WALTER 20V Hand Mower review

The only machine in this family that publishes a runtime and a charge time — 20 to 25 minutes, 60 to 90 to recharge — on a light three-step deck.

The bottom line The one listing on this shelf that gives a runtime: 20 to 25 minutes on the supplied 2.0 Ah pack, 60 to 90 minutes to recharge. That is a manufacturer’s bench figure like any other, and it is still more than the other eight offer. A light machine with a swivelling handle, three cutting heights and no stated cutting width.

What the maker prints on its own page

A cordless hand mower on a 20 V platform with a brushless motor. The cutting height adjusts in three steps between 25 and 48 mm. The handle swivels and the build is described as light, for reaching under shrubs and benches. The supplied 20 V 2.0 Ah lithium-ion pack is stated to give about 20 to 25 minutes of running and to charge fully in 60 to 90 minutes. A starting lock prevents unintended operation.

The figures nobody else prints

A runtime and a charge time. Across the whole cordless shelf on this site, this is the only listing that states either.

Both are bench figures. A runtime is pack energy divided by the load, and the load is grass — its length, its moisture, the height you cut at and how sharp the blade is. The conditions behind 20 to 25 minutes are not published, and the honest reading is “about that, on an easy lawn”.

Still: a stated figure with unstated conditions is more useful than a stated area, which is the same arithmetic with the conditions hidden one layer deeper.

The pack, in the unit that compares

20 V × 2.0 Ah is roughly 40 watt-hours. That is the smallest energy on this shelf by a wide margin — a 40 V machine with two 4.0 Ah packs carries about four times as much — and it is the honest explanation of the runtime.

What is missing

The cutting width. On a mower that is the single dimension that decides how long a lawn takes, and it is nowhere in the listing.

Availability

Around 130 €, read at the German Amazon store on the day of the survey.

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

Nothing came back from the British 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 runtime and a charge time, stated — unique on this shelf
  • A swivelling handle, for working under shrubs and benches
  • A starting lock, stated, so the machine cannot be set going by accident

Compromises

  • No cutting width anywhere in the listing
  • The smallest pack here at 2.0 Ah on 20 V, which is where the 20-minute figure comes from
  • Three height steps, and the top of the range is 48 mm rather than 65 or 75

What this machine usually gets asked

Is 20 to 25 minutes enough?

On short, dry grass that is around the time it takes to cover a small lawn, and it is a bench figure obtained under the easiest conditions a maker can claim. A first cut of the season, or wet grass, will be substantially less — runtime is pack energy divided by the load, and the load is your lawn.

How much energy is in the pack?

20 V at 2.0 Ah is about 40 watt-hours. That is the figure to compare across platforms; amp-hours alone cannot be compared between a 20 V machine and a 40 V one.

What does the swivelling handle do?

It lets the machine be pushed at an angle to the operator, which is how you reach under a bench or a shrub without kneeling. On a small machine that is a genuine function rather than a feature line.

Who this one is for

A very small lawn, or the awkward strips a larger machine cannot reach
