If you are looking for something that offers deep cutting alongside precision and power, then the Worx edger would meet your needs.

What is an Edger?

A yard edger tool is a common piece of garden equipment that is used to create a boundary along the edges of the lawn. This boundary will prevent the grass from growing over into other parts of the garden and will leave you with a professional and well-manicured lawn.

These tools come in a variety of different types, and this is surrounding how they are powered. In the main, you will use one of four different grass edger trimmer; electric, battery-powered, gas or manual.

Each type of lawn edger trimmer is designed to create a precise and straight edge, and the style you use will depend on several factors including the size of your lawn, your access to power and your personal preference.

What is Trenching?

Trenching refers to creating much deeper and larger borders and is commonly used when making things like flower beds or a deeper border around large structures such as a tree.

To create trenches, you will need a much larger and more robust tool, although trenching can be achieved with a manual grass edger, this would be far more physically demanding.

Trenching comes with a whole world of benefits; many are similar to edging the lawn and include preventing the grass from growing into other areas such as where flowers are planted. However, you can vastly alter the aesthetic of your garden by trenching, and this will make your garden much more appealing.

Can a Lawn Edger be Used as a Trencher?

The good news is that if you already own a lawn edger tool, you can use the edger as a trencher. However, it is essential to keep in mind that a gas or electric model will be far more powerful and a lot easier to use when digging these deeper and longer holes in the ground.

Many garden edger tools will come with an adjustable depth setting which means that you can dig anywhere from half an inch to a few inches, this makes an edger for lawn care an excellent option for trenching.

If you are going to use a trencher for edging, you must remember to alter the depth accordingly so that you can create a trench that is the right size.

Things to Consider

If you want to kill two birds with one stone then finding a lawn trencher and edger in one is a surefire way to do this. However, you will find that there are many substandard tools on the market and also those which may be useful for merely edging but where trenching is concerned, may be lacking.

With this in mind, it is crucial to take your time to explore your options and find a garden edger tool that will work well for you and meet your needs. Looking at the various features of each lawn edger can help you to determine if the machine is the right fit.

Power Source

As we have discussed, lawn edger trimmers come in a variety of forms, and the way in which they are powered will have an impact on how they perform. If you are looking for a tool that will double as a trencher, then you will want to find something that has a decent level of power and can offer excellent performance.

Manual lawn edgers are great for small gardens and for creating a small boundary around the edge of your lawn. However, when it comes to the more demanding task of trenching, you will likely find that using a manual tool is far too strenuous and takes far too long. In contrast, powered tools like the gas and electric powered yard edger tool will deliver continuous power and have blades that rotate at some impressive speeds. This means that what may have been a lengthy and challenging task is made far easier. Gas edgers are known to have the most incredible amount of power, but some of the modern electric models are beginning to rival this.

There are also battery powered lawn trenchers, but since you are limited on how long you can use them before the batteries need to be recharged, they may not be the best edger trencher for this type of work.



We mentioned that the speed at which the blades move has a bearing on the power and ability of the grass edger trimmer. The RPM will tell you how many times in a minute the blades spin and what is most impressive is that there are some incredibly speedy edger tools out there that will make cutting through even the most solid ground look like a hot knife through butter.


Lawn Size

One of the most important things to think about is the size of the area you will be working in. This will also help you to determine the type of lawn edger that will work well for you. If you are working on a very large project, a battery-powered option would not be suitable, for example.

You will also need to consider the things that might be an obstruction. Some people use a trencher for pruning tree roots, and in this case, you would need an extremely robust piece of equipment with strong blades.


Ease of Use

It stands to reason that you are not going to want a trencher that is going to be complicated to use. Since trenching can sometimes be a big job, the last thing you need is a complex tool. There are several things that might make your trencher for edging a lot more user-friendly, and this could include how easy it is to adjust, where the power controls are located and whether the handle is adjustable for comfort.

You should also consider the weight of the product since some edgers, particularly those that are gas-powered, can be very high, and this can make them difficult to move around.


There has long been confusion among homeowners as to the difference between edging and trenching. Both of these garden maintenance jobs involve creating boundaries and digging into the ground; however, trenching digs far deeper and is often used for things like flower beds.

If you need to be able to do both of these jobs, you probably won’t be looking to fork out for various pieces of equipment, especially when you learn that a lawn edger can often be used as a trencher.

There are several lawn edgers that also work as a landscape trencher, but before you go running off to the store, you may wish to take a few things into consideration to make sure that you are getting a tool that is up for the job.

We have sourced three of the best edgers for trenching that are powerful, easy to use and affordable; we are confident that you will be just as impressed by them as we were.
