Step-by-step tips for how to use a weed eater

Knowing how to mow the lawn correctly will ensure your grass is in the best possible condition. Follow these steps on how to use a weed eater or string trimmer to make the process of keeping your lawn in great shape even easier. 

1. Know the safety practices

Just as it is when using your lawn mower, number one in importance when you’re getting savvy about how to use a weed eater is safety. Both debris and grass fly around when you are using it. ‘Make sure to wear safety glasses, shoes, and gloves to avoid any potential accidents,’ says Helene Keary, assistant marketing manager, Ryobi (opens in new tab).

2. Position the trimmer and your body

It’s important to understand the cutting head before you start learning how to use a strimmer. ‘You need to become aware of the direction in which the trimmer line will spin,’ says Helene Keary. ‘If it goes in an anti-clockwise direction, the grass will be thrown out to the left, so you need to position your body accordingly.’

Holding the equipment correctly is crucial. ‘It should be held just above the ground at an angle so that debris deflects away from you,’ says Ryan Patterson, Husqvarna (opens in new tab) consumer segment manager.

3. Work carefully

Begin trimming your lawn, but make sure you work with care. ‘It’s important to let the line do the work,’ says Ryan Patterson. ‘Never press the line into the ground or trimming area and make sure you have a steady hand, keeping the trimming pace slow.’

Cutting the grass on a flat surface? ‘You’ll want to hold the trimmer level against the surface,’ says Helene Keary.

Pay attention to planting – you don't want to be causing damage to your garden borders. ‘You need to be especially careful when working around plants,’ Ryan adds. ‘You should consider shortening your line to about 5 inches (13cm) and reduce the engine speed. Never make any adjustments to your line without turning the engine off first.’

Working on long grass? ‘For longer grass, trim the top first, repeating until you have the grass at your preferred length,’ he recommends.

4. Tackle edges

You may be using your weed eater as an edger, too to help neaten your lawn edging ideas. ‘This application can be more taxing on the unit than just trimming tall grass, so it is important to use the tools properly for consistent results and the best longevity of the tool,’ says Will Hudson, portable outdoor power sr. merchant at The Home Depot (opens in new tab).

‘Be careful when holding the trimmer so the head is in a vertical position. The goal is to run the line between the grass and concrete when edging along a sidewalk or driveway, or to keep the line on the edge of the grass when edging along a flowerbed. Try not to cut into the grass as it will cause scalping and possible long-term scarring and damage to your lawn.’

5. Cut thick grass and vegetation

Using a brush cutter attachment? ‘This is going to help you cut down thick grass and vegetation that have grown out of control,’ says Helene Keary. ‘In this instance, the tool should be used in long, sweeping motions.’

How to get the best from a weed eater

To get the best from a weed eater, consider both electric and gas-powered versions. 

‘If you are trimming grass far away from your house or require more freedom, consider a gas trimmer,’ says Ryan Patterson. ‘For easier handling, simpler maintenance and a quieter cut, a cordless battery grass trimmer is great for medium to large gardens while remaining as powerful as gas.’

For edging as well as trimming, you might want to invest in a tool that makes this easier. ‘Purchasing a string trimmer that rotates for easy edging or has an edging guide will help ensure you get a clean cut to your edges,’ says Will Hudson. ‘Attachment-capable trimmers are also a great option for dedicated edging.’

Maintenance is an important element of how to use a strimmer if your weed eater is to last well. Use these tips from Ryan:
