Hey there! Does your string trimmer sound like it’s just blowing air, without actually cutting anything? If so, you’ve probably run out of string. Don’t worry, it’s a common issue, and putting new string on is actually pretty simple once you know the ropes – or should I say, the string!
We understand it can seem a little intimidating at first. You might be wondering, “Which hole does it go in?” or “How do I wind it without making a tangled mess?” We get it! But trust us, with a few clear steps, you’ll be feeling like a pro in no time.
Think of it like tying your shoes. It seems complex at first, but after a few tries, you do it without even thinking. Let’s get your trimmer back to singing its cutting song!
How To Put String On Lawn Mower?
To put string on your lawn mower’s trimmer head, you generally remove the old spool or housing, feed new line through the appropriate holes, wind it tightly, and then reassemble the head.
Why Is Fresh Trimmer Line So Important?
A fresh, properly loaded trimmer line is like a sharp blade for your weed eater. It ensures clean cuts and efficient trimming. Old or brittle line breaks easily, making your yard work take much longer. You want that satisfying “whirring” sound, not a frustrating “thwack-snap” every few minutes!
Many experts say that using the correct line size and type for your trimmer also optimizes performance and reduces strain on the motor. We often found that thicker lines handle tougher weeds better, while thinner lines are great for lighter tasks.
Gather Your Tools First
Before you dive in, let’s make sure you have everything at hand. It’s like preparing ingredients before cooking; makes everything go smoother.
- New Trimmer Line: Check your trimmer’s manual for the correct diameter.
- Pliers or Scissors: For cutting and handling the line.
- Your Trimmer Manual (Optional but Recommended): Every model can be a little different.
- Gloves (Optional but Recommended): Protect your hands.
Safety First: Your Most Important Step
Alright, before we touch anything, let’s talk safety. This isn’t just a suggestion; it’s a rule! You’re dealing with a powerful tool, even when it’s off.
Always ensure your trimmer is completely off and unplugged (for electric models) or the spark plug boot is disconnected (for gas models). This prevents any accidental starts while your hands are near the cutting head. Think of it as hitting the pause button on potential trouble.
Understanding Your Trimmer Head
Most string trimmers use one of two main head types: “bump feed” or “manual feed.” Knowing yours will guide the string-loading process.
We often find that bump feed heads are the most common. These let you extend line by simply tapping the head on the ground while the trimmer runs. Manual feed heads, conversely, require you to stop and pull out more line by hand.
The “Bump Feed” Head Method (Common Type)
This is probably what you have! It’s designed for convenience, but can seem a bit tricky to load initially. Don’t worry, we’ll walk through it.
Clearing the Old String
First things first, let’s get rid of any old, broken line still stuck in there. Sometimes, you’ll just have tiny bits left. Other times, a knotted mess.
If there’s an old spool, remove it. Usually, you’ll find tabs on the side of the trimmer head that you squeeze to release the cover. Once the cover is off, lift out the spool. Toss any remaining old string; it’s done its job!
Preparing Your New Line
Cut a length of new trimmer line. How long? Many experts suggest around 15-20 feet for most spools. If you have a dual-line head, you might need two equal lengths, or one really long piece that you fold in half.
Find the midpoint of your line. If your spool has a split, like a channel down the middle, you’ll typically start by feeding the midpoint into that slot.
Feeding the Line Through
Some bump-feed heads are super easy and called “load-and-go” or “speed-feed.” With these, you just align the arrows on the head, push the line straight through until it’s even on both sides, then twist the knob to wind.
For traditional bump feeds, you’ll feed one end of the line through one eyelet on the spool, and the other end through the opposite eyelet. You want the line to sit securely in the center slot of the spool.
Winding It Right
This is where proper winding comes into play. If your spool has arrows, follow them! You want to wind the line neatly and tightly in the direction indicated. Many spools have two separate compartments for two lines. Wind each line separately and keep them tidy.
Wind it like you’re winding a fishing reel – no overlapping, no loose coils. Tight, even wraps are key to preventing tangles and ensuring smooth feeding (Briggs & Stratton).
Once wound, leave a few inches of line sticking out from each eyelet. Reattach the spool to the trimmer head, making sure the lines go through the metal eyelets on the outer casing.
