am prepared to spend a little more time on the process.
    Being tall I do find moving the machine over any distance around the garden is a bit of a pain, I would like to see some photos of the optional bolt an handle as a potential solution.

    Overall I would definitely recommend this machine for its build quality, light weight, debris size when chipping and mulching due mainly down to the grunt of a superior petrol engine. Great for large mature gardens and I actually look forward to using this machine but as with all powered garden machinery you need to exercise a healthy respect for safety and be reasonably practically minded to gain full benefit of this impressive piece of machinery.

    Assembly was nice and easy. One piece of advice. Connect battery cables To battery prior to bolting the battery tray to the frame.
    Have not used to chip or mulch yet

Do you have to change blades to chip and shred/mulch or do the same blades do all jobs. C asked on October 26, 2022

No change is necessary for chipping or mulching, the machine is always prepared to take on either task. You can make adjustments to the angle (pivot) of the drum which better suits the material you're processing. This allows you to have complete control over the speed at which the machine will self-feed.
