A cylinder cutting blade for a lawn mower that includes at least two modular cylinder cutting blade sections. Each modular cylinder cutting blade section effectively being a short cylinder cutting blade which are rotationally connected together in succession in such a manner that rotation of one modular cylinder cutting blade section results in rotation of the other modular cylinder cutting blade sections. Each modular cylinder cutting blade section includes a longitudinal axis, a plurality of cutting bars which spiral around the longitudinal axis, a frame to hold the cutting bars in their respective positions, and a locking mechanism. The locking mechanism of each modular cylinder cutting blade section interacts with the locking mechanism of adjacent modular cylinder cutting blade sections to rotatably lock the modular cylinder cutting blade section to the adjacent modular cylinder cutting blade sections.
