ABSTRACT:
The invention relates to a lawn mower knife assembly including a rigid bar, plate or disc attached to a motor-driven generally vertical shaft and provided, at a distance from the shaft attachment, with at least two attachment points for knife means, and at least two knife means, each including a blade section provided with a cutting edge and a shank section adapted for the fixation of the knife means to the bar, plate or sheet.
The new feature is that each of the attachment points comprises a flat surface section in which there is made a through-hole for a screw or the like and a recess arranged beyond the hole, and that the shank section of each knife means includes a flat surface section with a through-hole and a projection provided adjacent said surface section and extending away from the plane of the surface section, while the surface sections of the attachment points and the shank section are adapted, when in mounted condition, to lie in contact with each other with the holes aligned, and the projection is adapted for accommodation in the recess in order to constitute a rotary latch which is yieldable to pre-determined strain.
