The whirring of your lawn mower suddenly stops, replaced by a frustrating silence. You glance down to see a limp, broken string dangling from the head. It’s a classic lawn mower mishap, and one that can leave your lawn looking overgrown and your temper frayed. But fear not! Fixing a string on a lawn mower is a simple task that anyone can handle, and this guide will walk you through the process step-by-step.
This article will cover everything you need to know about fixing a broken string on your lawn mower, from understanding the different types of string heads to identifying the source of the problem and finally, replacing the string itself.
Understanding Your String Head
Before diving into the repair, it’s important to understand the type of string head you have. Lawn mowers come equipped with various string head designs, each with its own quirks and advantages. The two most common types are:
1. Bump Head: These heads have a simple design with a button that you tap against the ground to feed out more string. They are the most widely used and budget-friendly option.
2. Automatic Feed Head: As the name suggests, these heads automatically feed out string as needed, eliminating the need to manually adjust it. However, they can be more complex and require a bit more attention when replacing the string.
Troubleshooting: Why is My String Breaking?
Before you start dismantling your string head, it’s a good idea to identify the source of the problem. Here are some common culprits:
1. Worn or Damaged String: Just like any other tool, lawn mower string can wear down with use. If the string is frayed, tangled, or thin, it’s likely to break easily.
2. Improper String Length: A string that’s too long or too short can cause problems. Too long, and it can become tangled or caught in the mower’s housing. Too short, and it won’t be able to cut the grass effectively.
3. Obstacles and Debris: Stones, twigs, or other debris can easily damage the string or cause it to snap.
4. String Head Issues: The string head itself might be damaged or malfunctioning, preventing the string from feeding properly.
Replacing the String: A Step-by-Step Guide
Once you’ve identified the culprit behind your broken string, it’s time to fix it! Here’s a detailed guide for replacing the string on a standard bump head:
1. Gather Your Supplies:
- New String: Choose the right type and thickness of string for your lawn mower. Refer to your user manual or check the string head for recommended specifications.
- Scissors or a Knife: This will help you cut the string to the proper length.
- Flat-Head Screwdriver: Some bump heads have screws that need to be loosened before removing the string spool.
- Gloves: These will protect your hands while working with sharp edges.
2. Prepare the String Head:
- Remove the String Cover: Locate the string head cover, usually secured with a clip or a few screws. Carefully remove it to access the string spool.
- Remove the Old String: Pull out the remaining string from the spool. If it’s tangled, try to carefully untangle it as much as possible.
3. Load the New String:
- Cut the String: Measure and cut two pieces of string, each slightly longer than the diameter of the string head.
- Wind the String: Thread the ends of the string through the holes on the spool, making sure they’re facing the same direction. Then, start winding the string around the spool, keeping it tight and even. Secure the ends of the string in place.
4. Secure the String Head:
- Insert the Spool: Place the loaded string spool back into the string head, ensuring it’s seated correctly.
- Replace the Cover: Put the string head cover back in place, making sure it’s securely fastened.
5. Adjust the String Length:
- Bump the Head: Tap the string head against the ground several times to feed out the string.
- Trim the String: Cut the string to the desired length, using scissors or a knife.
6. Test the Mower: Start your mower and carefully test the string. If the string doesn’t feed properly or breaks easily, you may need to check for other issues like a clogged head or damaged string head mechanism.
Special Considerations for Automatic Feed Heads
Automatic feed heads require slightly different steps for string replacement. Here’s a general overview:
- Locate the Access Panel: Most automatic feed heads have a release button or a small access panel that opens to reveal the string spool.
- Remove the Old String: Pull out the remaining string and discard it.
- Insert the New String: Carefully insert the new string into the designated slot or guide. Refer to your user manual for specific instructions.
- Replace the Cover: Secure the access panel or cover back in place.
Note: Some automatic feed heads might require you to cut the string to a specific length before replacing it. Refer to the user manual for your specific model.
Maintenance Tips for Your String Trimmer
Replacing the string is a basic maintenance task, but regular care can prolong the life of your string trimmer and ensure it runs smoothly. Here are a few tips:
- Inspect the String Head: Check the string head for wear and tear regularly. Replace any damaged components promptly.
- Keep the Head Clean: Dirt and debris can clog the string head, hindering its performance. Clean it periodically with a brush or a damp cloth.
- Use the Right String: Use string that’s recommended for your specific lawn mower model. Using incompatible string can cause problems with the string feed mechanism.
- Store Properly: Store your lawn mower in a dry place, free from dust and debris, to prevent rust and corrosion.
