Scarifier blades
Oregon 690-617-0
A 41 cm power-rake bar sold by its dimension rather than by a machine list — three lines of listing and one figure.
What the maker prints on its own page
Three lines: a scarifier blade bar, a de-mosser, 41 cm.
That is the listing in full.
Sold by a dimension
On a shelf where the usual pattern is a length plus a list of machine names,
this is the opposite: a length, and nothing else.
That is less useful than a full dimension set and more useful than a
compatibility list, because a dimension is a fact about the object and a list
is a claim about a catalogue.
What it means in practice: measure your existing blade or bar. Length first,
then the shape and size of the centre mount, then whether it locates on pins
and at what spacing. This listing answers the first of those three.
What this article is
A bar that replaces a mower’s ordinary blade and turns the machine into a
scarifier for an afternoon.
That is a genuinely different product from the replacement roller for a
dedicated scarifier — which is also on this shelf — and German listings use
overlapping words for both. This site separates them and says which each one
is.
The conversion works on machines with enough torque to drag a row of blades
through turf, which in practice means petrol. One listing on this shelf says
so explicitly and this one does not.
The damaged title
The source record carries broken characters where two German umlauts belong.
This page reproduces the title as published. A repaired title is not the title
the listing carries, and on a site whose whole method is reporting what makers
actually print, quietly fixing their text is the wrong instinct.
What is not there
The blade count, the material, the centre mount, the thickness, and any
statement of which machines it suits.
Two listings on this shelf publish a full dimension set. This is the cheapest
one and it publishes one number.
Availability
From 18 € to 24 €, 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.
Taken from Keepa on the day this page was last revised; stock and prices move without notice.
