Ryobi String Trimmer Auto Feed Not Working Solved? Latest {In-2023}

Are you frustrated because your Ryobi string trimmer’s auto-feed feature is not working properly? If you’re tired of manually feeding the line or dealing with frequent line breakages, don’t worry! In this article, we will explore the possible causes behind the auto-feed issue and provide you with some practical solutions to get your trimmer back in working order.


Ryobi is a renowned brand that offers a wide range of garden tools, including string trimmers. These trimmers come equipped with an auto-feed feature, which automatically advances the line as it wears down, ensuring uninterrupted trimming. However, there are instances where the auto-feed feature may not function as expected, causing inconvenience to users. Let’s delve into the common causes and solutions for this problem.

Understanding the auto-feed feature of Ryobi string trimmers

Before we dive into troubleshooting, it’s essential to understand how the auto-feed feature works. Ryobi string trimmers typically utilize a spool of nylon trimmer line. As the line wears down during use, the auto-feed mechanism kicks in, releasing more line to maintain the optimal cutting length. This mechanism helps save time and effort by eliminating the need to manually adjust or replace the line frequently.

Common causes for auto-feed not working

There can be several reasons why your Ryobi string trimmer’s auto-feed feature is not functioning properly. Let’s explore some of the common causes and their solutions.

Insufficient line length

One of the primary reasons for auto-feed failure is insufficient line length. If the line is too short, it may not engage with the auto-feed mechanism, leading to feed problems. To ensure proper functioning, make sure the trimmer line extends beyond the trimmer head by at least 3 to 6 inches.

Line blockages or tangles

Another common issue that can hinder the auto-feed function is line blockages or tangles. Debris, grass clippings, or tangled line can prevent the smooth operation of the auto-feed mechanism. Regularly clean the trimmer head and remove any obstructions or tangled line to maintain optimal performance.

Damaged or worn-out spool

A damaged or worn-out spool can also cause the auto-feed to malfunction. Over time, the spool may become cracked, warped, or damaged, affecting its ability to release the line properly. If you notice any signs of damage or wear, it’s recommended to replace the spool with a new one specifically designed for your Ryobi trimmer model.

Troubleshooting steps to fix the auto-feed issue

Ryobi String Trimmer Auto Feed Not Working Solved

If you’re experiencing problems with the auto-feed feature of your Ryobi string trimmer, try following these troubleshooting steps to resolve the issue.

Step 1: Check the line length

Start by ensuring that the trimmer line is of sufficient length. If it’s too short, unwind additional line from the spool until it extends beyond the trimmer head by at least 3 to 6 inches.

Step 2: Clean the trimmer head

Remove any debris, grass clippings, or tangled line from the trimmer head. Use a soft brush or compressed air to clean the area thoroughly. This step helps eliminate any blockages that might be hindering the auto-feed mechanism.

In Step 3: Inspect the spool

Carefully examine the spool for any signs of damage or wear. If the spool is cracked, warped, or damaged, it’s advisable to replace it with a compatible replacement part. Refer to the user manual or contact Ryobi customer support for guidance on obtaining the correct spool for your trimmer model.

Step 4: Adjust the line tension

Improper line tension can affect the auto-feed performance. Make sure the trimmer line is correctly wound and properly tensioned. Follow the user manual instructions to adjust the line tension if necessary.

Step 5: Replace the spool or trimmer head

If all else fails, and the auto-feed issue persists, consider replacing the spool or even the entire trimmer head. Sometimes, internal components within the trimmer head may become damaged or worn out, causing the auto-feed to malfunction. By replacing these parts, you can restore the auto-feed feature to its optimal functionality.

Additional tips for optimal auto-feed performance

To ensure optimal performance and longevity of your Ryobi string trimmer’s auto-feed feature, consider the following tips:

  • Using the correct line diameter: Always use the recommended line diameter specified for your trimmer model. Using the wrong line diameter can negatively impact the auto-feed function.
  • Proper winding of the spool: When winding the trimmer line onto the spool, make sure to follow the correct pattern as mentioned in the user manual. Improperly wound line can cause feed issues and hinder the auto-feed mechanism.
  • Avoiding excessive force or speed: While using the trimmer, avoid excessive force or high speed, as this can cause the line to break frequently. Maintaining a steady and controlled cutting motion will help prevent line breakages and ensure smoother auto-feed operation.
