Best Lawn Scarifier – Buyer’s Guide

Whether you’re repairing an existing lawn or trying to keep your grass looking green and healthy all year round, a scarifier is an essential tool to help you achieve your gardening goals.

However, there are a few things you need to give some thought to before making your purchase in order to make sure you get the perfect lawn scarifier for your needs. We’ve outlined some key points below for you to bear in mind when you’re shopping around.

Power

The first thing you need to think about is how much power you need from your lawn scarifier, and how you intend on supplying it with power as well.

Let’s start with the wattage that you require. Removing unwanted growth such as moss and thatch from your lawn, whilst ensuring you don’t accidentally cause any damage to the existing grass, requires a fair amount of force, so you’ll need a scarifier with a decent amount of wattage to it.

The amount of wattage to go for, however, can usually be determined by the size of your lawn. If you have a smaller or medium sized lawn, then a scarifier that has somewhere between 600W and 1000W of power will be adequate for a smaller area. If you have a large garden then you should choose a model that has around 1000W to 1500W of power.

The next thing you need to think about is what source of power is best for you. Scarifiers and lawn rakers are available with motors that are either powered by electricity or petrol, and your choice between these will usually also come down to the size of your garden.

Electric scarifiers are a good choice for smaller and medium sized gardens, as you’re more likely to have closer access to an electrical outlet. They also tend to have power cables that are around 10m-12m in length, which allows you to move freely around your lawn without needing to use an extension lead.

If you’ve got a larger garden, then a petrol scarifier may be the best option as you’ll be able to move freely around a large amount of lawn without needing to plug in multiple extension cords in order to cover the entire area. Bear in mind, however, that you will need to have a ready supply of petrol available to you in order to prevent the scarifier from cutting out on you as the tank empties.

Blades

The purpose of scarifying a lawn is to remove unwanted growth, allowing your grass to take up more nutrients, prevent the soil from becoming compacted over winter, and to prepare the ground for reseeding in spring or autumn. With this in mind, you need to make sure that the scarifier you choose has all the correct blades or attachments in order to carry out all of these tasks effectively.

Most scarifiers contain blades and tines that are able to do all of this thanks to their powerful, sharp blades. However, there are some models available that allow you to switch and interchange between raking and aerating blades rather than relying on a ‘one size does all’ approach.

These interchangeable blades are great for giving you peace of mind that you’re carrying out the exact task you set out to do, and also give you the opportunity to remove and clean the blades as necessary. They are also usually easy to remove without the need for any additional tools, allowing you to quickly switch between them without any hassle.

Cutting Height

Whilst most people only really think about dethatching their lawns and preparing the ground for reseeding at certain times of year, it’s actually really important to ensure that you’re maintaining the health of your grass all year round.

One way to make sure you’re doing this is to look for a scarifier that comes with different cutting height options. This will allow you to get as close to the ground as possible whilst the grass is cut shorter during the spring and summer (and when moss and thatch is most actively growing), and will allow you to aerate the soil when the grass is longer during the winter, making sure that the ground doesn’t become compacted through rain, snow and ice.

Collection Bag

A good lawn scarifier will also come complete with a collection bag, which will pick up and store any unwanted growth you’re removing from your lawn, without it falling back to the ground or requiring you to manually rake it all up afterwards.
When you’re looking at your potential lawn scarifier’s collection bag, make sure that it has a capacity that matches the size of your garden. Anything too small and you’ll find yourself constantly stopping to empty it out onto your compost heap, resulting in the job taking twice as long as it needs to.

There are some scarifiers that come with collection bags that have been designed to compact the clippings as they collect them. These are a good choice for larger gardens, as they’ll be able to fit much more into them without you stopping to empty it.

Another thing you’ll want to make sure of when you’re looking at the collection bag is that it is easy to remove from the scarifier for emptying, and that you can easily clean it in order to keep it in good condition.

Safety Features

A scarifier is a potentially dangerous piece of gardening equipment, so it’s important to make sure there are some safety measures in place to keep you protected from any accidents or injuries.

One really good safety feature you’ll find one some scarifiers is the power cutting out as soon as you let go of the handle. This means that there is no chance of the machine getting away from you if you lose your grip, and also means that you don’t have to worry about fully switching it off every time you need to empty the collection bag.

Another fantastic safety feature is an integrated cord holder, which will help you make sure that the electrical cable is kept secure and prevents you from accidentally running over it as you move around your lawn.

Storage

Finally, you should give some consideration to how you intend on storing your scarifier when it’s not in use, and how much space you have in order to keep it neatly stashed away until you’re ready to use it again.

One good feature to look out for here is a foldable handle. This will allow you to totally remove the height of the scarifier, so you’ll be able to compactly store it underneath a work surface in your shed or neatly lean it up against the inside wall of your chosen storage area without it taking up a huge chunk of space.

Frequently Asked Questions

What’s the difference between lawn raking and lawn scarifying?

Lawn scarifying is a generic term that is used to describe a lot of different lawn care techniques, including lawn raking. There isn’t really a difference between the two, as one element of lawn scarifying is raking up unwanted moss growth in order to let your grass take up more nutrients and grow healthily. Scarifying a lawn also includes aerating the soil and preparing the ground ahead of sowing new grass seed.
