What Is a Line Trimmer and What Is Its Purpose?

As human beings, we’re always inventing new tools and machines. Sometimes they just help make daily tasks easier – but often they completely change the way we deal with an issue or problem. For me, the line trimmer fits into this category.

In essence, it’s a piece of garden machinery that are used to tackle grass and vegetation where a lawnmower can’t reach. This can be through petrol, corded electricity, or battery-powered. Line trimmers have a head that rotates at high speeds which feeds out nylon cord. This line can be at varying thicknesses and efficiently cuts through green or soft vegetation as the head rotates. Some line trimmers have two pieces of cord, allowing double the cutting power. As you use the line to cut, it is gradually worn down. Some line trimmers automatically feed the cord as you use the machine, while others use a bump feed system. This allows you to tap the head of the machine on the ground so that you can determine the length of the cord.

What Areas Are You Trimming?

When you think about mowing your garden, visualise all the areas that your mower can’t reach. Such as right up against walls or fences – or around garden furniture or trees. This is where a line trimmer comes into use. Before line trimmers existed, these areas were either ignored or tackled with a pair of shears. This was back-breaking and tedious work. With a line trimmer, you can quickly and efficiently deal with these areas, creating a very professional and manicured look. I always recommend line trimming first – then any trimmings can be swept or blown off paths or patios back onto the lawn before you mow them up.

What Type of Line Trimmers Are Available?

But don’t get overwhelmed – they all help you keep your garden neat and tidy! The three main types of

Petrol Powered Line Trimmers

Using Lithium-Ion technology – the cordless battery line trimmers deliver ample power precisely when required, minus the noise and exhaust emissions typical of petrol engines.

The Webb WEELT650 Classic 650W 29cm Line Trimmer & Edger is a powerful and versatile tool. With its robust build and telescopic shaft, it effortlessly tackles overgrowth and transforms into a lawn edger with a simple twist of the head.

How To Use a Linetrimmer?

When using a line trimmer, allow the revolving head or spool to hover above the ground. Watch out for stones or loose material that could be flicked up and catapulted towards you or others. Also be sure to make sure the cord won’t get caught up in something, such as wire netting. Wear face, eye and ear protection – as well as gloves and suitable footwear. It’s also very important to be aware feeds out the nylon cord as it gradually wears down so that you can continuously cut. If you don’t take note to do this, you may have to keep stopping to take it out manually, which can be very fiddly and time-consuming.

With regards to the remainder of your lawn area – now we’re into spring, cut it a little and often. Start on the highest cut and gradually reduce the height over a few weeks. Feed your grass to give it a boost after winter and once the ground dries out think about aerating and scarifying as necessary

Essential Protective Gear for Line Trimmer Use

When using power tools, I would always prioritise safety by wearing the appropriate Personal Protective Equipment (PPE). For line trimmers, it’s essential to wear safety glasses and an EN 166 certified clear face visor to shield your eyes and face from debris. Additionally, opt for snug-fitting clothing that covers your legs and arms, along with suitable work gloves and safety boots.

Webb currently offers a Trimmer Safety Kit for only £15.99.

And just remember, with the lawnmower and line trimmer dream team, this year you can really achieve those professional results and know you’re always fully in control.
