Add a finishing touch to your lawn by cutting long grass and trimming the edges with a grass trimmer or a brushcutter.
Lightweight and easy to manoeuvre, grass trimmers are great for accessing areas that your lawnmower can’t reach. They’re also ideal for tidying around fragile areas of the garden such as around plants, trees or the borders of your lawn. A brushcutter is a heavier weight and more powerful machine, suitable for clearing overgrown grass, weeds, brambles and small hedges.
There are a number of types and models available and choosing one can be difficult. So let's breakdown the options for buying a new or replacement grass trimmer or brushcutter.
When choosing a grass trimmer or brushcutter, ask yourself the following questions to help decide on the best option for you.
Firstly, think about what type of grass you'll be cutting most often. Will it be a grass lawn, or coarser, more overgrown vegetation? For trimming short to medium-length grass, tidying edges and reaching places where the lawnmower can’t, a grass trimmer is the best option. For long and overgrown grass, weeds and small trees, consider a brushcutter. Or if you're not sure what you'll be cutting, or are likely to have both grass and brush to cut, look out for machines that are both grass trimmers and brushcutters.
Knowing what you’ll be cutting will also determine how powerful you need your grass trimmer or brushcutter to be.
If you have a large garden or patch of land, or plan to trim far away from your house, consider an option that doesn’t have to be plugged into the mains, giving greater freedom of use and movement. Similarly, a lightweight option will help you stay comfortable for the duration of the task.
Also, consider how densely packed with plants your outdoor space is. For example, if you need to work around a lot of flowers, bushes or trees, a trimmer with a smaller head will allow you to do this without damaging them as easily.
There are three main power types of grass trimmer and brushcutter: corded electric, cordless electric (also known as battery-powered) and petrol.
Electric grass trimmers and brushcutters provide unlimited constant power so you don’t need to worry about how much fuel you have or whether you have enough charge in the battery. Easy to handle while still being powerful, corded grass trimmers don’t require much maintenance and are ideal for use close to the house (or wherever your power source is).
Being plugged into a mains electricity socket, you have to be aware of the trailing cord at all times for safety. Make sure that your outdoor power source, as well as any extension cables, have a residual current device (RCD) – these shut off power when there’s a fault or the cable is damaged, ensuring that you don’t get a shock.
If you don’t have easy access to a power source or would simply prefer the freedom to easily move around, then our battery-powered cordless trimmers are for you. Most models are lighter in weight than corded trimmers and can charge in as little as one hour. Low maintenance and quiet, cordless trimmers are ideal for medium and large size gardens and away from home, such as on an allotment.
For those with long grass, coarse weeds or rough vegetation, a petrol brushcutter or grass trimmer is perfect. They're powerful, portable and offer unrestricted movement.
Ours have a 2-stroke engine, which means they require fuel and oil to be mixed together before they can be used. Heavier and louder than other models, petrol trimmers need regular maintenance to keep them performing at their best.
When choosing your grass trimmer or brushcutter, look out for these technical specifications.
There are two types of cutting systems for grass trimmers and brushcutters: lines and blades.
The line cutting system is the most common on grass trimmers. A strong wire rotates extremely quickly to cut the grass and is held on with a spool within the head of the grass trimmer or brushcutter. This wire (or line) can become degraded with use, and so a fresh supply is needed to keep trimming with ease. Look out for grass trimmers with two lines, increasing the amount of grass cut at one time. There are three different ways to release extra line from the trimmer:
The blade cutting system is more common on higher-specification grass trimmers and on brushcutters. These blades rotate at high speed and are easy to change. They’re also less hands-on than line cutting systems and tend to be more durable.
Look out for grass trimmers with a Durablade cutting system (pictured). This blade is made from a nylon composite and automatically contracts when it hits a hard object. Because of this it can last longer than other blades and ensures fewer interruptions during use.
Some brushcutters have interchangeable blades and wires. Use blades for longer grass, shrubs and weeds, or change to a line when trimming shorter grass and around delicate areas.
Measured in millimetres (mm)
The size of your trimming area determines the size you need - the bigger the cutting width, the more grass the trimmer can effectively clear in one go. Larger cutting widths will make cutting large areas quicker, but are not the best choice for smaller, hard-to-reach areas.
