PROBLEM TO BE SOLVED: To improve efficiency of reaping work and manual threshing work.SOLUTION: A threshing feed chain 13 is driven by driving force transmitted from either a reaping side transmission part HV transmitting driving force from a reaping device 3 side to the threshing feed chain 13, or a threshing side transmission part DV transmitting driving force from a threshing device 4 side to the threshing feed chain 13. A manual threshing restriction member 42, which restricts supply of grain culms to be subjected to manual threshing, is installed at a conveyance start end of the threshing feed chain 13. When the manual threshing restriction member 42 is switched into a state allowing the supply the grain culms to be subjected to manual threshing to the threshing feed chain 13, blockage of driving force from the reaping side transmission part HV to the threshing feed chain 13 and connection of driving force from the threshing side transmission part DV to the threshing feed chain 13 are automatically executed. |
