Maintenance Tips
Maintaining your Husqvarna lawn mower blade ensures the best performance. Regular maintenance prevents wear and tear, prolongs the lifespan of your mower, and keeps your lawn looking its best.
Regular Inspections
Inspect your mower blade at least once a month during the mowing season. Look for:

- Nicks or Damage: Check for any chips or cracks.
- Rust: Rust can corrode the blade, leading to potential breakage.
Cleaning the Blade
After every mowing session, clean the underside of the mower deck and the blade. Grass clippings can trap moisture, leading to rust. Use a shop towel or a brush to remove debris.

Lubricating Moving Parts
Apply grease to the pivot points and wheels of your mower every few months. This ensures smooth operation and reduces wear. Check your owner’s manual for specific lubrication points.
Seasonal Maintenance
Before winter storage, perform a thorough maintenance check:
- Drain Fuel: Empty the tank to prevent stale fuel issues.
- Replace Oil: Change the oil for a fresh start in the spring.
- Store Properly: Keep your mower in a dry place to avoid moisture damage.
Following Manufacturer Guidelines
Always refer to your Husqvarna owner’s manual for specific recommendations regarding maintenance and blade care. The manual provides vital information tailored to your mower model.
