A genuine Atco 46 cm rotary lawn‑mower blade is the perfect replacement for the 18S, 18SE and 18SH models. Made from hardened steel, this 3‑in‑1 mulching blade cuts, bags and finely mulches grass in one smooth pass, leaving a tidy, healthy lawn.
Key specifications
– Blade length: 46 cm (18 in)
– Blade width: 5.8 cm
– Centre hole Ø: 18 mm
– Outer holes Ø: 8 mm (74 mm apart)
Designed with extra curves and a longer cutting edge, the blade lifts grass into the deck where it is repeatedly chopped into tiny particles that fall back onto the turf as natural fertilizer. It works best on lawns mowed every three to four days; for thicker growth you may need to increase mowing frequency to avoid deck clogging.
Fitment
Compatible with Atco Liner 18S (299489027/AT5), Liner 18SE (299489527/AT2 & AT6) and Liner 18SH (299489037/AT5).
Upgrade your mower with this original Atco mulching blade for sharper cuts, smoother operation and a greener yard—without the hassle of buying a whole new mower.
