A genuine Castel 51 cm (20 in) XC53 lawn‑mower blade is the perfect upgrade for anyone who wants a cleaner, healthier lawn. Made from hardened steel, this 3‑in‑1 mulching blade cuts, bags and recirculates grass in one smooth motion, leaving a fine mulch that feeds the soil and reduces the need for frequent fertilising.
Key specs
– Blade length: 51 cm (20 in)
– Width: 5.7 cm
– Centre hole Ø 18 mm, outer holes Ø 8 mm (75 mm apart)
Designed for Castel Garden models—including XC 53 BS, BSW, GSW and the full range of 2012‑2017 series—this replacement blade fits seamlessly into the mower deck. Its curved profile increases the cutting edge, allowing grass to be chopped multiple times before it falls back onto the turf as tiny particles. The result is a smoother finish and less clumping under the deck.
Why choose a mulching blade?
– Improves lawn health by returning nutrients to the soil
– Reduces bagging time and waste
– Ideal for lawns mowed every 3‑4 days
For overgrown areas, mow more often to prevent deck clogging. With this authentic Castel blade you’ll enjoy a sharper cut, efficient mulching and a lawn that looks professionally maintained—all at a price that fits your budget.
