Why does my Ferris F800X Lawn Mower have excessive mower vibration?
- RromerotonySep 8, 2025
If your Ferris Lawn Mower has excessive mower vibration, it could be that the blade mounting bolts are loose, so tighten them to 70 ft.lbs (94 Nm). The mower blades, arbors, or pulleys might be bent, so check and replace as necessary. The mower blades could be out of balance, so remove, sharpen, and balance them. Also, ensure the belt is installed correctly, and reinstall if needed.
