In our years of testing line trimmers (also known as whipper snippers, string trimmers, strimmers, lawn trimmers and weed eaters), we've found that petrol models are your best option for big yards. However, cordless battery-powered models are becoming an alternative to consider. Electric models should only be reserved for smaller yards. 

Read our buying guide to find out what to look for when you're shopping for a line trimmer and how to get the best out of the one you have. Our how we test article details how we go about putting line trimmers through their paces.

Note: The Makita ER2600L and Makita EM2600U that we've tested have been subject to a product recall

Ease of use score

Expand to view more details.

We assess how comfortable the trimmers are to use, taking into account their weight, balance, handles, angle of the cutting head and so on. Respooling the line, using controls, starting, using the line feed and vibration are also taken into account.

Makes the trimmer easier to carry and use, especially for long jobs.

Allows you to adjust the shaft length. Usually only available on electric or cordless models as their motor is in the head, so there's no drive shaft in the tube.

A small projection – wire, metal or plastic – which helps you achieve a clean straight edge when trimming vertically. Usually acts as a tree guard in horizontal trimming.
