A stepped, high-flute blade like this is Masport's own design for the Quickcut range, built to lift clippings into the catcher rather than just spin flat.
This is a direct-fit blade and bolt for the 515mm Quickcut deck, at 135mm long and 44mm wide with a 13mm hole. One blade, one bolt, steel construction, fitted with a spanner in a few minutes.
Once the flute wears down or the edge rounds off, clippings stop lifting properly and start matting into the lawn instead of catching. A fresh blade brings the lift and the cut back in one swap, and costs less than a trip through a dealer for the branded part.
Fitment and full specs are in the tabs below.
