Garden Shredder Mulcher and Chipper for Wood, Plants and Garden Waste (FM6DD-MUL)

Mulching and composting just got a whole lot easier and more effective with the release of our brand new patent-pending (GB2100107.8) 6HP Petrol Garden Shredder Mulcher.

Compact, Lightweight, Powerful and Robust are the best words to describe our brand new and innovative machine. The first of its kind, the garden shredder is capable of receiving any waste you can throw at it and processing it into precious mulch, crucial in creating effective black gold (compost) for your garden. Paper, cardboard, plants, leaves or any other garden waste can be fed into the machine and the garden mulcher will provide you with invaluable material for your compost bin in an instant. It doesn’t matter whether they’re bone dry or soaking wet from a long night in the rain, our mulcher has been stress tested with anything you can think of and it’s yet to meet garden waste it can’t handle.

What gave us the inspiration for the machine? For years we have received customer enquiries asking if we had a suitable machine for such tasks as well known competitor brands have tried and failed at this attempt, often falling at the first hurdle of being able to process wet green waste such as grass and ivy. Our machine is a tried and tested one-stop shop for all your mulching needs.

Not sure if you require a garden mulcher or a wood chipper? This is a question of the past as the FM6DD-MUL is perfectly capable of also chipping wood into wood chips that are 10mm and below. If you’re mulching material that is particularly wet or likes to stick to the chute, the machine is designed in such a way that you can simply hose down the chutes to clear out any excess material.

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 full adjustable angle means that you have complete control over the speed in 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. The easier the material is to cut, the less steep you can rotate the machine to increase mulching speed. This innovative design works to prevent the engine from stalling as you can easily dictate how much material is processed and mulched at once.

How is the FM6DD-MUL Garden Shredder, Mulcher and Chipper better over competitors? Well, our machine is designed and produced using a steel design. You’ll find that majority of garden shredders available on the market feature a plastic design. Why is steel better over plastic in this instance? The steel design is what allows our machine to be robust and powerful. Plastic designs can damage easily and cause issues down the road. Buy a machine – buy it once, is our motto. 95% of our machine is recyclable metals.

Prefer an electric motor? not a problem! We also have a 4HP Electric Counterpart (FM4DDE-MUL) to this mulcher which is capable of mulching all the same material.

We cover every topic from mulching to creating your first compost pile, preparing your garden for the winter, creating leaf mould from scratch and finding the perfect mixture of household waste for your compost. We provide all the information you could ever need, and if that isn’t enough, we’re just a message away to help you understand anything you may need.

    What an excellent machine!
    We bought a competitor’s version with flail and side-cutter and it was useless, getting clogged instantly with normal garden refuse. This was even with all the extraneous guards removed that reduce any potential efficiency purely in the interests of Health and Safety. One wonders how such a poor design remains widespread on the market.
    In contrast, the FM6DD-MUL has gone through everything put into it, yielding a very good mix ideal for composting. It is also smaller, lighter and even slightly cheaper than the other machine, so we are delighted with it.
    Highly recommended!

  2. Gerard W. (verified owner)

    Very handy for vegetable patch waste. Outlet shute tends to clog up if the material is wet; safety guard on inlet shute understandable, but basically requires taking off as it makes it virtually impossible to insert anything more than a thin stalk with it in place: Of course with guard removed, care needs to be used when inserting material and to ensure hand goes nowhere inside the inlet. Pleased overall, hence rating 4/5.

  3. susan bevan (verified owner)

    Bought this as an improvement on my old garden shredder that just wasn’t up to the job. This one does exactly what I want.

  4. Alan P. (verified owner)

    Overall very good product & service. Shreads branches & clippings to a fine mulch although awkward to feed clippings into the hopper due to the plate in the top. Could do with a handle to transport machine around.

  5. William Mills (verified owner)

    Making mincemeat of the garden prunings
    Chomps it’s way through branches and foliage at a great rate

    Great shredder for branches / woody shrubs including leaves

  8. Jeremy Rashbrooke (verified owner)

    Ordered a Mulcher/Chipper FM6DD-MUL with the additional chipper kit. Came within 2 days. Full instructions and straight forward to put together. The instructions were clear and concise and easy to follow. Only problem I had was there were no instructions included for fitting the chipper attachment. I telephoned customer services and within a few minutes the instructions were e mailed.
    The machine started first pull and works very well. The build quality is good and sturdy. I did remove the blanking plate from the feed hopper as this obstructs the material being chipped. Obviously this is a safety issue. Highly recommended

  9. Harry P. (verified owner)

    Does the job well. It’s compact, portable and churns through most garden waste aside from larger branches pretty quickly. Great for diverting from the green waste bin, or bonfire, to the compost heap.

  10. Matthew Davis (verified owner)

    Brilliant shredder. For someone with a large garden this has fast become invaluable. Anyone experiencing blockages simply isn’t using it correctly. For anything up to 3-4 cm this machine is an absolute beast. Can handle thicker branches but means the blades blunt quicker. Regret not buying one sooner and wasting so much woody material on the bonfire!

  11. Steve Perry (verified owner)

    fabulous bit of kit been waiting for a long time for this having previously been dismayed by an einhell shredder made largely of plastic that destroyed several drive belts and I only got about an hours work out of it.

