The whirr of a gas-powered lawnmower or the hum of an electric one is a familiar sound of summer. But what happens when that familiar sound changes to a frantic rattling? Chances are, your lawnmower string needs replacing. This article will guide you through the process of replacing your lawnmower string, covering everything from identifying the right string to the final steps of reassembling your mower. Whether you’re a seasoned gardener or a novice lawn enthusiast, this guide will equip you with the knowledge to tackle this common lawn care task with ease.
In essence, replacing a lawnmower string is a relatively straightforward process. It involves removing the old string, measuring and cutting the new string, winding it onto the spool, and then reattaching the spool to the mower head. Let’s delve into the details of this process, step-by-step.
Identifying the Right String:
The first step to replacing your lawnmower string is to choose the correct type. There are several factors to consider when selecting a replacement string, including:
1. String Material:
- Nylon: The most common type of lawnmower string. It is affordable, durable, and works well on most types of grass.
- Square-shaped nylon: Offers a more precise cut and is often favored for edging.
- Monofilament: Known for its strength and ability to cut through tough weeds and brush.
- Twisted: A more durable option made from braided strands of nylon or other materials.
2. String Diameter:
The thickness of your string is essential for optimal cutting performance. Check the manufacturer’s recommendations or consult the user manual for your specific mower model. A thicker string is generally more durable but can be harder on the mower’s engine.
3. String Length:
You’ll need enough string to fill the spool, which varies depending on your mower’s design. You can measure the old string, but it’s often easier to buy a bulk pack of string that will last you several replacements.
Preparing Your Mower for String Replacement:
Once you have the right string, you can begin the process of replacing it.
1. Disconnecting Power:
The first step is to ensure your mower is disconnected from any power source. This is crucial for safety reasons. If your mower is gas-powered, remove the spark plug wire. For electric models, unplug the mower from the power outlet.
2. Identifying the Spool:
Locate the spool that holds the string. This is usually located underneath the mower head.
3. Removing the Old String:
Most lawnmower spools have a release button or a lever that needs to be pressed or pulled to release the spool from the mower head. Once released, you can pull the old string out.
Replacing the Lawn Mower String:
1. Winding the New String:
This is the most crucial step, as the winding pattern directly impacts the performance of your string. Most spools have a guide that will assist in winding the string correctly.
- Step 1: Hold the spool in your hand and feed the new string through the guides or slots.
- Step 2: Wind the string around the spool, following the direction of the arrows (if present) on the spool.
- Step 3: Be careful not to overwind the string, as this can cause it to break or jam during use.
2. Inserting the Spool:
Once the string is wound correctly, insert the spool back into the mower head. Make sure the spool is secured in place and the string is aligned with the feed slots or guides.
3. Replacing the Mower Head Cover:
Secure the mower head cover back into place.
4. Test the String:
Turn on your mower and carefully test the string to ensure it’s feeding correctly and cutting properly.
Additional Tips for Replacing Your Lawn Mower String:
- Wear safety glasses: This will protect your eyes from flying debris.
- Use a pair of pliers: If you have difficulty removing the old string or attaching the new one, use a pair of pliers to assist you.
- Consider using a string trimmer: If you have a lot of edging to do, consider using a string trimmer, which is designed specifically for edging.
- Always check the user manual: For specific instructions on how to replace the string for your particular model, consult the user manual.
Conclusion:
Replacing your lawnmower string is a quick and straightforward task that can save you time, money, and frustration. By following the steps outlined in this guide, you can easily ensure your lawnmower is equipped to tackle your next lawn care project. Remember to choose the right type of string for your needs, take your time with the winding process, and always prioritize safety. Happy mowing!
Frequently Asked Questions
What tools do I need to replace my lawnmower string?
You will need a few basic tools to replace your lawnmower string. First, you’ll need a Phillips head screwdriver to remove the housing that holds the string. Next, you’ll need a pair of wire cutters to cut the old string. Finally, you’ll need a new spool of lawnmower string. Be sure to choose the right type of string for your mower. Consult your owner’s manual for specific recommendations.
How do I know when to replace my lawnmower string?
You’ll know it’s time to replace your lawnmower string when it starts to fray, become thin, or when you hear a “thumping” sound as the mower runs. This thumping sound indicates the string is hitting the housing and not spinning freely. The string might also become brittle and break easily, causing your mower to be less efficient. If you notice any of these signs, it’s time to replace the string.
How much string do I need to cut?
The amount of string you need to cut will vary depending on the size and type of your lawnmower. Generally, you should cut a length of string that is about two to three inches longer than the diameter of the spool. It’s better to cut a little too much than too little, as you can always trim off any excess string once the new string is installed.
How do I insert the new string into the spool?
To insert the new string into the spool, you’ll need to wind it around the spool in a clockwise direction. Start by threading the end of the string through the hole in the spool. Then, hold the spool in your non-dominant hand, and use your dominant hand to wind the string around the spool. Make sure to keep the string tight as you wind it, and avoid overlapping the string.
What if my spool has a “button”?
Some lawnmower spools have a small “button” that helps to keep the string in place. To use this button, simply push it down as you wind the string around the spool. This will keep the string from unraveling as you work. Once the string is wound, the button will pop up, securing the string in place.
Can I use any type of string in my lawnmower?
The type of string you use in your lawnmower will depend on the type of mower you have and the type of grass you are cutting. Generally, you can use round, square, or braided string. Round string is the most common type, while square string is more durable. Braided string is best for thick grass and weeds. Consult your owner’s manual for specific string recommendations.
What if I can’t find the right replacement string?
If you can’t find the right replacement string for your lawnmower, you can try to use a similar type of string. Make sure the new string is the correct diameter and length for your spool. If you’re unsure, it’s best to contact the manufacturer of your lawnmower for assistance. They can advise you on what type of string is compatible with your specific model.
