Pneumatic finger attachment for header unit

A harvesting system for agricultural machines comprising:

• a crop cutting means disposed transversely of the direction of travel of the harvesting marchine;
• a crop combing means disposed adjacent to and extending forwardly of said cutting means;
• said combing means having a plurality of receiving platforms collectively defining a generally planar surface beginning at a point forwardly of said cutting means and extending forward of said cutting means and defining a narrow gap thereby for receiving the crop to be cut, and pneumatic means for generating a bed of air moving along the upper surface of said combing means in a direction toward said cutting means and substantially parallel to the cutting plane of said cutting means, said pneumatic means including nozzle means for discharging air in a direction substantially along said upper surface of said combing means to create said bed and delivery means for delivering air under pressure to said nozzle means, said nozzle means being located in the plane of said bed of air and said delivery means being disposed generally beneath said combing means, said nozzle means comprising an outlet nozzle disposed on the upper face of at least some of said receiving platforms to receive the forced air supply and arranged to direct a forced air flow towards the cutting means, substantially parallel to said planar surface to augment the gathering of said crop.
