ABSTRACT:
A guard for a sickle of an agricultural plant cutting machine includes a forwardly extending finger including a longitudinally extending, upwardly facing surface extending over the sickle, which includes a rearwardly facing air discharge nozzle therein located above and/or forwardly of the sickle, and the finger includes an air flow passage extending internally therethrough from an air inlet adjacent to a base of the finger to the nozzle, for delivering a flow of pressurized air thereto, the nozzle being at least mostly flush with or recessed into the upwardly facing surface. As a result, the nozzle is operable for discharging the flow of air rearwardly over the finger without obstructing plant material flow thereover, the air flow being sufficient to blow at least a substantial amount of loose grain and other plant material located forwardly of the front edge of a header floor of the machine, onto the floor for collection by a conveyor of the header for processing.
