Lawn Scarifier Buying Guide

The lawn scarifier is a gardening tool that aerates your lawn by cutting through the soil and removing debris. They are more commonly powered by electricity but there are some that are petrol powered or completely manual.

Benefits from scarifying your lawn is that it allows for a better flow of air and water for a more healthier lawn. After you have used the tool, your garden may look worse but after a few days, it will look far better than it ever did.

To help you make an informed buying decision, we have produced the below guide regarding lawn scarifiers.

Petrol vs Electric vs Manual

The majority of scarifiers are electric powered as they require very little maintenance and are fairly cheap. However, for larger gardens where you may not have access to a power supply, the best option would be a petrol lawn scarifier.

Manual alternatives are the cheapest and simplest to use but they are not suitable for medium to large gardens.

Choosing between the three different types is dependent upon the size of your lawn and whether there is a power supply.

2-in-1 – Lawn Raker and Scarifier

Some of the recommendations within this article can act as both a scarifier and a lawn raking. The main difference between the two types is that the scarifier uses blades tines and a lawn rake uses wire tines.

The 2-in-1 lawn raker and scarifiers can be highly beneficial for some gardeners. You are able  to easily switch between the two functions by simply changing the blade.

The Blades

In order to cut through the grass, the scarfier requires durable blades. Most will use a strong metal material and you will want to avoid blades that are made from plastic. Overtime, you may find that they lose their sharpness but most manufacturers will provide replacements.

Working Depth

Depending upon whether you simply want to remove moss and debris or aerate the lawn will determine the working depth you require.

Removing moss, thatch, cut grass and other debris does not require much depth. However, in order to aerate the soil (as shown in the image below), you will certainly require enough depth so that it pierces the soil.

To ensure that you are covered for each situation, a lawn scarifier with adjust height positions would is best type to buy.

Raking Width

For those with medium to large gardens, you will want to have a wider raking width. This will help the scarify process go far more quickly because it can be a long process otherwise. If you have a smaller garden with lots of curves, you will want a smaller width for the best results. Trying to navigate around curves with a large raking width can be fairly difficult.

Collection Box

The purpose of using a lawn scarifier is to remove the debris from the grass. Therefore a collection box that holds all the debris is an essential component.

Depending upon the size of your lawn will determine the appropriate size that you require.

It is important that you choose the right size because too small will result in frequent emptying whereas too big may make it harder to use. The majority of boxes  that attach to a scarifier range from 30 to 60 litres in size.


If something is difficult to use, you are less likely to use it. Therefore, you will want a lawn scarifier that you can simply switch on and get to work. Features to look out for that improve usability include:

  • Lightweight design
  • Ease of changing the height
  • Ergonomic handle with adjustable positions
  • Easy removal of the collection box
  • Ease of replacing the blades

When Should You Begin Scarifying

Choosing the best time to scarify your lawn can make a huge difference. According to Flymo, they state that you should scarify your lawn around March and again at the end of September.

Its advised that you avoid scarifying during the winter months because a thin layer of thatch is actually good for the lawn.

How to use a Lawn Scarifier

Before you begin to scarify your lawn, you should cut the grass with a lawn mower a few weeks beforehand. You will be able to achieve better results scarifying short grass than you would with longer grass because it minimizes the stress on the grass. You can also use a garden vacuum to remove larger debris on the lawn.

To begin scarifying, you will want to set the height of the blade. We recommend choosing a height that is furthest away from the grass to begin with as this will remove the debris. Once complete, you can then lower the blade and begin scarifying the lawn.

Most lawns will require at least two rounds of scarifying for the best results. On the second run, we recommend going in the opposite direction to the first run. This will help with tackle areas of the lawn that were missed.

Once you are finished, it may look like your lawn is ruined but this it just needs time to recover. To help assist the recovery process, you can add a good lawn fertiliser and lightly spray water to help the grass grow back thicker and more quickly.


Lawn scarifiers are mostly purchased by enthusiasts that want to perfect their garden. They essentially cut through the grass to help improve the flow of air and water for a more healthier lawn. There are various different types but the best are usually powered by an electric motor.

All of our recommendations cover electric, petrol and manual scarifiers that all have unique features and are suitable for a range of budgets.
