1924年首次用联合收割机收获大豆。自从1925年最初试验情况发表后,开始注意了收获大豆时的损失,并发现用联合收割机收获大豆平均损失为总产量的9%左右。大豆收获直到目前损失减少很小。主要由于往复式切割器的振动,使割台损失约占联合收割机损失的85%,而且也限制了联合收割机收获大豆的生产效率。浮动式切割器比标准型切割器显著地减少了割台损失。这种型式的切割器早在 The first harvest of soybeans with a combine harvester in 1924. Since the publication of the initial test in 1925, attention has been paid to the loss of soybeans and the average loss of soybeans harvested with combine harvesters has been found to be about 9% of the total output. The loss of soybeans until now is minimal. Mainly due to the reciprocating cutter vibration, the header losses about 85% loss of combine harvester, but also limits the combine harvester harvesting soybean production efficiency. Floating cutters significantly reduce header losses compared to standard cutters. This type of cutter back in time
