Pros & Cons of Dewalt DCHT820B
What kind of vegetation will you be cutting?
The DEWALT DCHT820B is equipped with a 22-inch dual-action blade that can easily cut through most shrubs and hedges. It is suitable for light, medium, and thick vegetation. If you’re looking to tackle larger branches or limbs, you may want to opt for a more powerful model.
Choosing your power type
When it comes to powering your hedge trimmer, you can either opt for battery or corded. DEWALT DCHT820B offers both options so you can choose the one that suits your needs best.
The battery is compatible with all DEWALT 20V Max tools, which means you won’t have to buy a new one if you already own other products from their range. With its lightweight design and long run time, this will give you the freedom to work wherever and whenever you need without worrying about finding an electrical outlet nearby.
On the other hand, if you prefer a more powerful option then the corded version is a better choice. This one comes with an 8-amp motor that is designed for tougher tasks and can easily cut through branches up to 3/4 inch thick. The 6-foot power cord gives you plenty of room to move, so you won’t have to be tethered while trimming.
Corded hedge trimmers
Corded trimmers are the most common type of hedge trimmer. They have a long cord that you plug into an outlet, which gives them the power to cut through thicker branches and tougher shrubs. Corded models are typically powered by electric motors, making them easier to maneuver and control than gas-powered trimmers. They’re also usually lighter in weight, so they’re less of a strain to use for extended periods of time. The downside is that you’ll need to be close to an outlet while using it, but if you have large hedges or shrubbery these are probably your best bet. Just make sure you purchase one with enough power and length for your needs!
Cordless hedge trimmers
Cordless trimmers are the most convenient way to groom your hedges. They offer a great deal of freedom and flexibility when it comes to trimming and shaping your garden hedges, as they eliminate the need for a long cord that can easily be tangled or caught up in nearby plants or shrubs. Cordless hedge trimmers also tend to be lightweight, making them easy to maneuver around difficult areas or larger bushes and shrubs. Many models come with rechargeable batteries, giving you plenty of time to get all your pruning done without having to worry about running out of juice mid-way through the job. Most cordless models are also quiet and produce minimal vibrations – perfect for keeping disturbances at bay in more sensitive residential neighborhoods. So if you’re looking for a convenient and hassle-free way to keep your hedges in check, cordless hedge trimmers are the way to go!
Petrol hedge trimmers
Petrol trimmers are an essential tool for any garden maintenance job. They provide a clean, efficient way to trim and shape hedges, and can be used on bushes of any size or height. They have several advantages over electric models: they have more power, so they can cut through thicker branches; they’re more portable, as you don’t need access to an electrical outlet; and their fuel tank allows them to run for longer before needing a refill. Ensure to check out the range of models available, as well as their weight and balance. You should also consider safety features such as anti-vibration handles and blade guards. With the right model, you’ll be able to easily and safely maintain your garden hedges. 
Choosing the right trimmer for your hedge
Trimming your hedge can be a time-consuming job, but it’s an essential part of keeping your outdoors looking neat and orderly. But with so many different trimmers on the market, how do you choose the right one for you?
The most important thing to consider when choosing a hedge trimmer is the size of your hedge. If you have a small hedge, then a smaller trimmer with shorter blades will work fine. However, if you have larger hedges then it’s best to go for something with longer blades, as this will make trimming easier and quicker. You also want to think about how powerful the motor is – the more powerful the motor, the faster and more efficient it will be at cutting through thick branches.
Another important thing is the weight of the trimmer. If you’re going to be using it for long periods of time, then you want something lightweight so that you won’t get fatigued easily. You should also look at the type of blades used – some come with serrated edges which make cutting easier but will dull quicker than a standard blade, whereas others might have special features such as an anti-jamming system or a telescoping handle to help reach higher branches.
Finally, think about how easy the trimmer is to use and maintain – look for one with simple instructions and parts that are easy to replace if they break. Safety should also be considered here – choose one with a shield to protect you from flying debris, and if possible opt for one with an electric start or an automatic stop system.
By taking all these factors into account, you can rest assured that you’ll be able to find the perfect trimmer!

Hedge trimmer features
A hedge trimmer is one of the most important tools for any homeowner. Hedge trimming can be a tedious and time-consuming task, but with the help of hedge trimmers you can quickly keep your hedges looking neat and tidy. Here are some of the features to look out for when buying a hedge trimmer:
- Electric or gas-powered: Electric trimmers tend to be more convenient, as they don’t require fuel like gas-powered ones. They are usually lighter with less vibration than their gas counterparts, making them ideal for smaller tasks.
- Blade length: Most hedge trimmers come in blade lengths ranging from 6-14 inches (15-35 cm). Longer blades make it easier to reach higher branches, so consider this when choosing a hedge trimmer.
- Blade type: Most hedge trimmers have either a dual-action or single-action blade. Dual action blades are designed to cut on both the up and down stroke, making them ideal for tougher branches. Single action blades, however, only cut on the upstroke and are better suited for more delicate hedge trimming tasks.
