How to Restrict a Weed Killer in 4 Simple Steps

Whether your garden is neat and tidy or a bit wild, weed trimmers can be very useful tools when vegetation becomes overgrown or appears where you don’t want it. Most models will need the line replaced from time to time, so knowing how to rearm your weed eater correctly and efficiently is essential. A new trimmer will likely come pre-strung with string and ready to go. If it comes without string, however, you can purchase pre-strung spools for it. (It’s also a good idea to have an extra pre-strung spool ready to go in case you run out of twine in the middle of a landscaping project.)

So what do you do if your trimmer comes without a string or you run out of string during a job? How exactly do you restrict it? Just follow these simple steps to get your garden back in shape.

Step 1: Delete the existing spool

Whether you’re starting with a pre-strung spool or going to refit your existing spool, you’ll need to remove it from the motor housing first. There are several ways your mower model can have the trimmer head or spool attached, but most will have two tabs that can be pushed in simultaneously. Some commercial models, however, will have screws that need to be removed with a screwdriver.

Step 2: cut the string to size

Before putting a new line back on the spool, you will need to determine the correct length of line and the number of pieces to cut. The amount needed will vary depending on the model of weeder you have. Small units will need less while large units will more often need more. The amount of twine can range from 8 feet to 25 feet, so it is best to know in advance the length of line to pre-cut. Some trimmers will have one cord while others will have two.

Step 3: Wind the line around the spool

With the spool removed and the string cut to size, the next step is to start winding the string onto the spool. The spool will have one or two holes in which to insert the end of the rope or ropes and hold it in place. The spool will indicate which way to start winding the string, usually an arrow. In the direction shown, start winding the string tightly around the spool. If your trimmer has two strings, wrap both at the same time, taking care to keep each in its individual valley without crossing each other. Winding the string carefully into the spool will ensure that it passes easily through the correct mechanism. Some spools will have extra notches to hold the string in place until it is attached to the trimmer.

Step 4: Attach the reel to the trimmer

Finally, attach the spool to the cutting head and slide the string through the guide holes in the device. You can leave around 5 inches of string to start with, but the initial length isn’t particularly important as it will adjust when the mower is turned on and tapped against the ground. Any excess line will be cut.

Inevitably, there will be variations between brands and models of trimmers. This is why it is very important to read the user manual before using any new equipment. As there are many types of trimmers, there are also many types of strings to choose from. Choosing the right gauge will keep the trimmer working properly and will not only extend the life of the line, but also the life of the trimmer. As with any gardening tool or machine, always follow safety precautions and double check your work.
