A mechanism for removing dirt and debris from the interior of a divider member mounted on the end disc of a disc cutterbar used in a disc mower-conditioner is disclosed wherein the dividers are provided with air inlet openings to permit the introduction of air into the interior chamber of the hat-shaped divider members. Each divider member is provided with a plurality of fan blades mounted to the top plate thereof to exhaust air from within the interior chamber and create a flow of air from the air inlet openings through the interior chamber and exciting a discharge opening formed between the divider top plate and a stationary cover mounted thereabove. This flow of air cleans the interior chamber of dirt and debris. An optional filter can be utilized to reduce the amount of dirt and debris permitted to enter the interior chamber through the air inlet openings.
In a disc cutterbar for severing standing crop from the ground and having a transmission casing housing power transmission means for transferring rotational power to a plurality of disc cutter assemblies from a source of rotational power, each said disc cutter assembly having at least one knife mounted thereon for engaging and severing standing crop material upon rotation thereof, said disc cutter assemblies including a pair of end discs, each of which having a generally hollow hat-shaped divider mounted thereon for rotation therewith to facilitate the flow of crop material across the disc cutterbar, each said divider having an outer wall defining an interior chamber therewithin, an improved divider comprising:
In a disc mower-conditioner having a mobile frame adapted for movement over a field, a disc cutterbar supported by said frame at a forward extremity thereof adjacent the ground to sever standing crop material therefrom, said disc cutterbar including end discs having a hollow hat-shaped divider rotatably mounted thereon, said divider including a generally vertical outer wall defining an interior chamber therewithin;
