Changing Blades on a Hustler FasTrak

This step-by-step walkthrough applies to all modern Hustler FasTrak models, including 48”, 54”, and 60” decks.

Signs Your Hustler FasTrak Needs New Blades

  • Tearing grass instead of cutting it cleanly
  • Visible dents, chips, or cracks
  • Vibration while mowing
  • Uneven cut patterns
  • Blades show thinning from wear

If you notice any of these symptoms, it’s time to install new blades before they cause additional wear to the spindle, deck, or engine.

Tools You’ll Need

  • 15/16" or 1-1/8" socket (depends on model)
  • Work gloves
  • Safety glasses
  • Blade removal tool or a block of wood
  • Replacement OEM Hustler FasTrak blades

Safety First
