Joint research conducted by the National Soybean Research Center of Embrapa, Brazil, and the department of Biological Systems Engineering of University of Nebraska, Lincoln, was aimed at the design and development of new thresher/harvester concept for soybeans and other grain crops. The research, wich also was supported by ROTA industry of farm Machinery, from Brazil, resulted in an experimental prototype for threshing/harvesting soybeans and rice from standing, uncut plants. It used impact energy provided by nylon cords, fixed in a spiral path on opposite rotating shafts, striking the soybeans and the rice seeds from both sides of the plant row in upward direction. The device threshed 95.4% of the soybeans at average ground speed of 6.6km/h, being statiscally lower than 99% threshed at 3km/h. On the other hand, 25.8% of the material other than grain (MOG), removed at 6.6km/h, also was significantly less than the 32.1% of MOG remove at 3km/h. The 76.3% seed vigor value obtained at 6.6km/h was not significantly different from the 78.5% vigor of the hand threshed, but was significantly higher than the 67.1%, and 63.5% seed vigor values obtained when threshed by the device at 3km/h, and by a conventional combine, respectively. Tetrazolium and hypochlorite tests indicated that the numbers of mechanically damaged seeds caused by hand threshing and by the device working at the observed ground speeds, were not significantly different. However, they were statistically lower than the mechanically damaged and broken seeds resulting from conventional combining. The estimated average energy/ha required by the threshing device was approximately 4 MJ/ha, or about one-eight of that required by the tangentially fed threshing cylinder and concave of conventional combines. Preliminary tests with dryland rice showed 99.1% threshing efficiency and 8.6% MOG removed at a ground speed of 3km/h.
