There are great benefits in scarifying your lawn in the long term but it can make it look a mess following treatment. it Is done because it makes the grass thicker, healthier and makes for a well-kept garden.

Scarifying is a process in which a tool is used to remove moss and thatch from the top of your grass. The idea is that the unwanted material on top of your garden makes the movement of nutrients and oxygen to your grass harder. Removing it allows the grass to breathe and grow and ultimately more grass seeds are planted giving a fuller, less weedy lawn.

There are variations of scarifiers on the market, you could opt for a simple garden rake or a manual scarifier with wheels if you want to do it by hand. Though many gardens are quite big and it can be a tough job by hand, so we recommend using an electric scarifier for small to medium gardens and a petrol scarifier for larger gardens.

Below we have compiled a list of our top 10 picks of every type of scarifier, allowing you to make an informed choice when you buy. Many contain an aerator feature, this is where it cuts the soil to make it less compact so it can breathe again for better growth.

Buyers Guide for Lawn Scarifiers

Oversized gardens with dense foliage can create an unruly mess. Not only does the yard look messy and untidy, but it also attracts pests, insects, and animals. Overgrown moss, lichen, and rot can cause severe health issues and can even cause accidents due to slipping or falling. To keep your lawn and garden manicured, you should invest in a few tools. One of these is a Lawn Scarifier. 

A lawn scarifier refers to a dethatcher, which is a useful tool to clean your gardens. This device is well-designed to cut through soil that helps in removing all dead moss plus other debris such as grass cuttings and other organic material.

How to Choose the Best Lawn Scarifier?

Though there are several varieties of lawn scarifiers available in the market, your choice depends mainly on the state or position of your lawn. 

Some useful tips to help you select the best lawn scarifier:

  •  Excellent quality of metal teeth blades 
  •  In-depth teeth of scarifier aerate a lawn by pricking holes in it. Opt for one that suits your soil type.
  •  Width of the cutting blade helps reduce the time spent using the lawn scarifier and helps save time and energy in the long term. 
  •  For small or medium-sized green, consider an electric scarifier.
  •  For large lawns, it is best to use petrol scarifiers.

Things to Consider When Buying a Lawn Scarifier


  • The most expensive part of the lawn scarifier machine is its motor. If you are going to buy a powerful engine on a cheap device, you should first check to ensure it will cover the entire expanse of your garden. In addition, you should also check if the motor is long-lasting. 
  • If your garden is extensive, then it is best to select a powerful motor which can make your task easy and quick. Along with doing a better job, a strong and powerful engine can withstand heavy loads for a longer time. 


  • You can easily find grass scarifiers and aerating tools along with an interchangeable head at a lower price point. Budget machines are the ones that attract the attention of buyers. Buy such budget models only if you have to use them over a small garden. Aerating drums of lawn scarifiers have blades which can make slits in the surface of the soil. Don’t set the machine for too low since it may cause undue stress on the functioning, and may have operational issues in the long term. 
  • Lawn scarifying machines are commonly angled on its springs that are attached to rotating drums. The accessories and tools of the machine are designed to loosen soft dead moss. For this reason, you should avoid stones, sticks, and fallen bark. All machines come with a collection box. Depending on the size of the machine, you may get a small collection box or a large one.

Height adjustment facility: There are many electric lawn scarifiers with height adjustment facilities to help all ages. Height adjustment also helps the machine go deeper into the grass and pull out dead moss. It is a useful quality which you should check before buying a lawn scarifier. However, it is better to start the machine on its highest setting, and then gradually decrease to a lower setting as it starts pulling bits of the thatch out and scarifying the grass. Most lawn scarifiers come with three levels and are usually sufficient for cleaning out medium to extensive gardens.   

Blades: The best lawn scarifier that you can buy is one with sharp knife blades. These knife blades help in the precise removal of all dead moss and thatch. For this reason, electric grass scarifiers are in high demand as they can rotate down into the grass with all its vertical blades and give a clean and precise cut without any loss of healthy grass.   

Brands: There are several known brands, like Bosch, Black and Decker, which are well-known in the field of garden care. They have some excellent variants of lawn scarifiers that you can avail. The Flymo Lawn Raker is another excellent machine and is also compact in terms of storage, plus it works better by removing dead thatch efficiently. The capacity box found in Bosch lawn scarifier can collect a whopping 50 litres, which is more than several others in the market.  Most of these brands also offer a warranty with their machines. They also offer replacement of faulty parts for a set time.
