Hedges and bushes are assets to any home’s landscaping, providing much-needed privacy around patios and along property lines—until they get overgrown and require trimming, which can be a laborious chore. While tackling this job with manual hedge clippers is one solution, a gas hedge trimmer can get the job done much faster.

These landscaping tools use a gas engine to power a (usually) double-edged set of blades up to 24 inches long to quickly tame shaggy boxwoods and bushes. The best models have features that make them easier to use, such as dampening systems that take the edge off of engine vibration, rotating handles and wraparound bars that make them easier to maneuver, and quick-start systems that save the operator’s back from multiple pulls.

This guide will examine which features and characteristics are essential to consider when shopping for the best gas hedge trimmer and review some of the best models on the market.

What to Consider When Choosing the Best Gas Hedge Trimmer

While engine speed and power go a long way toward determining how well a hedge trimmer performs, other factors are just as crucial, including blade length, teeth spacing, and weight. Ahead, learn more about these and other important hedge trimmer characteristics.

Blade Length and Teeth Spacing

Trimmers have teeth on both sides, allowing the user to cut by waving the trimmer back and forth instead of having to use single strokes.

Trimmer blades range in length from 18 inches to 20 inches. A longer trimmer blade allows the user to cut more plant material with each pass of the trimmer. It also allows for more even cuts, which is crucial when trimming boxwood hedges to a precise shape. The added length, however, makes longer trimmers more challenging to handle than shorter trimmers. They’re also harder to maneuver in tight spaces, such as around the base of a bush or shrub. For most gardeners, an 18-inch trimmer should suffice, although those with large hedges should go with a longer model.

The blade has many teeth that scissor back and forth across one another like mini guillotines, cutting branches that fall into the gap between these scissoring teeth. The size of the gap between the blade’s teeth determines the size of the branches the trimmer can handle. Large, pro-grade trimmers typically have a gap of an inch or greater, allowing them to cut thicker branches and chew through denser material. Smaller trimmers for gardeners usually fall in the ⅜-inch to ¾-inch range.

Engine Speed and Power 

Compared to their electric-powered brethren, gas models are the more powerful hedge trimmers, capable of taking on bigger jobs and cutting through vegetation faster than electric models.

The power of a gas trimmer comes from the speed of its engine, which is measured in cubic centimeters of air and fuel displaced by the engine. The higher the number of cubic centimeters (ccs), the more powerful the engine. Most gas-powered trimmer engines range between 21cc and 25cc. Higher-power engines can better power longer blades, cut through vegetation more quickly, and trim larger-diameter branches.

Engine speed isn’t the only thing that determines a trimmer’s cutting ability. Trimmers with longer blades require more power to operate the blades. As such, a 23cc engine running a 23-inch trimmer may not be able to cut through vegetation as quickly as a smaller 21.7cc engine that’s powering a shorter 18-inch blade.

Fuel Capacity

Fuel capacity determines how long the trimmer can run before requiring a refill. Capacity is significant when undertaking bigger yard maintenance efforts in which delays for refueling may slow down the job. Most trimmers have a tank capacity of around 13 ounces, which equates to about 1 hour of run time. Keep in mind that larger engines will gulp down gas more quickly than smaller ones.

Weight and Ease of Use

Weight has a significant impact on the trimmer’s usability. A heavy trimmer can be challenging to lift and maneuver, whereas a lightweight trimmer will be more comfortable to handle and won’t fatigue the operator as quickly. Most gas trimmers range in weight between 10 and 14 pounds.

In addition to weight, other factors also affect how easy a trimmer is to use. Similar to gas lawn mowers, leaf blowers, and chainsaws, gas trimmers have pull starts. Many manufacturers have designed systems that make the motor easier to start when it’s cold.

Gas trimmer engines also create a significant amount of vibration, which can cause arm and hand fatigue. Some hedge trimmers have systems designed to dampen vibration that make the trimmer more comfortable to operate.

The handles on a trimmer can also make a big difference. Trimmers have a handle at the rear of the device that includes a trigger and handle closer to the blade. Many trimmers have wraparound handles near the blades that make the trimmer more comfortable to maneuver by allowing the user to take various hand positions to suit different angles of cut. Some trimmers feature trigger handles that rotate, making it even easier to cut at different angles.

