Using a gas lawn edger can get messy and sweaty. Make sure you stay hydrated and wear clothes you don’t mind getting dirty.

Key considerations

Advantages of gas

Gas is often the preferred power source for large, intense edging tasks. Gas tools offer more potency than electric tools, and they definitely exert more power than manual tools. A gas lawn edger easily digs deep into soil, especially in areas that haven’t previously been dug up. They are similar in size to, or even larger than, electric edgers. It’s pretty easy to find a gas edger sized for the project you want to tackle.

Gas lawn edgers are also known for precision. While electric and manual edgers tend to be handheld, gas lawn edgers are wheeled machines that create uniform depth throughout the job.

If you own other gas-powered items, such as a gas lawn mower or gas hedge trimmer, incorporating a gas edger into your collection should be fairly simple, as they require similar maintenance and safety precautions.

Drawbacks of gas

Gas-powered lawn edgers are heavier and pricier than their electric counterparts. Gas lawn tools in general, and lawn edgers in particular, can contribute to noise and air pollution. Some require the use of earplugs. As they can be large and bulky, you will need a suitable place to store the machinery. Also, bear in mind that you’ll need to regularly gas up the machine. 


Gas-powered lawn edgers, which feature one or more wheels, are appropriate for medium to large lawns that require regular maintenance. They’re useful if you have gardens, flower beds, pathways, trees, and other areas you want to define. To achieve a precise cut, wheel the gas edger slowly forward. The pace should be much slower than you’d move a lawn mower.


Gas-powered lawn edgers come with two-cycle or four-cycle motors. If you use a two-cycle machine, you must mix the oil and gas in proper proportions. If you use a four-cycle machine, the gas and oil mix automatically. The latter are more powerful and energy efficient. They also tend to be larger, louder, and pricier.

Engine power

Engine power for a gas lawn edger is measured in cubic centimeters (cc) or torque. These machines range from 20 cc all the way up to 150 cc, or from 5 to 7 foot-pounds of torque. The higher the numbers, the more powerful the machine. Higher numbers also indicate a higher weight and price.

Blade depth

Consider the size of the blade and how deep it can cut into the earth. You may want several depth options to cater to different areas of your lawn. For edging around driveways and sidewalks, a 2-inch depth would probably suffice. You may want a more pronounced boundary in other areas. Note that if you’re burying cables in your lawn, you’ll need much greater depth.


Gas lawn edgers are heavy, with some weighing 60 to 70 pounds. While the wheels tend to be durable and the units relatively easy to push, consider the slope and terrain of your yard before buying. It’s more difficult to push a heavy edger up a slope.


Adjustable blade angle

An edger with an adjustable blade angle can create more intricate cuts. Some blades tilt slightly to create a beveled edge. The degree to which the blade can slant varies from model to model. Some turn up to 90 degrees and perform trimmer functions as well.

Wheel height

While changing the height of the blade helps with depth, you may want to go over or around certain obstacles on your lawn. Some edgers allow you to adjust wheel height for further customization. This is particularly useful if you’re edging a curb.

Gas lawn edger prices

Inexpensive: The bigger and more powerful the edger, the pricier it will be. At a minimum, you can expect to pay around $150 for a gas-powered lawn edger.

Mid-range: Gas lawn edgers that are more potent can cost up to $300. These tend to be four-cycle machines with adjustable features.

Expensive: The most durable and powerful gas lawn edgers cost around $500. These machines are useful for contractors and others who use them regularly.


  • Start by mowing. A lawn mower is a great tool to lead off your landscaping project. Make your edging and trimming jobs easier by cutting the grass and weeds first.
  • Wear protective gear. Pebbles, rocks, and twigs can inadvertently fly around when you use an edger. Keep your hands, wrists, feet, ankles, ears, and eyes protected when edging.
  • Survey the area. Before using an edger, check the area for objects that may cause problems. Remove rocks, branches, and stray toys that may have been left out.
  • Engage your core. Pushing a gas lawn edger can be tiresome. Use your core to endure most of the workload so your arms don’t wear out. Avoid slouching, as this could hurt your back.

Opt for deeper cuts around gardens and flower beds to give them a prominent look and some protection. Consider placing shallower edges around sidewalks and driveways.


Q. How should I maintain my gas lawn edger?
Regularly remove soil and grass from the edger after use. (To do this, wear a pair of work gloves, and make sure the machine is properly turned off first.) Removing the debris prevents it from hardening around the blade.

Your blade may need to be regularly sharpened, depending on how often you use the edger. The average user can expect to sharpen the blade several times a year. This can be done at home or in a shop.

Q. How should I store my gas lawn edger in the off-season?
Before storing your gas lawn edger for a long period of time, make sure the tank is empty of gas. You may want to incorporate a fuel stabilizer so the machine doesn’t clog with leftover gas. Siphon out the gas, or run the machine until it shuts down. You’ll want to drain the oil as well. Some people invest in a cover for their tool to provide additional protection.

Removing the blade prior to storage can help keep it sharp and durable. Store the edger in a cool, dry place free of exposure to humidity, heat, and moisture, which could lead to rust or corrosion.

Q. When is the best time to edge my lawn?
For the best results and lightest workload, edge your lawn when the ground is slightly damp. If it’s too hard, the process will be much more difficult. If it’s too wet, the soil will yield messy, uneven results. Try edging early in the day or late in the evening to avoid the hot midday sun.

Q. What’s the difference between an edger, a trencher, and a trimmer?
Depending on the type of edger you purchase, it may be able to do the job of a trencher or trimmer, both of which perform similar tasks to those of an edger.

A trencher is essentially an edger than can dig deeper and wider, usually with greater efficiency. Often, a large-bladed edger will be referred to as a trencher.

An edger that uses a string (common on electric options) to operate can function as a trimmer, too. While edgers create vertical boundaries, trimmers create horizontal edges. String trimmers are also known as weed eaters or weed wackers.
