The sweet scent of freshly cut grass. The satisfying whir of the engine. The feeling of accomplishment as your lawn transforms from unruly wilderness to a manicured masterpiece. But then, the dreaded snap. Your lawn mower string breaks, leaving you stranded in a sea of unkempt blades. Don’t despair! This guide will walk you through the process of putting your lawn mower string back on, ensuring a smooth return to your lawn care routine. We’ll cover everything from identifying the correct type of string to troubleshooting common problems, so you can get back to tackling those weeds in no time.
Essentially, replacing a broken string on a lawnmower involves unwinding the old string, installing the new one, and adjusting the tension for optimal cutting performance. Let’s get started!
Identifying the Right String
The first step is to determine the type of string your lawn mower needs. The most common types are:
- Round line: This is the classic string, often made from nylon or plastic. It’s affordable and suitable for general lawn maintenance.
- Square line: This string provides a more aggressive cut and is beneficial for tougher weeds or thicker grass.
To find out what your mower uses, check the manual or the underside of the cutting head. Look for a label or markings that indicate the recommended string type, diameter, and length.
Choosing the Right String Length
The optimal length of the string is crucial for proper operation. Here’s a breakdown:
Understanding the String Length Impact
- Too short: The string may not reach the ground, resulting in uneven cuts and difficulty mowing.
- Too long: The string can become tangled, causing the mower to stall or damage the cutting head.
Determining the Ideal Length
- Consult the manual: Your manual will specify the ideal string length for your mower model.
- Measure the spool: If you don’t have the manual, measure the diameter of the spool to determine the approximate length needed.
Replacing the String – Step-by-Step
Now, let’s dive into the practical steps of replacing your lawnmower string:
1. Disengage the Cutting Head
- Locate the release button on the cutting head. It’s usually a small button or lever near the bottom of the head.
- Press or pull the release button, and gently pull the cutting head away from the mower body.
2. Remove the Old String
- Once the cutting head is detached, carefully remove the old string from the spool.
- If the string is tangled, you might need to use a small tool like a pair of pliers or a screwdriver to help unwind it.
3. Insert the New String
- Wind the string around the spool: Start by placing the end of the string in the groove on the spool. Then, wind the string around the spool in a clockwise direction.
- Ensure even winding: Keep the string tension consistent as you wind to avoid uneven distribution.
- Secure the end: Once you’ve filled the spool, secure the end of the string by tucking it into a slot or holding it in place with a small piece of tape.
4. Reassemble the Cutting Head
- Slide the spool into the head: Gently push the spool back into the cutting head, ensuring it’s securely fitted.
- Reattach the head: Engage the release button and carefully slide the head back onto the mower body.
5. Adjust the String Tension
- Locate the tension adjustment knob: This knob is usually located on the side or bottom of the cutting head.
- Tighten the knob: Turn the knob clockwise to increase the tension. This will ensure that the string is held securely within the cutting head and prevents it from loosening during operation.
6. Test the Mower
- Start the mower: Ensure the safety switch is engaged and start the mower according to the manufacturer’s instructions.
- Check for smooth operation: Listen for any unusual noises or vibrations.
- Adjust string length: If the string is too long or short, you can easily adjust it by using the adjustment knob on the cutting head.
Troubleshooting Common Issues
- String not feeding out: Make sure the string is properly wound on the spool and that the tension adjustment knob is tightened securely. If the string is still not feeding out, you might need to check for any obstructions or debris in the cutting head.
- String breaking frequently: This could be due to a dull string, worn cutting head, or improper string length. Ensure you’re using the correct type and diameter of string for your mower, and consider replacing the cutting head if it’s showing signs of wear.
Safety Precautions
- Always disconnect the spark plug before working on the cutting head.
- Wear safety glasses and gloves to protect yourself from flying debris.
- Handle the string with care, as it can be sharp.
Conclusion
Putting a lawnmower string back on is a simple task that anyone can master. By following these straightforward steps and troubleshooting any potential problems, you can ensure a smooth and efficient mowing experience. Remember to use the correct type and length of string for your mower and adjust the tension for optimal performance. With a little care and attention, you’ll be back to enjoying a beautifully manicured lawn in no time.
FAQs
1. What is the purpose of the string on a lawn mower?
The string on a lawn mower, also known as the trimmer line, is what cuts the grass. It’s attached to a spool inside the trimmer head and is dispensed as needed. When the string hits something solid, it breaks and retracts back into the spool, preventing damage to the mower or surrounding objects.
The string is designed to be easily replaced when it wears down or breaks. You can buy new string specifically for your mower model, or find universal string that will fit most models.
2. How do I know if I need to replace the trimmer line?
There are a few signs that indicate it’s time to replace your trimmer line. The most obvious sign is when the string breaks or gets too short to cut grass effectively. You might also notice the string becoming frayed, thin, or uneven in length.
If you find that your mower is struggling to cut through grass, particularly thicker or tougher grass, it could be a sign that the string needs to be replaced.
3. What tools do I need to replace the trimmer line?
You’ll need a few basic tools to replace the trimmer line. The most essential is a screwdriver, specifically one that matches the screws on your trimmer head. You may also need a pair of wire cutters or scissors to trim the string to the correct length.
Lastly, you’ll need a new spool of trimmer line. Check your user manual for the correct size and type of line for your specific model, or purchase a universal line that fits most trimmers.
4. How do I remove the old trimmer line from the spool?
The process of removing the old trimmer line varies depending on the type of trimmer head you have. However, the basic steps are:
- Disengage the trimmer head: This is usually done by pressing a button or lever.
- Unscrew the trimmer head: Use your screwdriver to loosen and remove the screws that hold the trimmer head together.
- Remove the old line: Carefully pull the old line out of the spool.
Once the old line is removed, you can discard it and start attaching the new line.
5. How do I install the new trimmer line?
Once you have the old line removed, you can install the new line. This typically involves:
- Feeding the new line into the spool: You’ll need to follow the manufacturer’s instructions for feeding the line through the spool.
- Attaching the new line to the spool: Most spools have a mechanism for locking the line in place.
- Reassembling the trimmer head: Place the spool back in the trimmer head, tighten the screws, and engage the trimmer head.
6. What are some common mistakes to avoid when replacing trimmer line?
One common mistake is using the wrong type of line for your mower. Always consult your manual for the recommended line type and diameter. You may also encounter problems if you don’t feed the line correctly onto the spool.
Ensure the line is wound tightly and evenly on the spool to prevent tangling and ensure smooth operation.
7. Is there a way to prevent trimmer line from breaking?
While it’s impossible to prevent trimmer line from breaking completely, there are steps you can take to extend its lifespan. Use the recommended type and diameter of line for your mower.
Avoid running the trimmer over objects that could cause the line to break, and consider using a heavier-duty line if you frequently encounter obstacles like rocks or fences.
