ABSTRACT:
A machine for cutting grass and the like having a flexible strip-like cutting member supported by a disc within a housing. The strip-like member is mounted vertically and the housing has a slope such that the strip-like member is rotated to have a horizontal leading cutting edge extending beyond the housing and an inclined trailing edge which creates a vortex effect within the housing when the strip is driven by a motor to cause grass to assume a more vertical position for cutting thereof. If the cutting edge of the strip strikes an obstacle, it will be deflected into a recess in the housing rather than propelling the obstacle which might have resulted if the blade were rigid. A bottom cover plate is removably secured to the housing to permit the disc carrying the cutting member to store the same therein. Indexing of the cutting member permits measured amounts thereof to be fed from storage.
