Two cylinders in one machine, and only one of them scarifies · review
Thirty-two free-swinging blades on a 182 cm³ four-stroke, with a depth range that stops at ground level and an easy-start engine.
The bottom line The only machine here with free-swinging blades — thirty-two of them — which give way when they meet a stone instead of stopping the machine. The depth range runs from −15 mm to zero and no higher, which says plainly that this is a scarifier rather than a rake. 40 cm, 182 cm³, 40-litre catcher.
A petrol scarifier for larger gardens with a 182 cm³ four-stroke engine, 32 free-swinging blades and a 40 cm working width, for efficient scarifying and aerating of the soil. The working depth is adjustable from −15 to 0 mm. The 40-litre catcher holds the debris. The engine is described as easy-start and the machine as suited to large lawns and rough terrain.
Thirty-two blades hinged rather than bolted. When one meets a stone it swings back; when the obstruction has passed, centrifugal force returns it.
Every other scarifier on this shelf has fixed blades on a roller, which cut consistently and stop hard on something buried. On a lawn that has had builders on it, or one on stony ground, that difference is the machine’s working life.
It is also why the count is higher here: a swinging blade cuts a narrower slot than a fixed one, so more of them are needed for the same coverage.
−15 to 0 mm. Nothing above ground level.
Other machines here offer +5 or +6 mm, which on a bladed roller means the blades are skimming the surface and doing very little. Those machines have a sprung cartridge for that job; this one does not, and the scale reflects it honestly rather than padding the range.
One blade every 1.25 cm, the closest spacing in the family — against one every 2 cm on the electric machines and one every 2.7 cm on the other petrol one.
Closer means more lines cut per pass and more resistance, which is what the engine is for.
Any aerating roller. The weight. And the catcher, at 40 litres on a 40 cm machine, is small for the rate at which this one will fill it.
From 509 € to 717 €, 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.

A blade hinged on the shaft rather than fixed to it, so that when it meets a stone or a root it folds back instead of transmitting the shock. It is the same principle as a flail, and on rough ground it is the difference between a deflection and a repair.
Because above ground level a bladed roller is not doing anything useful — combing is a job for sprung tines, and this machine has none. Stopping the scale at zero is an accurate description of what the machine is for.
Closer spacing cuts more lines per pass, which is more thorough and takes more power. On a 182 cm³ engine that is a reasonable pairing; the same spacing on a small electric machine would bog.
A large, stony or rough lawn where a fixed blade would find something hard