- Adjustable handle: An adjustable handle can make it easier to reach awkward angles or hard-to-reach places in your garden. Many hedge trimmers also come with an ergonomic design to make them easier and safer to use.
- Safety features: A good hedge trimmer should always be equipped with safety features such as a blade guard, trigger lock and anti-vibration technology. These features help to make sure that the trimmer is used safely and effectively. 
With these features in mind, you should have no problem finding a hedge trimmer that works best for your needs.
Hedge trimmer blade types
There are several different types of blades for a hedge trimmer. The most common blade type is the dual-action blade, which features two reciprocating blades that move in opposite directions to make cutting faster and easier. This is usually the best choice for trimming smaller hedges where accuracy is important.
You can also find rotary blade models that use high-speed rotating blades to make cutting through bigger, denser hedges much quicker. Another option is the single-sided blade, which uses a single straight edge with serrated teeth to tackle larger hedges in one pass. Whichever type you decide on, be sure to pick up an accessory kit so you have everything you need to keep your hedge trimmer running smoothly!
Hedge trimmer operation
Once you have set up your hedge trimmer, it is time to start using it. To ensure a safe and successful trim, follow these steps:
- Put on the correct safety gear. This includes protective eye goggles or glasses, as well as gloves and long pants.
- Start the engine. Most hedge trimmers are equipped with either a two-stroke or four-stroke gasoline engine that needs to be started before use. Read the instructions manual for more detailed instructions about starting the engine of your specific model of hedge trimmer.
- Adjust the cutter angle if necessary – some models allow for adjustment of the blades to make trimming easier in tight spots or around curved edges.
- Hold the trimmer with both hands and start trimming. Always make sure to keep your arms in a comfortable position, and never force the blade through obstacles like branches or stones.
- Move the blades slowly but steadily across branches or foliage. Keep the blades close to the surface of whatever you are cutting so that it is cut evenly and neatly.
- After finishing one area, switch off the engine and wait for all moving parts to stop completely before continuing with another area!
- It is also important to maintain your hedge trimmer regularly – make sure to check that all parts are free from dirt and debris, sharpen blades when necessary and replace any worn out parts as soon as possible.
- When you are finished, store your hedge trimmer in a safe and secure area to protect it from damage or theft.
Following the steps above will help ensure that you get the best out of your hedge trimmer and keep it in top condition for years to come!
How does a hedge trimmer work?
Hedge trimmers work by rapidly moving a set of sharp blades back and forth to cut through branches. The blades are powered either electrically or via gasoline, depending on the type of hedge trimmer being used. Electric models typically require an extension cord while gas-powered versions offer greater range and maneuverability.
When using a hedge trimmer, it is important to wear protective clothing such as long pants, closed-toe shoes, safety glasses, and gloves to protect from debris that may be thrown back at you during use. It is also important to avoid cutting branches thicker than the blade can handle as this could damage the motor or cause other safety issues.
Everything you’ll need to finish the job

What to look out for when buying a hedge trimmer?
When buying a hedge trimmer, it is important to consider its features and capabilities. Factors such as blade length, power source, weight, handle design, and anti-vibration technology should all be considered. It’s also important to check the warranty on the product – some are more comprehensive than others. Additionally, reviews from other customers can be a great way to get an idea of how well a particular model performs in real-life situations. 
What is the best wattage for a hedge trimmer?
The best wattage for a hedge trimmer will depend on the size of your hedges and the power you need. For smaller hedges, a trimmer with 500-600 watts should be sufficient, while larger hedges may require more power. If you’re using a corded model, look for one with at least 1000 watts to provide enough power to get through tough branches. Cordless models are usually lighter and more portable than their corded counterparts, but they also tend to have lower wattages – typically ranging from 20 to 40 volts. When it comes to choosing the right wattage for your hedge trimmer, make sure you opt for one that is powerful enough to handle your job without having to work too hard. 
How big of a hedge trimmer do I need?
When it comes to picking the right size of hedge trimmer, it largely depends on the size and type of hedges you intend to trim. If you have small or delicate hedges like boxwoods and yews, a smaller hedge trimmer with less power is more suitable. For larger hedges such as privets, hollies, or evergreens, a larger and more powerful hedge trimmer will be required. It’s important to know that the thicker the branches are that your hedge trimmer needs to cut through, the higher wattage motor you should look for when selecting a model. A higher wattage motor will give you more power and provide better cutting performance. Additionally, longer blades also help reduce vibration, which can make trimming easier on your hands.
Another factor to consider when selecting a hedge trimmer is the type of blade used. Most electric models feature blades made from either plastic or metal alloy. Plastic blades tend to be less durable and should only be used for small hedges with thin branches. Metal alloy blades are typically more durable and better suited for larger hedges with thicker branches.
By taking into consideration the size and type of hedges you intend to trim, as well as the blade material and motor wattage, you’ll be able to select the right hedge trimmer size for your needs. With proper care and maintenance, this tool will provide years of reliable service!
