Abstract: A cutting assembly for a mowing machine has a disk (12) and a knife member assembly. The disk (12) has a surface portion (14) of which at least a peripheral portion is planar. At least three knife members (18), which have a cutting edge (50), a beveled surface portion (48) which extends from the cutting edge (50) and a body surface portion (60) which extends from the beveled surface (48), are mounted to the disk (12) at positions so that the knife members (18) are displaced substantially equidistantly one from another and so that upon rotation of the disk (12) in a plane about a central disk axis, the cutting edge (50) of the knife members (18) extends away from the disk (12), and the body surface (60) is. with respect to the disk planar surface, inclined at an angle.
