Lawn rakers and scarifiers on test

To see which lawn rakers and scarifiers will leave your garden looking pristine, we tested some over the course of several months.

In total, we tested eight electric machines: three for raking only, and five that rake and scarify. At our test site, our grass experts used each machine on two lawns. One had a build-up of thatch and debris, while the other was mossy and treated with a lawn mosskiller before the test started. We recorded the time it took to cover each test site, weighed the material removed, and rated the machines effectiveness.

How we test lawn rakers and scarifiers

For each lawn raker and scarifier we test, we pay close attention to the features that matter the most, to ensure you get good value for money.

To help us highlight the best lawn rakers and scarifiers money can buy, we paid close attention to each of the following:

  • Speed - How quickly the machines can pull moss or thatch from turf
  • Effectiveness - How much moss or thatch was removed and how well it was collected
  • Short-term effects - How free from moss and thatch the grass looked
  • Long-term effects - How dense and healthy the grass grew
  • Convenience - How easy the machine is to move and operate
