Sickle safety guard apparatus comprising an elongated rib laterally bifurcating into a pair of spaced apart longitudinally and laterally extending side wall portions respectively transitioning into a pair of distal, longitudinally and laterally extending, sides wall portions forming a longitudinally and laterally inwardly extending receiving gap between the side wall portions that decreases in separation laterally inwardly for forming respective guiding surfaces laterally inwardly followed by respective pressure surfaces of the side wall portions defining a longitudinally and laterally extending slot therebetween and the respective pressure surfaces radially inwardly increasing in separation to interior terminating ends wherein sickle teeth are received and guided by the guiding surfaces into said longitudinally and laterally extending slot and into abutment with the pressure surfaces while biasing apart the pair of biasing/pressure surfaces for providing a pressure fit between the biasing/pressure surfaces and the sickle teeth.