Safety Features

Hedge trimmers have many sharp teeth for cutting through branches, making them inherently dangerous. As such, many come with safety features designed to minimize the risk of injury. Most trimmers require the user to hold down a trigger built into the handle to engage the blade. The blade automatically shuts off if the trimmer slips out of the user’s hands, which helps prevent accidents.

Most trimmers also have large guards between the blade and the handle to keep hands from slipping toward the blade while also preventing vegetation from interfering with the user’s grip on the trimmer while cutting.

This gas trimmer may not come from one of the more well-known names in landscaping tools, but it makes up for that with raw power thanks to an impressive 25cc engine, which is bigger than many trimmers at a higher price point.

With its lower price point, one might think this gas-powered trimmer doesn’t put out the same amount of power as other gas trimmers. Not so. Poulan Pro’s gas hedge trimmer boasts a powerful 23cc engine and a 22-inch-long cutting blade with wide-set teeth capable of chomping through 1-inch-diameter branches. This model also is easy to maneuver around bushes and trees, thanks to an innovative handle design that allows the handle to rotate 90 degrees to either side.

A long blade, easy-to-start engine, featherlight weight, and ability to cut larger branches make this the trimmer of choice for pros. At 23.7 inches, the 122HD60 has one of the longer cutting edges on the market, allowing it to tackle bigger jobs with relative ease compared to trimmers with shorter blades. Wide gaps between the teeth enable the trimmer to cut through branches greater than an inch wide.

Full days of landscaping work call for constant starting and stopping of the engine for breaks and refueling. With Husqvarna’s Smart Start engine, which purges air from the carburetor to make starting easier, breaks don’t have to mean multiple back-straining pulls to get up and running again. An anti-vibration system that reduces stress on arms and hands also helps to ease fatigue for long days of yard work, and an adjustable rear handle rotates to facilitate easier cutting from different angles.

Best Lightweight

With a design that extends the blade well beyond the length of a conventional hedge trimmer, this model from Echo is well suited for trimming large bushes and hedges. The 21-inch-long blade attaches to the end of a 22-inch-long shaft, providing plenty of reach for pruning more extensive shrubbery. With the blade extending farther from the user than traditional hedge trimmers, this model also has a safer design.

The user operates the trimmer via a molded handle with a trigger and a large wraparound handle farther up the shaft. The gear case that runs the blades is positioned between the user’s hand and the motor for a larger buffer between hand and blade. A vibration-reduction system and Echo’s easy starter make this trimmer easier to use, while a double-edge blade speeds up trimming jobs.

FAQs About Gas Hedge Trimmers

If you’re wondering about how to use a gas hedge trimmer, read on for answers to some of the most commonly asked questions about these powerful landscaping tools.

Q. Are gas hedge trimmers more powerful than electric or battery-powered ones?

Most gas-powered engines are more powerful than electric motors. For hedge trimmers, this means a gas-powered trimmer can cut through larger branches and denser vegetation more quickly than electric models.

Q. What kind of oil do I need to use with a gas hedge trimmer?

Gas hedge trimmers, like gas chainsaws and line trimmers, take two-stroke (also referred to as two-cycle) engine oil. Gas hedge trimmer fuel typically consists of 3.2 ounces of two-stroke oil mixed with a gallon of gas. Check the owner’s manual for the correct fuel ratio.

Q. How long can a gas trimmer run on a full tank?

A gas trimmer can run for about an hour on a full tank of gas, depending on use. Remember that hedge trimmers with larger engines will burn through gas more quickly than those with smaller engines.

Q. How do I start a gas hedge trimmer?

To start a gas trimmer, begin by priming the bulb on the gas tank. This will pump gas into the carburetor to allow it to start more quickly. Find the choke lever and set it to “choke.” The choke limits the amount of air intake into the engine, which allows a cold engine to start more easily. Holding the hedge trimmer on the ground, pull the start cord until the engine starts. Then move the choke lever to “run.”

Q. How do I store a gas hedge trimmer?

Store the hedge trimmer in a clean, dry place that is protected from rain and moisture. If the trimmer is in storage for the season, add a fuel stabilizer to the gas tank to prevent deposits from forming in the carburetor that can prevent it from starting in the spring.
