Hedges establish boundaries in landscaping, add privacy, and benefit curb appeal. But in order to look their best, hedges must be groomed. Power hedge trimmers are designed for this very purpose. The best hedge trimmers make it much easier to shape and otherwise control growth and vegetation in the yard.

Read on to learn the key considerations to keep in mind when choosing one of these handy outdoor tools—and don’t miss our roundup of top-favorite picks among the best power hedge trimmer options available today.

Before deciding on the best power hedge trimmer for a yard, it’s important to consider the power source, engine, blade sizes, and whether it’s better to use an electric hedge trimmer or if a gas model is a more appropriate option. Read on to find out more about these factors in order to find the best hedge trimmers for maintaining the yard and creating a well-groomed privacy border.

When searching for the best power hedge trimmer, there are two power options: gas and electric. The decision is usually based on how much power and portability are needed.

Engine power is the force produced by the engine to drive the hedge trimmer blades, allowing them to cut through leaves, twigs, and small branches. The way that engine power is measured depends on the type of power hedge trimmer.

Blades can be single- or double-sided, and they come in a wide range of sizes from 13 inches to 40 inches in length. Choosing the right blade size is an important step that can make hedge-trimming jobs much easier.

Left-handed individuals may find it easier to use a power hedge trimmer with a double-sided blade because the majority of single-sided blades are made for right-handed people.

The fuel capacity refers to the amount of fuel that a gas power hedge trimmer can hold in the fuel tank. The capacity is typically used to determine how long the trimmer can operate on a single tank of gas. This is an important feature that can help determine the suitability of a gas-powered hedge trimmer. Naturally, larger yards will benefit from a trimmer with a higher fuel capacity so that they can operate long enough to complete the required yard maintenance.

The average gas-powered hedge trimmer has a tank capacity that ranges from 10 to 16 ounces. This fuel tank will usually require a mixture of gas and oil at a ratio of about 40:1 or 50:1, though users should always refer to the manufacturer’s directions for the proper fuel ratio. Trimmers operate for between 45 minutes and 2 hours, depending on the weight of the machine, the size of the engine, and the material that’s being cut.

Another factor to consider is the thickness of a branch that the trimmer can tackle. Most slice through branches up to ½ inch thick, while more powerful models can usually handle up to an inch in diameter. Check the size of the gap between the blade’s teeth. This is referred to as a blade gap, and the greater the gap, the higher the cutting capacity.

A majority of residential trimmers have a gap of between ⅜ and ¾ of an inch that’s suitable for leaves, twigs, and small branches. However, professional or commercial-grade trimmers can have a blade gap wider than 1 inch, allowing them to take on small trees and oversize hedges.

Batteries are one of the three main fuel sources for power hedge trimmers, with most models using a long-lasting lithium-ion battery that can range from 20 to 80 volts. The battery life of a hedge trimmer can differ depending on the weight of the trimmer, the age of the battery, and the amount of material the trimmer is cutting.

On average, a hedge trimmer battery can last for between 30 minutes and 1 hour and will take between 30 minutes and 2 hours to fully charge. Keep in mind that some hedge trimmers don’t come with a battery or a battery charger, so users may need to purchase the battery separately. If this is the case, it’s a good idea to get two batteries so that one is always charging while the other is in use.

Hedge trimmers can range in weight from battery-powered options that weigh only 5 pounds to heavy gas trimmers weighing more than 20 pounds. A tool that is well balanced in weight from the front to the back usually offers better support and reduced muscle fatigue.

There are a few features that make it easier to hold and control hedge trimmers. A padded front handle enhances comfort and gives users a better grip on the trimmer. Telescoping poles are another useful feature, allowing the trimmer to cut branches and leaves. This extendability means users don’t have to stretch or climb up and down a ladder repeatedly, effectively reducing muscle strain.

When choosing a power hedge trimmer, safety should be the highest priority so that you can trim the vegetation in the yard without having to worry about a hospital trip. With that in mind, manufacturers have built-in several safety features to help make power hedge trimmers a safer option for managing the garden, including blade brakes, safety switches, padded front handles, and front handle shields.

This list narrows the field to some of the best hedge trimmers on the market. It includes impressive engines and laser-cut blades with wide-set teeth that can handle cutting and shaping thick vegetation.

Despite the power of this trimmer, it weighs only 9 pounds and features a cushioned grip to help reduce muscle fatigue and strain caused by vibration.

The power hedge trimmer is made with an electric brake stop to immediately cease the momentum of the blade as soon as the trigger is released.

This compact energy-efficient trimmer weighs little more than a laptop—about 5.5 pounds, allowing users to control the trimmer with ease. What it lacks in size it makes up for in power.

The dual-action steel blades, protected by a rustproof aluminum cover, can slice through twigs and branches up to ¾ inch in diameter. This model also comes with a 20-volt battery, battery charger, and a blade sheath to keep the blade protected when the trimmer is not being used.

This heavy-duty gas hedge trimmer has a wide 1-inch cutting capacity that’s suitable for maintaining well-established hedges, bushes, and small trees. It weighs 11.1 pounds, which is heavier than the standard electric- or battery-powered trimmer, but it’s on the light side for a gas trimmer. The extra weight is due to the powerful 23 cc engine that drives the 22-inch dual-action blade for up to 1 hour on a full, 13-ounce tank of gas.

The power hedge trimmer requires a 40:1 gas-to-oil mixture, and the safety switch needs to be held down for the trimmer to start. For better maneuverability and control, this trimmer has a rotating handle with a cushioned grip to help reduce vibration during operation.

Adding a power hedge trimmer to your yard maintenance arsenal can help keep vegetation under control. However, you may still have questions, like whether a gas or electric cordless hedge trimmer is more powerful or what type of oil is best. Take a look below for the answers to these and several more frequently asked questions about hedge trimmers.

Hedge trimmers are lightweight tools made for trimming smaller branches, leaves, and vegetation. Hedge cutters are a more robust tool that cuts through much thicker branches and even the trunks of very small trees, shrubs, and hedges.

Battery-powered hedge trimmers have a limited amount of power because they must convert energy from the lithium-ion battery to the electric motor. Corded electric hedge trimmers are more powerful because they have a direct connection to a power source. However, the most powerful type of hedge trimmer is gas due to the large combustion engine that burns gas at a controlled rate to drive the blades.

It’s advised to use the oil that is recommended by the manufacturer. Typically this will be a 2-cycle blend like the Briggs & Stratton 2-Cycle Easy Mix Motor Oil that is a fuel stabilizer or the semi-synthetic Husqvarna HP SYNTH 2-CYCLE OIL.

The EGO Power+ 24-Inch 56-Volt Cordless Hedge Trimmer is one of the best cordless hedge trimmers on the market due to the 24-inch dual-action hardened-steel blades and 1-inch-cut capacity.
