How to Replace Trimmer Line?

A string trimmer is a great way to maintain and care for your lawn. And luckily, most models require very little maintenance. But whether you own an electric or gas-powered trimmer, the one task you’ll certainly have to do is replace the trimmer’s line. Thankfully, this is an incredibly easy project that you can accomplish in just a few minutes. Besides replacing your trimmer line whenever the spool is depleted, you should also replace it at the beginning of each season since your old line can turn brittle over the winter and will break easily.

Brittle line will also wear down faster than fresh line when you use it on thick weeds or harder surfaces. Most models are built with a dual-line design and are fed by bumping the head. Even if your model uses an automatic feed, most of the steps will be fairly similar, though you should consult with your owner’s manual in order to make note of any different steps involved.

How to Restring Dual-Sided Spool?

To replace the trimmer line on a conventional bump head model, you need to disassemble the round, black cutting head of your tool. The first thing you need to do is prep your new string trimmer line by cutting 10 feet of replacement line. You can choose to use a twin-strand split line or even cut two pieces of trimmer line to 10’ each. Now, you want to disassemble the cutting head of your trimmer by unscrewing the bump knob and taking the inner wheel and spring out from the housing.

To install the new line, look for the two holes located at the top of your inner reel. Choose one of these holes and place both ends of the line into it. Then just pull the line completely through until only 2 to 3 inches remain. Next, you want to loop the short ends of the trimmer line through the second hole and close the loop by pulling the long end. Wind the new line around the wheel in the direction indicated by the arrow on top of the wheel, making sure that you keep it taut so that your line is wrapped evenly.

Once you only have around 6” left, simply push each string into the holding slots. With your line in place, simply reattach the spring to the tool’s shaft and feed the line through the spring head’s eyelets. Put the reel back into the shaft and align the eyelets on the spring head with the holding slots. Press the spring down and securely tighten the bump knob onto the trimmer head. Now, just pull the lines gently to ensure that they release from the holding slots. If the line comes out smoothly, your tool is properly loaded and ready to work.

Can you get Different Types of Trimmer Line?

There are actually several types of string trimmer line available. Which style is right for you will depend on the conditions that your tool will encounter and how you plan on using it. Rounded trimming lines are designed for everyday residential use, regardless of whether you have a small or large yard. While they can tackle virtually anything, they will tend to wear if you’re using it for large, heavy-duty applications but, since it’s also the most affordable line out there, that’s not really much of a concern.

You can get around 1800 feet of rounded line for about $20, which is why it’s normally the preferred trimmer string for most homeowners. Square line is best-suited for tackling heavy weeds. The square shape is big and thick and it’s capable of mowing down anything you throw at it. Due to the design of this line, it is relatively worry-free and can even scrape against rocks or trees with minimal wear. The downside to this style of line is that it is more expensive than rounded trimmer line.

Another type of string trimmer line is the 6-blade trimmer line which is made to stick to the end of high-wheel trimmers. This sort of line is used for professional landscaping since it is highly durable and can tackle any grass or weed conditions with ease. There is even titanium string trimmer line that is one of the most durable lines on the market.

These strings can take any abuse that you throw at them and deliver faster acceleration, better performance, and lower noise. While it certainly costs more than traditional rounded line, titanium line is designed to minimize the need for replacement.

What are the Benefits of String Trimmer Line Sizes?

Not only are there several styles of string trimmer lines out there, they also come in different sizes. While understanding all of the different diameters of line available might sound confusing, you can pretty much break them up in ranges based on the thickness of weeds that they’re capable of tackling. Small weeds can be easily trimmed with trimmer line that measures between 0.60 and 0.80 inches in diameter. Medium weeds are best trimmed with line measuring between 0.80 and 0.110 inches in diameter.

And any line with a diameter of more than 0.115 inches is great for large weeds. So if you’re just doing residential maintenance such as whacking weeds along your front lawn, driveway, and home, a small diameter line that measures between 0.60 and 0.80 inches is perfect for you. But if your home has large gardens and some thicker patches of weeds, you’re better off using a medium-sized line that measures between 0.80 and 0.110 inches.

You really will never have to purchase line that has a larger diameter than this unless you are getting into professional landscaping. The only other thing to remember before buying line of any particular size is to consult your models instruction manual. Many models only accept certain types and sizes of line so it’s advisable to make sure that the line you buy is compatible with your string trimmer.

With a little regular maintenance such as replacing your trimmer line at the beginning of the cutting season, a string trimmer is one of the most versatile tools that you can buy to maintain your lawn. And with a number of styles and sizes available, choosing the cutting line that is perfect for your needs is incredibly simple.
