Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your ACTIVLIFE Mower Deck Springs. These springs are designed as replacement parts for specific Weed Eater lawn mower models to ensure optimal deck function and cutting performance. Please read these instructions carefully before proceeding with installation or maintenance.
Product Overview
The ACTIVLIFE Mower Deck Springs are durable, black metal extension springs. They are crucial components for maintaining the correct tension and position of your mower deck, which directly impacts cutting height and consistency. This package includes three (3) springs.

This image displays three identical black metal extension springs, designed for use with mower decks. Each spring features a coiled body and hooks at both ends for secure attachment.
Setup and Installation
Proper installation of mower deck springs is vital for safe and effective operation. Always ensure the mower is turned off, the spark plug wire is disconnected, and the deck is lowered to a safe working position before beginning any installation.
- Safety First: Disconnect the spark plug wire to prevent accidental starting. Wear appropriate safety gear, including gloves and eye protection.
- Identify Old Springs: Locate the existing mower deck springs that need replacement. Note their attachment points and orientation.
- Remove Old Springs: Carefully detach the old springs. Tension can be high, so use appropriate tools (e.g., spring puller, pry bar) to avoid injury.
- Attach New Springs: Hook one end of the new ACTIVLIFE spring to its designated attachment point on the mower deck or frame.
- Secure Second End: Using a spring puller or similar tool, stretch the spring and attach the other hook to its corresponding anchor point. Ensure the spring is securely seated.
- Verify Installation: Double-check that all springs are correctly installed, securely attached, and free from kinks or damage.
Refer to your specific Weed Eater mower's owner's manual for detailed diagrams and instructions regarding spring placement for models S165H42A, WE14542L, WE16542D, and WE16542E.
Operating Considerations
Once installed, the mower deck springs work automatically to maintain deck tension. No specific 'operation' is required from the user beyond ensuring they are correctly installed and functioning.
- Deck Leveling: After replacing springs, it is recommended to check and adjust your mower deck's leveling according to your mower's owner's manual to ensure an even cut.
- Visual Inspection: Periodically inspect the springs for proper tension and attachment before each use.
Maintenance
Regular maintenance helps extend the life of your mower deck springs and ensures consistent mower performance.
- Cleanliness: Keep springs free from excessive dirt, grass clippings, and debris. A stiff brush can be used for cleaning.
- Inspection for Wear: Regularly inspect the springs for signs of wear, stretching, corrosion, or damage. Look for cracks, deformation, or weakened tension.
- Lubrication (Optional): A light coating of rust-inhibiting lubricant can be applied to the springs to prevent corrosion, especially if stored in damp conditions. Avoid over-lubricating, which can attract dirt.
- Replacement: Replace springs immediately if they show signs of significant wear, damage, or loss of tension, as this can affect deck stability and cutting quality.
Troubleshooting
If you encounter issues related to your mower deck springs, consider the following:
- Uneven Cut: If your mower is cutting unevenly, check if the springs are properly installed and if any are stretched or broken. Also, verify the deck is level.
- Deck Sagging: A sagging mower deck can indicate weakened or broken springs. Inspect all springs for proper tension and replace as needed.
- Spring Detachment: Ensure the hooks of the springs are fully seated in their attachment points. If a spring repeatedly detaches, inspect the attachment points for wear or damage.
