Abstract
A cutter assembly for mowing apparatus comprises a sickle guard having individual guards whose guard bodies are connected to a cutter bar via mounting pads. Each guard is provided with a rearward knife slot within which knife sections can move back and forth in a reciprocating manner. Hold-down members are provided to act against an upper face of the knife sections, the hold-down members being formed as ball plungers and are screwed into a front part of a hold-down arm. The hold-down arm at its rearward end is fixed by a base to the cutter bar by means of guard mounting screws.
