<P>PROBLEM TO BE SOLVED: To increase recovery efficiency of grain by bringing the grain in a substance to be treated on a swinging separation shelf to be not discharged outward of a machine together with straw dust, e.g., when turning the machine after finishing reaping of one side of a farm field. <P>SOLUTION: There is installed a control unit (CU) which automatically cuts off a first clutch (4h) for driving a reaping device (4) when a non-reaping operation height is detected by a height detection means (4l) and automatically cuts off a second clutch (20m) for driving a feed chain (13B) and the swinging separation shelf (20) in addition to the cutting off of the first clutch (4h) when the non-reaping operation height is detected by the height detection means (4l) and a layer thickness thinner than a predetermined layer thickness is detected by a layer thickness detection means (96). <P>COPYRIGHT: (C)2012,JPO&INPIT |
