Abstract:
A vegetation cutting tool including at least one demountable blade which adopts a substantially radial orientation under centrifugal force, the demountable blade being mounted via a post and slot, the post having an enlarged head and being adapted to traverse the slot between an operative position whereat the blade may rotate, and a dismount position whereat the enlarged head of the post is aligned with an enlarged portion of the slot such that the blade can be dismounted;wherein an abutment is provided adjacent the post; wherein, when the blade is in the operative position, the blade must be rotated to a substantially non-radial orientation prior to translation to the dismount position; wherein the blade is mounted to a link which is, in turn, pivotably mounted to a hub such that the link and blade tend to be substantially co-linear and radial under centrifugal force; and wherein the link must be substantially radial and the blade must be substantially nonradial before the blade can be dismounted from the link.
