Things to Consider when Buying the Best Lawn Dethatcher

So you may be wondering the type of lawn dethatcher to buy to get rid of the stubborn thatch in your lawn. After going through some of the best models, I understand if it gets a little hard to choose.

That's why I am here to guide you. When you want a good lawn dethatcher, you will not just go online and order or store and pick a specific model. You will first need to know how that product works and if it is suitable for the work you want to be done. Therefore, if you plan to buy a lawn dethatcher and somewhat feel confused about the model to buy, here are key features to look for in good lawn dethatchers.

a). Lawn Size

Your lawn size is one of the major things you should keep in mind when buying a lawn dethatcher. Some dethatcher models work greatly when the yard is small, but they may be wanting when subjected to a lot of work.

Therefore, keep in mind this important factor before you order that dethatcher. Ensure that you get the right model for your yard size.

For small lawns, a manual dethatcher can work perfectly. On the other hand, a larger yard will need a motorized dethatcher or a tow-behind dethatcher that attaches to a tractor.

b). Motor Power

Lawn dethatcher motors range from 10-15 amps, with 15 being the most powerful. Dethatching a large lawn will require a dethatcher with a more powerful motor; this is just to ensure that you don't take breaks to give the engine time to cool.

A larger motor will cool the engine as it works. However, a smaller yard will need a dethatcher with a small motor as the dethatcher's engine cannot overheat from little work.

c). Tines

When it comes to dethatching, it is the tines that do all the work. They reach into the lawn and remove all the thatch that is hidden beneath the grass. Without good tines, it is not possible to remove thatch.

Therefore, you need to ensure that you buy a lawn dethatcher with very powerful and durable tines. Stainless steel tines and spring tines are the best as they do not rust (this means they will last longer) and are also strong, meaning they will handle the resistance from the thatch during dethatching.

d). Dethatcher Width

Dethatchers come in different sizes, with the width ranging between 12 to 48 inches or more. This makes it easier to get smaller products for smaller yards and vice versa.

If your dethatcher is big, you will only make few passes before you finish removing thatch. However, if you use a dethatcher with a small width to work on a large yard, you may spend more time than you wanted.

However, it can be very difficult to manoeuvre a wide dethatcher in a narrow dethatching path. Keep this into consideration before you make that purchase.

e). Collection Bag

If your lawn dethatcher is bagless, you are likely to spend the better part of your day raking and removing the thatch from your lawn after dethatching. Therefore, before you decide to buy a bagless dethatcher, you need to know the available options.

However, even if you buy a bagless dethatcher with a mower with a bag, you can still get your work done faster because the mower will provide the service needed. Most dethatchers, however, come with collection bags.
