Maintaining a yard is hard work. Whether removing undergrowth, prune shrubs, clear sloped area, or tidy up garden edges, a conventional lawnmower is not enough; this is where a strimmer comes handy.

A Strimmer is a power tool that uses a high-speed rotating nylon line to cut and trim the grass. Shortened name of ‘string trimmer,’ a strimmer is designed to cut back tall grass, shrubs, and undergrowth and helps reach tricky areas, dense vegetation, or sloping ground. These machines feature a basic design and are easy to use and require minimal maintenance.  

How Does a Strimmer Work?

A strimmer uses a nylon line as it spins and cuts through the grass, weeds, and brush. The faster it spins, the more effective it is; the end of the line spin the fastest hence are the most effective cutting points. The line is held taught by the spinning motion of the spool, and centrifugal force. Therefore, the quicker the reel turns, the more taught the line would be, and the more effective it will be at cutting.

Types of Strimmers

There are three main types of strimmers, electric mains powered, battery-powered, and petrol powered.

Electric Strimmers

Electric Strimmers are powered by electric mains and are ideal for small gardens with the option of electrical sockets outside. They can also be used with an extension lead.  Electric strimmers do not require charging; hence they are more convenient than the battery-powered models.

The cutting width of electric strimmers varies from 25–40 cm. They have the apparent constraint that they need to operate near a power socket and slightly inconvenient to work with cables. These machines are lighter and cheaper, but comparatively not as powerful.

Battery Strimmers

Battery-powered strimmers are convenient to use and maneuver, and can easily reach tricky locations.  Battery-powered strimmers are lightweight, making them suited for the elderly or people who don’t like to operate bulky tools. Since they are battery powered, they can be used without a power source, making them more convenient. The primary disadvantage of battery-powered strimmers is that they need recharging. Most battery strimmers machines can operate for approximately 20 minutes on a standard charge. However, expensive models with larger batteries are available, and you can also buy interchangeable batteries to extend the operating time.

Petrol Strimmers

Petrol-powered strimmers encompass the most powerful engines and thus provide the highest performance in trimming, excelling all the alternative opponents.

They generally have a two-stroke engine to power the head, which can have a nylon grass trimming spool.  These machines are meant for heavy-duty clearing work and can easily handle any task, from long thick grass and tough weeds.  Petrol strimmers are portable, convenient to use, and don’t require long charging time like battery-powered strimmers, especially handy for using away from home and in extensive garden areas. Petrol strimmers are also lightweight, and many have separate attachments that are interchangeable, enabling you to complete a variety of different garden tasks. For a large garden, petrol strimmer is the best option.

Petrol strimmer also has drawbacks; they tend to be rather heavy, making them difficult to operate; furthermore, fumes, noise, and vibrations may be off-putting to others.  While these machines are inexpensive to buy, they require fuel, which adds to the running cost.

Features to look in Petrol Strimmers

Weight: Petrol strimmers are comparatively heavier than their electric counterparts. Ensure how much machine weight you can handle, and the duration of operation as a heavy strimmer may be challenging to use. Many heavier models come equipped with ergonomic handles and a carry strap, making it comfortable to use.

Shaft: This is the “pole” connecting the motor at one end to the head as the other. They can be straight or bent and are mostly separated into 2 (or possibly more) parts to make storage easier. The shaft of a petrol strimmer is typically straight, curved, or split. Each design has its benefit and maintenance requirements. For example, bent shafts make strimming large areas more comfortable, while straight shafts tend to be less convenient but offer more cutting power. Split shafts are great for multi-purpose maintenance, as they are designed to work with various attachments.

Cutting Width:  The cutting width of a strimmer impacts its suitability for specific tasks. Many strimmers are available with an adjustable cutting width ranging from 25cm up to around 50cm. The larger the cutting width, the higher the amount of grass it can cut at once, which is excellent if you have a large area of grass that needs work. 

However, if you have a garden with lots of flower beds and obstacles, a narrower cutting width will be better to prevent you from accidentally destroying them!

Line Feed: Three types of line feed are available on petrol strimmers – bump feed, fixed head feed, and automatic feed. With bump feed, you simply bump the base of the strimmer to release the line, while automatic feeds do so without prompting. However, automatics can be unreliable unless featured in high-end models that utilize better technology. These two feeds require spooling before use, but fixed heads mean you need to introduce a new line any time the previous one breaks, which is quite a nuisance as you need to stop mid-strimming. For this reason, it’s best to look for automatic or bump feed lines in a petrol strimmer.

Handle:  Strimmer handle should be ergonomically designed and easy to grip for comfort and safety. Many strimmers feature bicycle handlebar style handles, which distribute the load evenly.

Nylon line: Double-line nylon head is ideal for grass, soft plants, and finishing off a lawn, while a quadruple-line nylon head is better equipped for dense grass and small shrubs.

Cutting Guard: The cutting guard is designed to protect the user from flying debris thrown by the machine when used.

Spool: The spool is attached to the head of the grass trimmer to store that trimming line. If more range is required, it can be taken from the spool.  Most of the strimmers employ a “bump system,” where the spool is pressed gently on the ground while the strimmer is used to release a little more line.

Line Cutter: Line cutter is a small blade attached to the guard, that cuts the trimming line. It is designed to stop too much line being released when the spool is bumped; else, the motor will not be able to turn the head efficiently, or worse, the line may get entangled or cuts something it shouldn’t.

Bonus Tips – While Using Strimmers

Safety Equipment

Watch out for flying debris when using a blade head. Use safety equipment such as gloves, safety goggles, a visor, or even a helmet while operating the machine.  Strimmers are relatively noisy tools, hence noise-canceling headphones or earplugs are essential. Make sure you wear safety shoes to ensure your feet are adequately protected.

General Maintenance

The cutting surface of strimmers must be cleaned thoroughly after use. Debris such as leaves, et grass left on the machine can damage the metal parts. It is also essential to periodically check the tightness of the cutting head.

Check the oil level, air filter condition, and fuel level of the strimmer before use. Ensure that the air filter is not clogged by debris. It is ideal for cleaning the air filter every time you refill the petrol tank. Regularly check the spark plug of the strimmer. Once a year, change the spark plug, bleed the engine, and check the drive belts’ condition.

Before starting the motor after a long time, check the spark plug, they should have a biscuit brown colors. If it shows blackish color on the tip, then it should be cleaned or replaced. Strimmer nylon lines should be removed and stored separately in a cup or small bowl of water.
