A Quick Overview of Restringing a Briggs & Stratton Lawn Mower

Restringing a Briggs & Stratton lawnmower is a relatively straightforward task that can be accomplished with basic tools and some patience. The process involves removing the old string, installing the new string into the mower’s spool, and then adjusting the string length for optimal cutting performance. While the specific steps may vary slightly depending on your mower model, the core principles remain the same.

Tools You’ll Need

Before diving into the restringing process, make sure you have the necessary tools readily available.

Essential Tools:

  • Phillips-head screwdriver: This is essential for removing screws that secure the cutting deck.
  • Wire cutters or pliers: These will help you cut the string to the correct length.
  • New trimmer line: Choose the right type and thickness for your mower.
  • Gloves: Protect your hands from sharp edges and potential cuts.
  • Safety glasses: Always wear eye protection when working with power tools.
  • Optional: A small wrench: This might be needed to adjust the string tension depending on your mower model.

Choosing the Right Trimmer Line

The type of trimmer line you choose can significantly impact your mowing experience. Consider these factors:

  • Line thickness: Thicker lines provide more power for tougher jobs, while thinner lines offer better maneuverability for delicate areas.
  • Line material: Nylon lines are common and affordable, while braided lines offer durability and longer lifespan.
  • Line shape: Round lines provide a smooth cut, while square or star-shaped lines offer better cutting power.

Steps to Restring a Briggs & Stratton Lawn Mower

Disclaimer: The following steps are general guidelines and may vary slightly depending on your specific mower model. Always refer to your user manual for the most accurate instructions for your particular Briggs & Stratton lawnmower.

1. Disconnect the Spark Plug:

  • Locate the spark plug on the engine, typically on top or near the side.
  • Remove the spark plug wire by pulling it straight off the plug.
  • This prevents the engine from accidentally starting during the restringing process.

2. Remove the Cutting Deck:

  • Locate the screws that secure the cutting deck to the mower frame.
  • Use a Phillips-head screwdriver to remove these screws.
  • Carefully lift the cutting deck off the frame, ensuring that you don’t pull any wires or hoses.

3. Remove the Old Trimmer Line:

  • Locate the spool housing on the cutting deck.
  • There will likely be a small access door or cover to the spool. Remove this door.
  • You may need to use your wire cutters or pliers to remove the old string from the spool.

4. Install the New Trimmer Line:

  • Measure the new trimmer line according to the instructions in your user manual or the specifications on the spool.
  • Feed the new trimmer line into the spool, ensuring it is wound neatly and securely.
  • Some spool designs have a winding key or knob that helps you wind the line.
  • Once the line is fully wound, secure it by fastening the spool housing door or cover.

5. Adjust the String Length:

  • Most Briggs & Stratton mowers have a string length adjustment mechanism. This may be a screw, lever, or button.
  • Refer to your user manual for specific instructions on how to adjust the string length on your model.
  • Generally, you should adjust the string to the length recommended for your mower.

6. Reinstall the Cutting Deck:

  • Carefully align the cutting deck back onto the mower frame.
  • Reinstall the screws that hold the cutting deck in place, making sure they are securely tightened.

7. Reconnect the Spark Plug Wire:

  • Connect the spark plug wire back onto the spark plug. Ensure it is securely connected.

8. Test the Lawn Mower:

  • Start your lawnmower and test the string cutting performance.
  • If the string is not cutting properly, you may need to adjust the string length or make sure the spool is properly installed.

Tips for Restringing Your Briggs & Stratton Lawn Mower

  • Refer to your user manual: It is always best to consult your user manual for specific instructions tailored to your Briggs & Stratton lawnmower model.
  • Keep the line spooled evenly: This ensures smooth and consistent cutting.
  • Avoid over-tightening the string: Too much tension can damage the spool or make it difficult to feed string.
  • Test the cutting performance frequently: Adjust the string length as needed to ensure optimal performance.
  • Clean the spool housing regularly: Remove any debris or grass clippings that may hinder the string’s movement.

Troubleshooting Common Problems

  • String keeps breaking: This could be due to using the wrong type of string, a worn-out spool, or a blockage in the cutting head.
  • String doesn’t feed out properly: This could be due to a jammed spool, a broken string tensioner, or improper string winding.
  • Mower vibrates excessively: This could be caused by an unbalanced spool or an improperly installed cutting deck.
