For medium lawns that need a seasonal reset, the Vonhaus 1500W scarifier does the work that regular mowing leaves undone. Lifting moss, clearing thatch, and removing the compacted build-up that blocks moisture and nutrients from reaching the roots – it's an easy way to give grass a better chance to grow evenly through the season.

With a 1500W motor, 32cm working width, and 30L collection bag, it's well matched to medium lawns between 100–300m². Two interchangeable drums cover lighter raking and deeper scarifying, and four depth settings let you match the treatment to what the lawn needs.

Lawn scarifier and aerator for healthier grass

Regular mowing keeps things tidy on the surface, but it doesn't reach the layer of moss, thatch, and dead grass that builds up at the base of the lawn over time. That layer is what makes grass feel spongy underfoot and struggle to grow back evenly after cutting.

This lawn scarifier and aerator breaks through it, clearing the debris, opening up the soil, and giving air, water, and nutrients a clearer path to the roots. The difference is most noticeable a few weeks after treatment, when the grass starts to fill in more evenly and the lawn feels firmer underfoot.

Electric lawn rake for moss, thatch, and surface debris

The two interchangeable drums are what make this more useful than a standard scarifier. Rather than committing to one level of treatment, you can choose the right drum for what the lawn needs that day.

The raking drum works across the surface – lifting loose moss, dead grass, and seasonal debris without disturbing the soil beneath. It's the right starting point for lawns that need a tidy rather than a full treatment. The scarifying drum goes deeper, pulling out stubborn thatch and helping the soil breathe more freely. Between the two, most lawn conditions are covered without needing separate machines.

Four 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.

Four depth settings run from -12mm to +4mm 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.

30L collection bag for fewer interruptions

The 30L bag is well sized for medium lawns (100–300m²), providing enough capacity to work through a good portion of the garden before stopping to empty it.

Scarifying pulls up more than you might expect, especially on lawns that haven't been treated for a season or two. So, having a bag that keeps pace with the job makes a noticeable difference to how long the process takes. When it's full, it lifts out cleanly and reattaches easily before you carry on.

Comfortable to use, with built-in safety features

At 9.9kg, this lawn aerator is light enough to manoeuvre comfortably across a medium lawn without the machine feeling like the effort. The height-adjustable handlebar helps you settle into a comfortable working position, and the two-stage safety trigger means there's no risk of an accidental start mid-session. A thermal cut-out protects the motor during longer treatments, so you can work through the full lawn without having to stop and let it cool down.
