All grass trimmers have a motor that triggers the rotary motion of the nylon line and spool. Some strimmers have an auto-feed mechanism that feeds a string through the strimmer head if it wears out. This saves you from the trouble of pulling the string manually from the stringer head. Strimmers also come with a spool that holds the trimming line.

Grass trimmers are powered by different types of fuel. For instance, some grass trimmers are powered by petrol, while others are powered by electricity (i.e., electric strimmer). Battery-powered line trimmers have batteries that offer you different battery capacities. Due to this, may have different features.

Not to mention, the cutting power may differ from one product to another. Some may have a higher cutting power than others. The difference between such strimmer is not big. Take some time to study the different features of your brushcutters.

Precautions to Take When Using Strimmers

Below are important things to remember when using strimmers.

Be on the Lookout for Long Wires

If you are using a brushcutter with a long cable, you should keep the cable away from the trimming line as you are cutting turf. It would help if you also were keen and not walk blindly while cutting grass as you might trip and fall. Apart from that, it would help if you did not work in a wet area. It might be quite risky.

Protect Your Flowerbed

A strimmer can cut and ruin your flower bed quite fast. You should be cautious when using this machine as you are cutting grass near a flowerbed. Apart from that, it would be best to be extra careful as you are cutting near a wall. A grass trimmer can strip off bits of cement from the wall.

Do Not Use It in An Enclosed Space

A petrol-powered strimmer emits carbon monoxide—a hazardous gas that can harm your body. Using petrol grass trimmers or brushcutters in an enclosed area is dangerous. If you are planning to use it in an enclosed space, remember to open all the windows.

Once you finish cutting, store your petrol string trimmer in a safe place. Please keep it away from fire and any other material that may start a fire.

Step-by-Step Guide to Using a String Trimmer

Step 1: Wear Protective Gear

A cutting line cuts unwanted growths in a rotary motion. Some string trimmers have a speed of 2,500 rotations per minute. Due to this, the trimmer head can throw different types of debris in different directions.

To prevent any accidents from happening, you have to wear protective gear. Wear a pair of gloves and shoes made from a strong material. You should also wear a helmet that covers your face entirely. When it comes to safety gear, always choose the product the offers both durability and a high level of protection.

Apart from that, you should wear a pair of trousers while you are clearing turf with a strimmer in your hand.

Step 2: Remove Any Stones in Your Garden or Cut Area

If a string trimmer comes into contact with a stone, it might throw it in different directions and cause havoc. You have to remove the stones that might be in your lawn or garden. You should also get rid of the stones along the cut path to prevent damage to the tips.

You should also remove the obstructions in your garden. Examples of such obstructions include garden furniture and gardening tools.

Step 3: Start the Grass Strimmer

The next thing that you need to do is to start the strimmer. Since brushcutters have different designs, the start mechanism might differ from one strimmer to another. However, most trimmers have a power switch that allows you to start the motor.

Not to mention, brush cutters come with a manual that guides you in this process.

Step 4: Check the Direction of the Rotation

A strimmer displaces grass in different directions, depending on the rotation of the trimming line. For example, if a trimmer line rotates in a clockwise direction, it will displace debris towards the strimmer’s right side.

Using this type of grass trimmer, you have cut from the right side towards the left side. This gives you a better view of the area that you are working on. Moving your grass trimmer towards the right side might be challenging if it’s your first time using the tool.

Step 5: Make Sure the Tip Reaches the Grass

As mentioned earlier, a grass trimmer comes with a trimming line that makes it easier for you to cut grass. The tip of the trimmer is the part that cuts the grass. Hovering a strimmer over grass doesn’t do much.

For a brushcutter to cut effectively, the tip of the trimmer’s cutting head has to come into contact with the grass.

You can use a grass trimmer using four different cutting techniques; screeding, scything, edging, and tapering.

After that, start the brush cutter and walk along the garden’s edge to cut the grass that might be on that surface. While you might not get the perfect edge on your first attempt, the results will improve when you repeat this process.


Scything is a technique that makes it easier for you to cut around different types of obstacles. This technique also works when you’re strimming long grass before using a lawnmower.

This is the process of moving the grass trimmer from one end of your working space to the other end of your working space in a U shape. You can also overlap the previous scythes if you want to get an even and attractive cut. If you’re going to get a wavy finish, you separate the scythes.
