ABSTRACT:
The harvesting system has a crop cutting device disposed transversely of the direction of travel of the harvesting machine. A crop combing device is disposed adjacent to and extends forwardly of the cutting device. There is provided a pneumatic arrangement for generating a bed of air moving across the combing device in the direction towards the cutting device and generally parallel to the cutting plane of the cutting device. The moving bed of air facilitates gathering of the crop and reduces grain loss. The pneumatic arrangement includes nozzles for discharging air whereby to create said bed and a delivery system for delivering air under pressure to the nozzles. The nozzles are located in the plane of the bed and the delivery system is disposed generally beneath the combing device. Also disclosed is a finger attachment for a known harvesting system of agricultural machines. The finger attachment facilitates conversion of the known harvesting system to a harvesting system according to the invention. A method of harvesting is also disclosed.