As a general rule:
Measured in watts (W) or volts (V)
When it comes to electric motors, the bigger the power output, the more powerful the trimmer motor will be – allowing them to deal with thicker grass. Electric motor power is measured in watts, while cordless battery power is measured in volts.
If you’re looking to use a trimmer on a small lawn, or for light use, electric models from 250 to 400W or cordless models with 12V and above will be suitable. For larger lawns with difficult areas, more power will be required – opt for a cordless electric model above 14V, a corded trimmer above 450V or a petrol model. The most powerful option is a petrol brushcutter.
Measured in ampere hours (Ah) or amp rating
The batteries of cordless products are measured in Amperes (Ah), this dictates the runtime that the battery will give you. The higher the capacity, the longer the battery will run for. The majority of our grass trimmer and brushcutter batteries are lithium-ion, which ensure no self-discharge when in storage and are therefore always ready for use.
Look out for grass trimmers and brushcutters that are supplied with batteries which can be used with other power tools, including drills, jigsaws, lawnmowers and hedge trimmers.
Measured in cubic centimetres (cc)
The bigger the number of cubic centimetres, the more powerful your petrol grass trimmer or brushcutter will be. More power is deployed to the cutting head, enabling it to deal with tougher jobs like thicker grass or weeds. Usually, the larger the engine, the heavier the tool is, so bear that in mind when choosing your petrol model.
Measured in litres (L)
The larger the tank, the more petrol your grass trimmer or brushcutter can store. This means that you can trim for longer without having to fill up. However, a bigger cubic capacity means that it will need more petrol to power it and this affects how quickly the fuel is used.
Measured in metres (m)
If you've opted for a corded electric grass trimmer or brushcutter, you'll have to keep an eye on the cable when trimming. For greater reach and mobility, opt for ones with the longest cable length available. Ours span up to 10m in length.
Measured in kilograms (kg)
Grass trimmers and brushcutters require lifting and, depending on the job, this could take quite some time. Be sure to choose a weight that you can comfortably manage for the duration.
In addition to the technical specifications, look out for extra features to make your task easier, quicker and more comfortable. Not all models will have all of these features, and some are specific to either grass trimmers or brushcutters – check the product details.
There are a number of handle types available to help you stay comfortable when trimming. These include different shapes, such as loop and "D" and features like soft-grip, ergonomic design and adjustable length. This extendable quality found on telescopic handles allows you to adjust the height of the grass trimmer to your height, making sure that it’s in a position that is comfortable for you. And for easy handling in any position, consider a grass trimmer with a secondary handle for extra stability.
The most powerful and heaviest brushcutters have dual handles to make manoeuvring easier and more comfortable by reducing strain on the back.
Larger and heavier models can come with a shoulder strap or harness. This makes it easier to hold up and move around the machine without getting backache and tired arms.
A plant protector is a square or curved piece of thin metal attached to the front of the grass trimmer or brushcutter. It ensures that your plants aren't damaged while you are working by holding back the plants from the line or blade. It also keeps the blade away from hard obstacles like walls and fences. Choose a grass trimmer or brushcutter with a plant protector if you have a garden with lots of planted borders and shrubbery.
Some grass trimmers and brushcutters come with a one-click rotating head, so you can effortlessly switch between trimming and edging functions. This is a great time-saving feature for busy gardeners.
Stock up on those extra bits and pieces that complement your grass trimmer or brushcutter.
It's important to wear safety goggles, gloves and sturdy shoes when operating a grass trimmer or brushcutter. These protect you from anything, such as small obstacles like sticks and stones, that could be thrown out by the grass trimmer when trimming.
If you’re looking for more manoeuvrability with your corded grass trimmer, pick up an outdoor extension cable or cable reels so that you can trim further into the garden. Always make sure your power outlet has RCD protection, as this will cut off the electricity in case you run over the cable or there’s a fault.
If you want to work without unwanted breaks while your battery recharges, pick up an extra battery. This means you’ll always have one charged and ready to go.
There are a few essential accessories for your petrol grass trimmer or brushcutter. These include products to mix the fuel for 2-stroke engines and to dispense it into the machine.
