Why Belt Size Matters
Using the wrong belt size can cause numerous issues:
- Slipping or poor traction
- Uneven cutting
- Damage to pulleys and other components
- Reduced mower lifespan
That’s why it’s crucial to refer to the correct belt length, width, and type when replacing it.
Tips for Replacing Your Belt
- Inspect pulleys and tensioners: Replace worn or damaged parts to extend the life of your new belt.
- Use OEM belts when possible: Original belts are designed to fit perfectly and last longer.
- Double-check routing: Incorrect belt routing can cause performance issues or belt breakage.
- Keep the deck clean: A clean deck reduces friction and helps belts perform better.
