Grass trimmer buying guide

Grass trimmers are not only the perfect tool for keeping the edges of your lawn looking neat and tidy, they’re also brilliant for getting to those parts of your garden that a lawn mower just can’t reach. This guide will help you find the right grass trimmer to smarten up your garden.

What types of grass trimmers can you choose from?


A rechargeable battery means you aren't limited by the length of a power cable and can take this trimmer anywhere – perfect if you need to work on areas of your garden that are further away from your house. Of course, you’ll need to make sure the battery is charged for a few hours before using it, so you have to plan ahead first. If you have a bigger garden, it’s worth buying a second battery so you can keep on using your trimmer while the other one charges.


Electric trimmers run off the mains electricity, so offer unlimited power and easy manoeuvrability, making them a convenient and practical choice for most people. You might need to use an extension lead depending on the size of your garden, just and make sure you use an RCD power adapter in case you accidentally cut through the cord.


These models are the most powerful sort of grass trimmers you can buy, making them perfect for heavy-duty jobs,large gardens and overgrown areas. However, they are heavier and not as easy to manoeuvre, so if you have a smaller garden you’ll probably find you’re better off choosing a battery or electric powered model.

How do they work?

Most grass trimmers don’t actually use a blade, and instead feature a line of nylon cord that clips into the trimmer’s head and spins at high speed, cutting through grass and vegetation with ease. With some trimmers you’ll need to change the cord when it wears out or breaks. Others have an integral cord spool that feeds through automatically, meaning you only need to replace it when the spool runs out.

Other things to look out for include models with a dual line, which offer increased cutting power that makes them perfect for dealing with particularly overgrown areas of your garden, meanwhile a rotating head that turns 180° will do a great job of keeping the edges of your lawn trim.

Adjusting your trimmer

You’ll want to make sure you will be comfortable while using your grass trimmer, especially if you plan on using it for lengthy periods of time, so it’s worth making sure you buy a model that suits your height. Plenty of trimmers come with an extendable shaft that adjusts to suit your height, so you won’t have to stoop while you’re working.

Some trimmers also have pivoting heads which make it easier when you’re enables easy edging and or cutting under hedges and obstacles like garden furniture. You might also find it useful to look at models that feature an auxiliary front handle, as this will help you keep the trimmer steady while in use and improve the comfort and accuracy of your work.

Keeping safe with your grass trimmer

As with all power tools, you’ll want to make sure you use your new grass trimmer safely. Follow these simple rules to avoid injury:

  • Wear safety goggles to protect your eyes from flying debris.
  • Wear heavy-duty footwear to protect your feet.
  • If you’re using an electric trimmer make sure the power outlet has RCD protection.
  • Don’t use an electric trimmer in wet weather.
