BRAST BRE-RV-4000 review

A 2000 W machine with a stated depth range of −12 to +6 mm, a 55-litre bag and both rollers — sold as one of three models in a range.

The bottom line Publishes the figure most of this shelf omits: a working depth of −12 to +6 mm in five central steps, with ground level at zero. A 40 cm width on 2000 W, twenty blades and twenty-four tines on interchangeable rollers, a 55-litre bag, and both wheel diameters given.

What the maker prints on its own page

An electric scarifier with a 2000 W motor on a 230 V / 50 Hz supply and a 40 cm working width, stated as suitable for lawns up to 1000 m² and awarded a mark by a German consumer test body. Scarifying and aerating are combined through easily interchangeable rollers: a scarifying roller with 20 sharp blades and an aerating roller with 24 tines. The working depth is set centrally in five steps from −12 mm to +6 mm. The handle is ergonomic, rubberised, height-adjustable and folds. The bag holds 55 litres. Front wheels are 180 mm and rear wheels 150 mm, and a cable strain relief is fitted.

The listing covers three models between 1050 and 2000 watts and 32 to 40 cm.

The scale that matters

−12 to +6 mm. Zero is the ground.

That is how a scarifier is actually set, and it is the specification this shelf most often omits. Above zero the machine combs the surface, which is useful on a lawn matted with clippings and useless on one with thatch. Below zero the blades cut into the layer, and 10 to 15 mm below is where the operation does its work.

Too deep and the machine is cutting into soil and tearing roots. A published range is what lets a buyer know the machine can be set correctly at all.

Three models in one listing

Width and wattage both depend on which variant is selected. This page reports the figures the listing leads with and states the ranges — a comparison built on the top of a range would describe a machine nobody is buying at that price.

The 1000 m²

A positioning figure. A mains machine has no energy budget to exhaust, so nothing limits it but your patience and the cable.

On a scarifier specifically that is worth saying, because the operation is slow: overlapping passes, a full bag every few minutes, and a lawn that has to be raked afterwards.

Availability

From 130 € to 180 €, that being the spread across the German and French Amazon stores on the day of the survey.

Listed and unsold: the British, Italian and Spanish Amazon catalogues hold the reference with nobody behind it.

Nothing came back from the American Amazon store at all; the buy button there runs a search rather than opening an empty page.

The declared figures, and the point they stop at

Strengths

  • A published depth range with ground level at zero — the figure that decides the job
  • A 55-litre bag, the largest on this shelf alongside two others
  • Wheel diameters given front and rear, and a cable strain relief stated

Compromises

  • The listing covers three models at once, so width and wattage depend on the variant chosen
  • The 1000 m² is a positioning figure rather than a limit on a mains machine
  • No weight published

What this machine usually gets asked

What does −12 mm mean?

Twelve millimetres below ground level — the blades cutting down into the thatch layer rather than combing above it. Zero is the surface and +6 mm is above it. That scale is the whole of scarifier setting, and only four listings on this shelf publish it.

Which model is this, exactly?

The listing describes a family: 1050 to 2000 watts and 32 to 40 cm across three models. This page reports the figures for the variant the listing leads with, and prints the range as a range — picking the top of it would describe a machine that is not at the stated price.

Is a bag better than a box?

A bag folds flat for storage and is lighter to carry; a rigid box rinses out and holds its shape when full. On a scarifier the bag clogs with wet thatch either way, and the emptying is the job.

Who this one is for

A large lawn with real thatch, where the depth needs setting rather than guessing
