Electric hedge trimmers are a great way to keep your hedges and shrubs in shape. They are designed to make trimming and shaping your plants faster, easier and more precise than manual tools like shears or clippers. When choosing an electric hedge trimmer, it's important to consider the size and type of your hedges, the weight and length of the trimmer, and the power source. There are two main types of electric hedge trimmers: corded and cordless. Corded trimmers are typically more powerful and can handle larger jobs, but they require an electrical outlet and a long extension cord. Cordless trimmers are more portable and easier to manoeuvre, but may not be as powerful as corded models. Other factors to consider include the length and type of blade, with dual-action blades generally considered more efficient and effective.

What You'll Learn

Electric vs. petrol vs. corded
Electric, petrol, and corded hedge trimmers each have their own advantages and disadvantages. Here is a detailed comparison to help you choose the right one for your needs:
Electric hedge trimmers are a popular alternative to petrol trimmers and are ideal for a broad range of users. They have improved significantly over the years and are now powerful enough for most trimming jobs. Electric trimmers are available in both corded and cordless models. The corded models require access to a power outlet, which limits their range and mobility. They are, however, affordable, low maintenance, lightweight, and easy to operate. Electric trimmers are also environmentally friendly, as they do not emit fumes. They are generally much lighter than petrol trimmers, making them easier to handle and suitable for extended use.
Petrol hedge trimmers, on the other hand, offer greater mobility as they are cordless. They are powerful and can be used anywhere, making them ideal for large gardens or thick hedges. However, they have several drawbacks. Petrol trimmers are heavy, noisy, and require regular maintenance. They are also more expensive to operate and have an environmental impact due to fuel usage. Additionally, the process of mixing and pouring fuel, as well as the possibility of fuel leaks, can be messy and inconvenient.
Corded hedge trimmers are generally more affordable and lightweight than their cordless counterparts. They are low maintenance and can be ideal for small to medium-sized gardens with easy access to a power outlet. However, the presence of a power cord can be a potential hazard, and the length of the cord may limit your reach, requiring the use of an extension cord.
In summary, electric trimmers (both corded and cordless) are lightweight, quiet, and environmentally friendly. Petrol trimmers offer greater mobility and power but are heavier, noisier, and require more maintenance. Corded electric trimmers are budget-friendly and suitable for smaller gardens, while cordless options provide greater mobility but may be more expensive due to battery costs.

Hedge size and type
The size and type of your hedges are key factors in choosing the right electric hedge trimmer.
If you have large, thick hedges, you may need a more powerful trimmer with longer blades. Corded trimmers are typically more powerful and can handle larger jobs, but they require an electrical outlet and a long extension cord. They are also more limited by their mobility. If you opt for a cordless trimmer, you may need to purchase extra battery packs to provide extended runtime for larger jobs.
If you have smaller, more delicate hedges, a lighter, more manoeuvrable trimmer may be a better choice. Trimmers with shorter blades are easy to manoeuvre and make quick work of smaller hedges and bushes. If you need to trim hard-to-reach areas that are high up, a pole extension will give you the length you need to get the job done.
The type of blade is also important. Dual-action blades are generally considered more efficient and effective, reducing vibration compared to single-action blades. The distance between the teeth is another factor to consider. Narrow spacing (12-16mm) is ideal for finer cuts on young hedges or delicate topiary work, while wide spacing (20-36mm) is suitable for thicker branches and overgrown hedges.

Weight and price
When selecting an electric hedge trimmer, weight and price are important factors to consider.
Firstly, weight. You should check the weight of the trimmer to ensure you can safely control it and work with it comfortably. A heavy trimmer can be difficult to manoeuvre and may cause fatigue, so it's important to find one that has a balanced weight distribution and feels comfortable in your hands. Single-sided hedge trimmers, for example, offer longer blades without adding too much weight to the machine. If you opt for a cordless trimmer, bear in mind that the weight of the tool should be well-balanced between the front and the battery.
Now, price. The price of hedge trimmers varies considerably according to size, power, and power type, ranging from less than $200 for smaller models to several hundred dollars for larger, professional ones. Cordless trimmers used to be very expensive, but recent advances have lowered their price. However, keep in mind that the cost of batteries and chargers can increase the overall cost of ownership. If you don't need to trim your shrubs often, a smaller, less expensive option may be more suitable.

Blade length and type
The blade is one of the most important features to consider when selecting an electric hedge trimmer. The length and type of blade will impact the trimmer's cutting capacity, ease of use, and maneuverability.
Blade length is typically measured in inches or centimeters and can range from around 13 inches (33 cm) to over 24 inches (61 cm) on electric models. Longer blades are better suited for trimming larger areas and can cut through thicker branches, but they also add

Safety and maintenance
Safety Precautions:
- Always wear protective gear, including gardening gloves with good grips to prevent scratches, cuts, and vibrations, and safety glasses to shield your eyes from flying debris like twigs, leaves, and insects.
- Check your equipment before use to ensure it is in proper working condition and hasn't been damaged.
- Avoid trimming hedges during the rain or when rain is forecasted. Working with electricity in wet conditions can be hazardous.
- Dress appropriately, avoiding loose-fitting clothes that could snag on branches. Ensure your clothing allows for a free range of motion but fits tightly.
- Keep children and pets safely away from the work area to prevent any accidents or interference.
- Be mindful of nesting birds, especially during breeding season (March to August). It is illegal to intentionally harm an active nest.
Maintenance:
- Blade Cleaning and Sharpening: Clean the blades after each use with a damp cloth or brush to remove plant sap, debris, and dirt. For battery-operated trimmers, remove the battery before cleaning. Wipe the blades with a clean, dry cloth to prevent rusting and ensure clean cuts. Sharpen the blades regularly, following the manufacturer's guidelines, and consider consulting a professional for optimal safety and effectiveness.
- Cord Care (for corded models): Avoid tangles by wrapping the cord neatly and storing it in a shady place to prevent sun damage to the insulation.
- Safe Storage: Store the trimmer in a cool, dry place, out of the reach of children and animals.
- Lubrication: Lubricate the hedge trimmer blade with lightweight machine oil before and after each use for optimal performance and blade longevity.
- Battery Care: For cordless models, ensure batteries are fully charged per the manufacturer's instructions.
- Footing and Grip: When using a pole hedge trimmer, maintain proper footing and balance. Hold the unit firmly with both hands, keeping your left hand on the pole shaft and your right hand on the rear handle, ensuring your body is to the left of the blade line. Avoid cross-handed or left-handed grips that place your body or arm across the blade line.
By following these safety and maintenance guidelines, you can ensure the efficient and safe use of your electric hedge trimmer while also prolonging its lifespan.
