Lawn aerators
Gardena 3391-20
A galvanised tine head for a modular handle system — the cheapest item here, and the handle is extra.
What this is
A head, not a tool.
It clips and screws onto a handle from the maker’s modular range, which is sold
separately — the listing’s delivery line says so plainly, and it changes the
real price of this item.
On a shelf where everything else arrives complete, that makes the comparison
awkward: this is the cheapest thing here by a wide margin and it is also not a
whole product.
The modular trade
Buy into a range like this and the first tool is expensive, because you are
buying a handle as well. The tenth is cheap, because you are not.
The listing names the other side of it too: the head fits all handles in
the range, wood or aluminium, including the longer back-sparing ones. Somebody
who already owns a hoe, a rake and a brush on those handles gets an aerator for
the price of a head, and stores it in a drawer.
Somebody who owns none of them is buying two things.
Cutting tines, not hollow tines
This is the distinction that divides this shelf, and it is worth stating on
every page here.
A cutting or spike tine is solid. It pushes into the sward, slices thatch,
and displaces the soil sideways — which opens the surface and also presses the
walls of the hole outward.
A hollow tine is a tube. It pulls a plug of soil out and leaves it on the
lawn, removing material rather than moving it.
On a compacted soil the second is what relieves compaction. The first opens the
thatch layer, which is a real and useful job — it just is not the same job.
One product on this shelf has hollow tines. This is not it, and the listing is
honest about what it does: it frees the lawn of thatch and moss, and can break
up clods.
What goes unpublished
No width. No tine count. No tine length.
On a hand aerator, tine length is the specification — it is the depth you can
reach and nothing else about the tool changes it. Two products on this shelf
publish one; four, including this, do not.
Availability
From 22 € to 28 €, that being the spread across the German, French 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 Italian 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.