  12. John Gaisey (verified owner)

    Before buying the FM6DD-MUL ,I read several independent reviews which rated highly the machine.It was not disappointment,I am really pleased with it.The assembly was pretty straight forward,and it started first time.It handled the branches etc very well with no problems,the only material that I wouldn’t mulch too often is cardboard(I don’t want to dull the blades!)
    It is very compact and takes up little space in my shed.
    Overall a very sturdy well built machine from a reliable company.

  13. David S. (verified owner)

    Arrived the day after ordering which was great and assembly was reasonably straight forward although it would be really useful to colour code or label the respective parts needed for each different configuration so you don’t waste time trying to figure out which parts are required or not for your model. Having put it together and added oil/petrol it started first pull.
    Getting the machine to the end of the garden was a challenge as other reviews have also stated, there is a definite need for a handle arrangement to make moving it over uneven ground easier which is why I dropped the point in the score as I can see this being an ongoing problem every time i want to use it…. All things considered from a first use perspective it does a great job and looks sturdy enough to last so would recommend.

  14. Michael (verified owner)

    Delivered promptly. As supplied and assembled as instructed, the machine is not effective. With the baffle installed in the hopper it is impossible to load soft or bushy items. With the bolts installed in the end of the discharge chute and with the mulcher turned to point straight down, the chute either blocks up or you are constantly having to clear the chippings away. However, with the hopper baffle removed and the chipper/mulcher turned as the adjustment allows and the bolts not installed in the end of the discharge chute, the machine works very well. Just don’t put your hand down the hopper or stick your hand up inside the discharge chute.

  15. Mr David M Moat (verified owner)

    Service was excellent as product arrived next day assembled as ordered. Nothing much to do other than check oil level ( was slightly overfilled) and add fuel. Engine started on first pull.

    Bought the FM6DD What an amazing bit of kit, Glad I did my homework, This is the only one to buy 100 Stars

  18. Gerard (verified owner)

    great, super

  19. John Foster (verified owner)

    Bit apprehensive about putting it all together but it was simpler than I thought – it helps to read the instructions and use the phone! I needed to make another call to find out how to rotate the chutes – such a simple fix, I wonder why it wasn’t mentioned in the instructions. Did my first big clear up today and found there is a definite knack to feeding the stuff in – less is the key , the mulcher likes long stemmed stuff and doesn’t like being stuffed full. But by and large a joy to use.

  20. Dayne Bendle

    Bought this little thing after much deliberation. Very good price of equipment. Have only used once so far but it demolished all I had thrown at it! Mostly hazel, poplar and beech clippings and a few sunflowers.
    Such small chippings as well, will compost very quickly indeed. Will take 2cm wood if fed in carefully.
    I am going to build a stand for it so I can chip into a bucket instead of onto the floor, Perhaps this is something forest master could also think about making, and also could Do with a handle for moving around.
    Very pleased overall
    (Also price is plus VAT people)

    Great bit of kit👍

  22. Ingo S. (verified owner)

    Very fast overnight delivery. Staff helpful. Easy to assemble and starts on first pull. Shreds and mulches very eavenly.

  23. Simon Peat (verified owner)

    Arrived on time and does the job as stated in the spec. Starts easily and makes short work of smaller branches – I’d say up about 2-3 cm.

  24. phil (verified owner)

    Assembled without difficulty in less than an hour, however, a video of one being assembled would have been a bonus. Slightly fiddly to fill with oil without spilling some so care needed. Started on 2nd pull, works great. Demolished a large pile of hazel branches with ease but slowed a bit pulling the leaves through. Quite a laborious job dealing with walnut branches as they were too irregular for the infeed and required trimming.
    I stood the machine on a pallet a fed the chips into a garden bag which worked great.

  25. Dean Jordan (verified owner)

    Had to tweak it to get it to do what I wanted it to do. I suppose it no longer conforms to safety regulations.

  26. Ian Reeves (verified owner)

  27. Keith Jackson (verified owner)

    In keeping with other reviews of this product it desperately needs a handle to manoeuvre it. The product is very much handicapped by the e.u. plate and the requirement to keep the outlet to a max of 30mm from the ground. This makes it almost impossible to mulch as it quickly blocks. Like others I found that discarding this requirement changes the product from one that is virtually not fit for purpose to one that is eminently suitable. It could however do with a quick release mechanism on the hopper and the outlet pipe to quickly resolve any blockages that may occur. It starts first or second pull and its small footprint is a boon for storage. Subject to the above I would recommend it.

  28. Mike J. (verified owner)

    Brilliant bit of kit. It chewed through a mass of branches and leaves in a very short time.

  29. Stephen M. (verified owner)

    Cracking bit of kit, fast delivery, does exactly what it says on the tin.

  30. Jesse (verified owner)

    Although the forest master chipper wasn’t the right tool for me or the work I do. I found the customer service great and they were happy to help. I’d used the machine and realised that in the future I will need something larger for the work I want it to do. They arranged for collection and refunded me within a matter of days. considering I had used the machine and I had to pay the postage back. I think the amount I received back was more than fair. Over all a very professional customer service.

    We have not received it yet, so it is difficult to pass judgement.

    fast delivery, well packed. easy to assemble. Only minor comment I think the output chute is too close to the ground, and clogs easily.

Q & A

With the chipper accessory, is this mulcher able to tackle branches larger than 10mm? or do I need the chipper? Richard asked on October 10, 2021
Hi Richard, the chipper/mulcher is capable of chipping branches up to 50mm, no matter which chute is attached. The 10mm figure comes from the material which is produced after chipping. Forest Master answered on October 11, 2021 store managerstore manager
