Why it works
The curved profile adds extra cutting edge, allowing the blade to shred grass into fine particles that fall back onto the turf as natural fertilizer. Its built‑in collection slots help prevent clogs when you mow frequently (every 3‑4 days is ideal).
Fitment
Designed for a wide range of Mountfield models including Empress 51Li, HP425, HW511PD, SP51H, SP53 series and the SP533 family (part numbers 295546048/BQ, 295546548/BQ, etc.). Check your mower’s model number to confirm compatibility.
Installation tip
Replace the old blade with the new one while the mower is off and the spindle is cool. Tighten the bolts evenly to maintain balance and ensure a smooth cut.
Upgrade your Mountfield mower with this authentic metal blade and enjoy a cleaner, healthier lawn every time you push the handle.
