Electric Shredder Mulcher for Wood branches, Plants and Garden Waste (FM4DDE-MUL)

3-in-1 Compact Electric Wood Chipper, Garden Shredder, and Mulcher - Forest Master FM4DDE-MUL

Mulching and composting just got a whole lot easier and more effective with our patented (GB2100107.8) 4HP Electric Shredder Mulcher.

New August 2022 Design Update: We’re always striving to improve our machines to make them the best they can be and to meet our customer’s high expectations which we’ve built over decades of forestry experience.  Our August 2022 update features a newly designed exit chute which combats and prevents blockages when mulching and chipping.

Compact, Lightweight, Powerful and Robust are the best words to describe our brand-new and innovative machine. The first of its kind, the electric shredder mulcher is capable of intaking any waste you can throw at it and processing it into precious mulch, crucial in creating effective black gold (compost) for your garden. 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. Our mulcher has been stress tested with anything you can think of and it’s yet to meet garden waste it can’t handle. Wood older than three days may produce sawdust.

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 FM4DDE-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.

How is the FM4DDE-MUL Electric Garden Shredder, Mulcher and Chipper better than competitors? Well, our machine is designed and produced using a steel design. You’ll find that the majority of garden shredders available on the market feature a plastic design. Why is steel better than 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 a petrol engine? not a problem! We also have a full range of petrol mulchers on their way – ranging from 6HP right the way up to a massive 18HP.

Want to learn how to put this machine to the best use? Check out our gardening category within our blog and find out everything you need to know about creating compost. 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.

  1. Easy to put together, well made and sturdy and works a dream, no more trips to the tip spending time bagging garden trimmings. Makes great mulch for the garden. Wish I’d had one years ago.

  3. Assemly instructions could be updated, e g star washers replaced with self tightening nuts on the main engine bolts. Had to just angle of shoot to fix extract shoot.

  4. This mulcher works really well, handles green material really well with no clogging or jamming. First cuttings I put through it was cherry laurel, the large waxy leaves were no problem. I’ve also fed branches in up to the max 50mm and it worked really well. My only comment would be to supply the machine with a longer mains flex, at least 5m, or preferably the max 10m. This is a expensive item, so the 1.5m cable as supplied seems a little unreasonable, and completely impractical. I would thoroughly recommend the product in every other regard, and the company provided an excellent service.

Was ist der Unterschied zwischen der EU- und der UK-Version? Nur der Stecker? C. Dietrich asked on June 2, 2023

Die EU-Ausgabe des FM4DDE-MUL bietet erhöhte Leistung und ist mit einem EU-Stecker ausgestattet. Darüber hinaus verfügt es über eine 13-Ampere-Abschaltung, während die britische Version mit einer 10-Ampere-Abschaltung ausgestattet ist. Dieser Unterschied ermöglicht es der EU-Version, eine größere Materialaufnahme zu bewältigen, ohne die Maschine zu überlasten.

What's the difference between this machine and the Compact Electric Wood Chipper 4hp Direct Drive FM4DDE? Is the latter also good for mulching and shredding cardboard? Thanks Guilherme Pires asked on November 4, 2022

The primary difference between the two machines is the type of material they can process. If you're looking to chip tree branches or cuttings with few leaves then the chipper will be perfect for you. If you're looking to chip, shred and mulch leafy hedges and green material such as vegetable matter then the mulcher is better suited for you.

Both machines are capable of chipping the same diameter wood, 50mm (2 inches).
