Must Know Facts before Buying Lawn Dethatcher

If you work with your lawn regularly, then you might have the proper tools for your lawn. Almost every year, Americans buy around 3.5 million lawn dethatcher machine. First of all, you have to understand the benefits of dethatching your lawn. This is very important because, if you have no idea about dethatching your lawn then you will not be able to pick the best one.

When dethatching, you must be aware of your lawn because this is very important for your lawn health. If you have no idea about dethatching, then compare it with combing. In combing, you have to comb out debris from your lawn. Yes, you can try it with your hands but isn’t it much easier to take help from a dethatcher? This machine makes your lawn perfect and beautiful.

The first thing to consider when buying a lawn dethatcher machine is a comfort. If you don’t own a dethatching machine, then you have to spend a considerable amount of time to dethatch your lawn. However, it is very important that you consider comfort before anything else. Examine hand positions, moving features, wheels, and anything that can enhance comfort.

The next point is the longevity and durability of your machine. You don’t want to buy a dethatcher machine every summer, right? Build quality is an important thing you should look for in a lawn dethatcher. Have a look at the main body and motor. A blade is another thing to consider, but I will suggest you don’t worry about this because you can easily change it anytime and blades are relatively cheap.

Choose The Perfect Dethatcher Machine

You might be interested in buying a model that is convenient for tidying up small lawns, or a more powerful mower machine that is capable of cleaning long grass in a large yard. Another consideration is your physique, specifically your height. There are some models on the market fitted with adjustable height handles, and that feature makes them more flexible and comfortable to use.

The last point that you should keep in mind is the environment you intend to use the mower/dethatcher machine. There are some models that are best for sloppy areas and easy to maneuver in areas with trees or a small pond. Look of your lawn that you want to see is also important. You may be happy with small grass or want a more decent striped look.

In terms of blade style, there are three types of lawn dethatching machine available on the market. One is cylinder machines fitted with a rotary blade at the front, specially designed for cutting grass in a scissor motion. If you have a lawn that needs to be cut more often then, this is the perfect pick for you. However, this is not recommended for those who have a lawn that has an uneven surface or dump and long grass.

Hover dethatchers are the most ideal for overhanging shrubs and unsuitable for small sized lawns. You can choose one that collects the thatch after the cutting process; it contains a bag for picking up afterwards. It is cheaper than the cylinder or rotary models. And lastly, rotary dethatchers are fitted with a blade underneath that allows you to finish the work within a few rounds.

Frequently Asked Questions

What is a dethatcher?

A lawn dethatcher or scarifier is a tool used to remove thatch from lawns. Thatch is a buildup of organic matter which includes dead grass, leaves, stems, grassroots, and lateral weed growth. Removing thatch helps the grass to thicken, making it stronger and less susceptible to disease. Also, reducing thatch allows more water, air, and nutrients to get through the roots of the grass. To put it simply, dethatching is good for grass health.

Dethatching is a process wherein metal blades, tines or prongs rigorously scrape the surface and subsurface of the lawn. A lawn dethatcher uses rotary blades to cut thatch and bring them to the soil surface. There are different types of dethatchers that you can use on your lawn.

What are the different types of dethatchers?

Dethatchers can be classified into three categories:

Manual Dethatchers

These affordable tools have a simple design and look similar to a garden rake. The only difference is that a dethatching rake has sharp, blade-like tines. Manual dethatchers work best on areas that are hard to access for other types of dethatchers. The disadvantage of using this tool is that it requires a lot of time and physical effort when you’re working in a large area.

Power Rake Dethatchers

This is a dethatching machine that is either an electric dethatcher or a gas powered dethatcher. It has adjustable bottom blades and has a similar design to a lawnmower. A power dethatcher usually has width and height adjustment settings so that you can use it on any thatch thickness or grass type. Some models also have a collection box that makes dethatching easy. A power rake dethatcher does an excellent job in vast areas.

As mentioned above, there are two types of power dethatcher. An electric dethatcher uses either wire or spring tines. It is ideal for thatch on huge lawns. It is designed for shallow dethatching. If you have a relatively small property and want to dethatch your lawn, you can consider buying this item.

On the other hand, a gas-powered dethatcher is a durable machine that is designed for heavy work. It is ideal for wide areas with thick lawns. To get the best dethatcher, pick one with sharp fixed blades (not rounded). For bumpy areas, use flail or swinging blades.

Tow behind Dethatchers

A tow behind dethatcher is designed to be attached to a riding lawn mower or tractor. This tool is efficient, as it can cover a large area within a shorter time compared to other types of dethatchers. Before dethatching, the blades should be height adjusted correctly and tightly hitched.

When is the best time for dethatching lawns?

The best time for dethatching a lawn depends on whether you have cool-season grasses or warm-season grasses. If you’ve got cool-season grasses, dethatch either in early spring or early fall. It is the best time for growth, helping them recover from the stress of the dethatching process. Meanwhile, if you have warm-season grasses, it’s best to dethatch your lawn in late spring.

Final Review of the Best Lawn Dethatcher