Manual Feed Heads: A Simpler Approach
Manual heads are often more straightforward. You simply cut two pieces of line, usually around 8-12 inches each, and feed them through dedicated holes in the head. They often have a small knot or catch to hold the line in place. No winding involved here!
Troubleshooting Common Issues
Even with the best instructions, sometimes things don’t go perfectly. That’s okay! Let’s tackle a couple of common hiccups.
When Your String Won’t Feed
Is your line getting stuck or not bumping out? We found that this usually comes down to improper winding or old, fused line. If the line is tangled or too loose on the spool, it can’t feed properly.
Another reason could be debris inside the head. Take it apart, clean it thoroughly, and try rewinding the line, making sure it’s snug and even (Consumer Reports).
Line Breaking Too Often?
Frustrating, isn’t it? If your line keeps snapping, consider a few things. Are you using the correct line diameter for your trimmer? A line that’s too thin for tough jobs will break easily.
Also, check the eyelets on your trimmer head for wear. If they’re worn down or have sharp edges, they can fray and cut the line. Sometimes, it’s just about hitting too many hard objects like fences or concrete!
Maintenance Tips for a Longer-Lasting Head
A little care goes a long way in extending the life of your trimmer head and making string changes easier.
Keeping Your Trimmer Head Clean
Grass clippings, dirt, and sap can build up inside the trimmer head. This gunk can prevent the line from feeding smoothly and even jam the mechanism. Many experts recommend cleaning the head after every few uses.
Take it apart, brush out any debris, and ensure all moving parts are clear. This simple act can save you a lot of future headaches!
When to Replace the Head Entirely
Trimmer heads aren’t meant to last forever. If you notice cracks, excessive wear on the eyelets, or if the bump mechanism stops working, it might be time for a replacement. Some experts suggest that a head showing significant wear will make your trimmer less efficient, even with fresh line.
A new head can breathe new life into an otherwise perfectly good trimmer (Popular Mechanics).
Here’s a quick reference for common trimmer line sizes:
| Line Diameter (Inches) | Best Use Case |
|---|---|
| 0.065 – 0.080 | Light residential trimming, grass only |
| 0.080 – 0.105 | General yard work, light weeds, small brush |
| 0.110 – 0.130 | Heavy-duty residential, commercial, thick weeds |
Before you get back to trimming, let’s do a quick safety check:
- Is the string securely wound?
- Are the lines extended correctly from the eyelets?
- Is the trimmer head cover fully locked in place?
- Are your safety glasses ready?
- Is the area clear of people and pets?
Conclusion
You did it! Putting string on your lawn mower’s trimmer head might have felt like a big task, but with these steps, you’ve likely conquered it. Remember, practice makes perfect, and soon you’ll be able to reload your trimmer almost on autopilot. Enjoy that satisfying feeling of a well-groomed yard!
How do I know what size trimmer line to buy?
Always check your trimmer’s owner’s manual for the recommended line diameter. Using the wrong size can impact performance and even damage your trimmer over time. If you don’t have the manual, look for a sticker on the trimmer itself, or check the manufacturer’s website by model number.
Can I use any type of string in my trimmer?
While many lines are universal in terms of shape (round, square, star), the most important factor is the diameter. Ensure the line matches the recommended size for your trimmer. Different shapes and materials (like twisted or serrated) are designed for specific cutting tasks, but the diameter is non-negotiable.
Why does my trimmer line keep breaking inside the head?
Line breaking inside the head is often due to improper winding (too loose or overlapping), using old brittle line, or excessive buildup of dirt and debris inside the spool housing. Make sure to wind the line tightly and evenly, and clean the head regularly.
How often should I replace my trimmer line?
There’s no fixed schedule; it depends on how often you trim and what you’re cutting. You’ll know it’s time when your line consistently runs too short, or when you notice a significant drop in cutting performance. Always have a spare spool or roll of line ready.
Is there an easier way to load trimmer line?
Yes, some modern trimmers feature “speed-feed” or “load-and-go” heads that allow you to push a single length of line straight through the head without disassembling it, then twist a knob to wind. If you struggle with traditional methods, researching trimmers with these features might be a great option for your next purchase.
