AL-KO Razor Cut 38.1 HM Comfort review

The widest cylinder mower here at 38 cm and the only published weight — 7.7 kg — with non-contact cutting and 22 cm wheels.

The bottom line The widest and the lightest at once: 38 cm and 7.7 kg, the only weight published on this shelf. The cutting is non-contact — the cylinder and the bottom blade never touch — which is what makes a cylinder mower stay sharp instead of grinding itself. Large 22 cm wheels and a rubber bumper.

What the maker prints on its own page

A cylinder mower with non-contact cutting technology — the maker states that the cutting cylinder and the bottom blade do not touch — giving a perfectly cut lawn. The low weight of 7.7 kg and the compact build allow comfortable, flexible work. Operation is emission-free and quiet, with no exhaust and no energy consumption, and the maker notes that it can therefore be used at any hour. The wheels are 22 cm for pushing comfort and a rubber bumper protects against knocks and scratches. The cutting height adjusts in four steps and the maker states the machine suits lawns up to 250 m².

Non-contact, and why it is in the first line

On a contact cylinder mower the spiral rubs the fixed blade, which cuts well and wears both surfaces. On a non-contact design they pass with a clearance, and the cutting comes from the geometry rather than the rubbing.

The consequence a buyer feels is sharpening: a contact machine needs its blades taken back regularly, and a non-contact one holds its edge far longer. The consequence a buyer does not feel until it goes wrong is setting — a clearance that has drifted stops cutting cleanly and has to be reset.

Widest and lightest

38 cm on 7.7 kg is an unusual pairing and the listing is right to lead with it. Width and weight normally rise together; here the extra width comes with the lowest mass on the shelf.

What that does not remove is the cutting load. A wider cylinder takes more grass per turn, so the effort at the handle rises with width regardless of what the machine weighs.

The 250 m²

The largest stated area on this shelf, and, like the others, a positioning figure rather than a limit — the machine has nothing to run out of.

For a hand-pushed mower the real constraint is how often you are willing to do it. A cylinder mower on 250 m² is a regular commitment, not an occasional one.

What is not there

The height range, which on a cylinder machine is the specification that decides whether it suits your lawn at all. And no catcher volume.

Availability

From 70 € to 106 €, that being the spread across the German, Italian and Spanish Amazon stores on the day of the survey.

Beyond the euro zone, the American and British Amazon stores price it in their own currencies, which the spread above sets aside.

More than 1.6× the cheapest country at the French Amazon store; a gap of that size normally means forwarded stock rather than a seller on the ground, so the spread above leaves it out.

Compromises

  • No cutting-height range at all, only the number of steps
  • No catcher volume — the listing does not confirm a box is supplied
  • The widest cylinder is the hardest to push through anything but short grass

What this machine usually gets asked

What is non-contact cutting?

The cylinder passes the fixed bottom blade with a small clearance instead of rubbing against it. A contact design cuts by shearing against the blade and slowly grinds both; a non-contact one relies on the blade geometry and stays sharp far longer. The trade is that it needs setting accurately.

Does 38 cm make it hard work?

Wider is more grass per pass and more resistance at the handle. At 7.7 kg the machine itself is light; what you feel is the cutting load, which rises with width and with how long the grass has been left.

Is a grass box included?

The listing does not say. On this shelf a box is usually supplied or offered, and this page does not assume either way — what it records is that the contents are unstated.

Who this one is for

A larger small lawn — up to a couple of hundred square metres — kept genuinely short
