Diagnosis: The bag frame is damaged or not aligned with the rear cover hooks.
Fix:
- Inspect the bag frame (part number 3705442002) for bends or cracks.
- Check the rear cover (part number 3126689003). Ensure the mounting hooks are intact.
- Verify the grass catcher (part number 3800109002) is seated fully into the frame.
If that didn't work:
- The torsion spring (part number 3660559001) that provides tension may be broken.
- The trail shield (part number 3129771001) or bevel supports (part number 3129770001) may be misaligned, preventing proper bag placement.
Heads up: Empty the bag before it's completely full. Overloading strains the frame and attachment points.
