Water the lawn: Water the lawn thoroughly a day or two before using the scarifier to soften the soil and make it easier for the scarifier to penetrate the ground.

Manual: As its clear from the name, such scarifiers does not have any power source. Instead, such a machine seeks your muscle power to mover over a lawn and cut through the thatches. They are available in affordable price ranges but are good only for small lawns. So, you can consider one of these tools for any yard up to 100 m2. Blade Type: The blade type is also an important consideration. There are two main types of blades - fixed and floating. Fixed blades are more aggressive and better suited for heavily thatched lawns while floating blades are gentler and better suited for lawns with a light thatch layer. Some scarifiers have adjustable blade height, allowing you to choose the right setting for your lawn. In other words, scarifying promotes the health of your lawn resulting in green and attractive grasses. These are the reason why a lawn scarifier is crucial to maintain your land. We recommend that you scarify your lawn once a year, but you should follow the process only after its two or three years old. Electric corded scarifiers: Lightweight, quiet and often at the budget-end, this type of scarifier is best suited to small and medium-sized gardens with a power supply. Most models come with a collection box, which is a useful, time-saving feature, but the cord length can be restrictive as well as potentially hazardous. Being an electric scarifier, you can start the device instantly by pushing a button. Similarly, it comes with a safety switch that prevents accidental starting. On the downside, it's corded, which limits movement during operation. It weighs 12.25 kg and is built with alloy steel for enhanced durability. Pros:September and October are a great time for dethatching cool-season grasses, whereas warm-season grasses should be dethatched at the end of the spring. In addition to scarification, you need to aerate your lawn. This is a different process that involves removing the cores of the soil and the thatch layer. This creates paths for nutrients and water to penetrate the soil and thatch, which, among other things, makes thatch removal easier. Why do you need a lawn scarifier? Safety is a top priority, and this scarifier delivers with its double safety switch that prevents any sudden start-ups, providing peace of mind during operation.

Manual rolling drum – ideally you want a good number of metal spikes on the drum to create plenty of holes – as a guide, 27 spikes will give you about 180 spikes per square metre. The spikes should also be at least 5cm long to ensure they penetrate the ground deeply. Electric corded aerators: Lightweight, quiet and often at the budget-end, these are best suited to small and medium-sized gardens with a power supply. Most come with a collection box, which is a useful, time-saving feature, but the cord length can be restrictive as well as potentially hazardous. Grass Bag - The Makita UV3600 comes with a 40 litre grass collection bag. The bag is large to minimise the number of times it needs emptying, therefore letting you scarify for longer without interruption. Note that the rear flap angle allows for use without the grass bag. Cobra S3840V has a working width of 38 cm. All thanks to its powerful Lithium-ion battery, it works for up to 35 minutes; depending upon the lawn conditions.

Electric Scarifiers: Powered by electricity, these corded scarifiers are efficient and suitable for medium-sized lawns. They often come with adjustable settings for depth and can be more convenient than manual options.

Cordless scarifiers: Lightweight, quiet and an environmentally-friendly alternative to electric and petrol types, the downside to buying cordless tools is that they can cost more, and the batteries and chargers are sometimes an additional cost. While they don’t have a restrictive cable and are therefore ideal for accessing all areas of the garden, it’s important to be aware of their charge and run times, as this could limit their effectiveness if you have a larger garden. Collection Bag: If you want to collect the thatch as you scarify, look for a model with a collection bag. This can make cleanup easier and prevent thatch from being spread around your lawn. A lot has changed since I first reviewed electric scarifiers a few years ago. Since testing the Cobra S3840V Cordless Battery Scarifier & Aerator I am convinced cordless models will play a part. It’s not without it’s faults but still, if you need cordless, and you don’t want petrol – it is well worth a look!

Pros Scarifiers and aerators have similar functions but are not the same. A lawn aerator is a gardening instrument used to make holes in the ground to encourage lawn grass growth, whereas a scarifier is a tool with spikes that helps loosen and remove debris from the lawn surface, keeping the lawn looking green and tidy.

When it comes to choosing whether you go for an electric, cordless or petrol aerator, consider the pros and cons that are associated with each type: Petrol/Diesel Scarifiers: Ideal for larger lawns, these scarifiers are powered by petrol or diesel engines, offering increased mobility and power. They are suitable for heavy-duty scarifying tasks and are commonly used by professional landscapers. Spike shoes - these are cheap and easy to use and most effective on soft – but not soggy - ground in small gardens.Using a scarifier improves the overall health and appearance of your lawn.
