Grass trimmer guide

A grass trimmer, or strimmer, is a useful tool for keeping your garden’s greenery tidy. Instead of a blade, they spin a nylon line at an incredibly fast speed. This makes them strong enough to make light work of grass, weeds and plants, without the risk of damage to driveways, fences and sheds.

Lawns

A grass trimmer is ideal for finishing off a cut lawn. It makes light work of any leftover strands, helping you achieve the perfect cut.

Borders and edges

It can be tricky to cut the edges of your lawn with a lawnmower. A trimmer makes it simple to tidy up the edges so that they match the rest of the lawn.

Weeding

Overgrown weeds can be a real pain to get rid of, but a grass trimmer can cut them down far more efficiently than doing it by hand.

Line guide

Most grass trimmers come with either a single or dual reel of line. Two lines can cut faster, and single lines are more suited to smaller lawns.

Bump feed - When the line starts becoming short, a bump feed system allows you to simply tap the head on the ground to release more line.

Automatic feed - This mechanic means more line will be given out automatically when it starts to become too short, meaning you don't need to worry about triggering it.
