Rank #5 in Best Lawn Scarifier 2026: 10 Ranked, and the 36V Trap
Einhell 36V (2 x 18V) Cordless Scarifier — Bare Tool
Price and rating as shown on Amazon when we collected them. Both change.
The Einhell Cordless Lawn Scarifier and Aerator takes fifth place in this guide, and its own name carries the first warning: "Without Battery". The 36V in the title is two 18V PXC batteries added together rather than one 36V pack, and the listing's own bullet states the tool "requires 2 x 18v Lithium-ion rechargeable batteries and charger (sold separately)". At £164.99, that means the money buys the bare scarifier, a 28L collection basket, one blade roller and one fan roller.
The same listing then quotes a battery average life of 90 minutes, which is a runtime for batteries it does not include. One bullet also describes a "28 cm long suction nozzle" with a rubber lip for streak-free cleaning, wording that does not describe a scarifier at all. What the machine does state is a 35 cm cutting width, three working depth adjustments between 1 cm and 3 cm, and 11.3 kg. Everything on this page is taken from the Amazon listing, not from testing we carried out ourselves.

Questions people ask
Does the £164.99 Einhell scarifier come with a battery?
No. The listing states the tool "requires 2 x 18v Lithium-ion rechargeable batteries and charger (sold separately)", so that price buys the bare tool.
Why is it called 36V if it uses 18V batteries?
The Einhell 3420685 runs on two 18V PXC batteries, so the 36V figure is the sum of the two rather than the voltage of any single battery.
What does the listing claim for runtime?
The specification line gives a battery average life of 90 minutes, even though no battery is supplied with the tool.
What is in the box?
Included components are listed as the cordless scarifier, a 28L collection basket, one blade roller and one fan roller.
How wide is the cut and how deep will it go?
Cutting width is 35 cm, with three working depth adjustments covering 1 cm to 3 cm.
How heavy is the Einhell 3420685?
Item weight is listed as 11.3 kg, while the "Unit Count" field in the same listing reads 11.31 kilograms.
