Restore compacted, moss-heavy grass with the Vonhaus 1800W scarifier. Designed to lift moss, clear thatch, and remove the build-up that mowing can't reach, this lawn scarifier helps air, water, and nutrients move more freely through the soil where the grass needs it most.

With an 1800W motor, 38cm working width, and 55L collection bag, it's built for medium to large lawns over 300m². Two interchangeable drums let you switch between lighter raking and deeper scarifying, while five depth settings help you match the treatment to your lawn's condition.

Lawn scarifier and aerator for healthier grass

A lawn can look freshly mown and still struggle underneath. Moss, thatch, and dead grass gather at the base, forming a dense layer that blocks moisture, air, and nutrients from reaching the roots properly.

This lawn scarifier and aerator helps clear that layer, giving grass a better chance to recover and grow more evenly. Used at the right time of year, it can make the lawn feel less spongy underfoot and encourage stronger growth from the roots up. Mowing keeps the surface tidy; scarifying improves what's happening below it.

Electric lawn rake for moss, thatch, and surface debris

Two interchangeable drums give this electric lawn rake more range than a single function scarifier.

The raking drum lifts surface moss, loose grass, and garden debris – the right choice for lighter seasonal maintenance when the lawn needs tidying rather than deep treatment. Switch to the scarifying drum when the grass needs more intensive care, working deeper to pull out stubborn thatch and open up the surface for better airflow and absorption.

Moss remover for lawns that need more than a mow

Moss takes hold quickly in shaded, damp, or compacted lawns. Left alone, it competes with grass and makes it harder for the lawn to recover evenly between seasons.

Used as a moss remover, this garden scarifier lifts moss and thatch in one pass, collecting debris as you go. That makes it easy to reset the lawn before feeding, overseeding, or returning to regular mowing.

Five depth settings for the right level of treatment

Scarifying works best when the depth matches the condition of the lawn. Go too light and you may not shift enough thatch. Go too deep too soon and you risk stressing the grass before it can recover.

Five depth settings run from -12mm to +6mm moving from gentle surface raking to deeper scarifying depending on what the lawn needs. Start higher for lighter maintenance or a seasonal tidy, and work lower when the grass is more compacted or overdue a proper clear-out.

1800W garden scarifier for medium to large lawns

Running at 3,500RPM, the 1800W motor works through thicker moss and thatch without losing pace. The 38cm working width covers more ground with each pass, making it ideal for medium to large lawns over 300m² where a narrower machine would mean significantly more time spent on the job.

A 10m cable gives you good reach across the lawn, while the 55L collection bag reduces the number of stops needed to empty moss, thatch, and debris as you work.

Large 55L collection bag for fewer interruptions

Scarifying can lift a surprising amount from the lawn, especially if it's been left untreated for a while. The 55L collection bag keeps the job moving by catching loose moss and thatch as you work – fewer pauses, less raking afterwards, and a cleaner finish across the lawn. When the bag is full, it lifts out easily for emptying before you carry on.

Comfortable to use, with built-in safety features

A height-adjustable handlebar lets you find a comfortable working position across longer sessions. The two-stage safety trigger prevents accidental starts, and the thermal cut-out protects the motor during extended use, keeping your lawn aerator steady and safe to run across a full garden treatment.
