Forest Master FM4DDE review

A 38 kg mains machine taking 50 mm wood, with a hopper and chute that hinge open for maintenance.

The bottom line A mains machine built like a petrol one: 38 kg, 50 mm wood, and a hopper and discharge chute that hinge open so the inside can be reached without dismantling it. That last feature is the one nobody else offers and the one that decides whether a shredder is still working in five years.

What the maker prints on its own page

Chips wood up to a diameter of 50 mm (2 inches). A 4 PS 2800 watt electric motor running on the household supply. Compact for easy storage at 820 mm long, 780 mm high and 470 mm wide, described as approximate. A hinged hopper and discharge chute for easy maintenance. A light weight of only 38 kg.

The hinge

Five words in a feature list, and the most valuable thing on this page.

A garden shredder’s interior fills with wet, matted, fibrous material. Blades blunt. Something metallic goes in eventually. On most machines on this shelf the answer to all three is a set of bolts, a workbench and an afternoon — which in practice means the machine is used until it jams badly and then replaced.

A hopper and chute that hinge open turn all of that into a two-minute job. It is the difference between a tool that is serviced and one that is thrown away.

Weight and dimensions, both stated

38 kg, and 820 × 470 × 780 mm.

Two machines on this shelf give a weight and both of them are unusual: this one because it is an electric machine built to petrol proportions, and the other because it is a 75 kg freight item.

The rest give nothing, and a buyer of any shredder should want to know whether the thing arriving fits in the shed and can be moved to the hedge.

What “4 PS” means on an electric motor

The listing gives both 2800 watts and 4 PS for the same motor. They are the same figure in two conventions, and this site prints both because the maker did.

The watt figure is what the machine draws from the socket. It is not what arrives at the cutter, and on this shelf it is the only power number most listings give.

What is not there

The cutting system. On a shelf where the blade-or-roller question decides the chip, the noise and the material the machine suits, this listing does not say which it is.

No bag, no box, no reduction ratio.

Availability

From 650 € to 1012 €, that being the spread across the German, French, Italian and Spanish Amazon stores on the day of the survey.

Beyond the euro zone, the British Amazon store prices it in its own currency, which the spread above sets aside.

Listed and unsold: the American Amazon catalogue holds the reference with nobody behind it.

The declared figures, and the point they stop at

Strengths

  • A hopper and chute that open for maintenance — unique on this shelf
  • A published weight and published dimensions, which only two machines here give
  • Mains powered at a weight and capacity that is otherwise petrol territory

Compromises

  • The cutting system is not named — blade or roller is unstated
  • No collection bag or box, and no reduction ratio
  • The most expensive mains machine on the shelf by a wide margin

What this machine usually gets asked

Why does a hinged hopper matter?

Because a shredder’s inside fills with damp, matted material and eventually needs cleaning, and because blades need reaching to sharpen or replace. A machine you can open is a machine you can maintain; one you cannot is disposable at the first serious jam.

Is 38 kg heavy for a mains machine?

It is the heaviest electric machine here by a wide margin — the others do not publish weights, but they are parcel-sized. Thirty-eight kilograms is roughly half a petrol machine and is one person’s lift with care.

Blade or roller?

The listing does not say, and this page does not guess. On this shelf that is the first question, because the two types produce different chips, make different amounts of noise and suit different material.

Who this one is for

Regular woody shredding on a property with a socket, by somebody who expects to maintain the machine
