PURPOSE:To smoothly discharge cut materials backward by installing a transporting member to prevent retention of cut materials at a connection part (vicinity) of a supporting member of liftably coupling and holding a second reaping blade device and the second reaping blade device. CONSTITUTION:Even if a supporting member 7 of liftably coupling and holding a second reaping blade device 4 exists at a position to resist flow of cut delivered materials by the second reaping blade device 4, the cut delivered materials are discharged backward by a transporting member 8 installed at a connection part (vicinity) of the supporting member 7 and the second reaping blade device 4 to prevent retention of the cut delivered materials.
