Cylinder blade for a mower

A lawn mower comprising:

• a motor;
• and
• a cylinder cutting blade engageable by the motor, wherein the cylinder cutting blade comprises at least two modular cylinder cutting blade sections, each modular cylinder cutting blade section comprising:
• 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;
• wherein the modular cylinder cutting blade sections are mounted in succession so that their axes are substantially co-axial and the locking mechanism of each said modular cylinder cutting blade section interacts with the locking mechanism of it's adjacent said modular cylinder cutting blade section so that rotation of one of the modular cylinder cutting blade sections results in rotation of the other modular cylinder cutting blade section.

A modular cutting blade apparatus comprising:

• a first modular cylinder cutting blade section having:
• opposing ends;
• a longitudinal axis;
• a plurality of cutting bars which spiral around the longitudinal axis;
• and
• a frame which locates the cutting bars in their respective positions;
• wherein the frame of the first modular cylinder cutting blade section comprises a locking mechanism adapted to interact with a locking mechanism of a second modular cylinder cutting blade section so that, when the second modular cylinder cutting blade section is mounted adjacent to the first modular cylinder cutting blade section with the longitudinal axes substantially co-axial, the locking mechanism of the first modular cylinder cutting blade section interacts with the locking mechanism of the second modular cylinder cutting blade section to rotatably lock the first modular cylinder cutting blade section to the second modular cylinder cutting blade section so that rotation of the first modular cylinder cutting blade section results in the rotation of the second modular cylinder cutting blade section.
