Types of Lawn Edgers and Trenchers

There are three main types of lawn edgers and trenchers: manual, gas, and electric ones. Here are some of their advantages and reasons to pick one over the other. 

Manual Edgers

As it’s clear from the name, this type of edgers and trenchers don’t need gas or electricity. You’ll have to put your hands and feet to work to edge your turf. They are still a common pick for smaller landscapes as they are convenient, don’t take much space, and are very compact and portable. Manual edgers require very little maintenance since there are no motors, bearings, or electricity involved, but best of all, it makes no noise! All you need to do is clean it up after use and store it away. Finally, manual trenchers and edgers are quite cheap and budget-friendly.

 One of the most popular manual trenchers is a roller edger that requires you to step and push the tool with your foot to cut the edges of your grass. Then there’s also a half-moon edger that looks like a spade or a shovel. You use it by pushing it into the ground and rocking back and forth to cut the grass.

Gas Powered Edgers

Gas-powered edgers and trenchers are the most powerful type of lawn edgers. Their power rating usually ranges from 20 to up to 160 cubic meters depending on the size. These larger lawn edgers are perfect for bigger yards and provide very consistent and clean cuts due to their sheer power. All gas-powered trenchers and edgers are on wheels, so you barely need any manual power. However, they are pretty noisy and cost a bit more than manual or electric edgers.

Electricity Powered Edgers

Electric-powered edgers can be corded or battery-powered and are very lightweight. Similar to handheld electric saws, battery-powered edgers have more portability over corded ones but need to be charged quite often. People prefer electric edgers over gas-powered ones since they produce no exhaust, aren’t as loud, and don’t require much storage space.

What to Consider When Buying a Lawn Edger and Trencher

Lawn size and shape

It’s pretty important to think about how big your lawn edging task will be. If you have a huge yard, using a manual edger will take a lot of your time and, most importantly, a lot of physical power, so it’s wiser to use a gas-powered edger for quick and effortless edging unless you’re really keen on a good workout!

Additionally, suppose your lawn has many tight edges or awkward-shaped flower beds close to the wall, bushes, or on a tight slope. In that case, the gas edger might be too bulky, so an electric or manual one will be easier to maneuver and work around tight spaces.


The more power your edger has, the easier it is to achieve a clean, sharp, and consistent edge on your lawn without much physical effort. A powerful gas edger is best for a clean and effortless cut if you have a long lawn with straight edges. Electric edgers aren’t as powerful but are much more maneuverable and lightweight. 

Blade type

Rectangular blade with a straight edge

This is the most simple and basic type of blade found on an edger. They are more than enough for small and straightforward lawn edging. Best suited for lawns connecting with same height driveways, walkways, or short flower beds. Rectangular blades should be used on gas and electric edgers only because you won’t be able to turn the rectangle shape blade with a manual edger.

Rectangular blade with scoop-cut ends

A rectangular blade with scoop-cut ends works best for garden, flower, and tree bed edging that has soil covered in mulch or other material. The unique shape of the blade allows for a delicate and precise cut without throwing weeds all over your flower bed.

Star-shaped blades

This type of blade can be used on gas, electric, and manual edgers. A star-shaped blade has many sharp points and can handle bushes, shrubs, small tree branches, and other dead greenery much more efficiently than rectangular blades. 

 If you’re using a manual edger with a star-shaped blade, it can also be used as a lawn aerator. Just make sure not to put too much pressure, and the blade will provide small punctures into the soil.

Safety features

When buying a non-manual lawn edger, make sure to consider safety features like trigger lock, debris guard, and padded grips.

Debris guards 

As the name suggests, a debris guard prevents debris from flying out the back of the edger into your feet and torso. Hard dirt and rocks can hurt you, while grass debris can stain your clothes.

Trigger lock

A trigger lock is the most common safety feature on any powered landscape equipment. It prevents users from accidentally starting the edger when picking it up or storing it. In order to start, the edger trigger lock needs to be pressed, held, and only then can you fire up the edger.

Padded grips and straps

Powered edgers and trenchers produce vibration, so having padded grips and over-the-shoulder straps allows for a much more ergonomic edger handling. Even if you’re working around short lawn edges or garden beds, padded grips make a huge difference.

Additional features or accessories

Adjustable blade position and angle

To deal with different types and shapes of flower beds and lawns, you might want to be able to adjust blade position and angle. Your lawn near a driveway might be close to the ground, while the garden bed will be deeper into the ground requiring different height edging.

Additional wheel

The additional wheel feature is helpful for heavier and bulkier gas-powered edgers. It can provide a lot of extra stability when on uneven surfaces and paved driveways or walkways. 

Cord length and battery size

When picking an electric lawn edger, make sure to check the length of the cord and battery size. If you have a large backyard, make sure the cord is long enough for your needs; otherwise, you’ll have to buy an extension cord. Cordless lawn edgers are not as powerful as corded ones and are best for smaller edging tasks. If you have a larger landscape and still want a lightweight and portable cordless edger, make sure to get on with a larger battery or one that has two batteries included to avoid having to recharge the battery in the middle of your chores.
