The casing 91 is formed by an inclined surface 91 </ b> A that covers the front side of the suction dust exhaust fan 90 and then tilts upward, and an upper surface 91 </ b> B that covers the upper side of the suction dust exhaust fan 90 and tilts horizontally or gently rearwardly downward.

(Exhaust treatment device)
On the rear side of the threshing device 3, a waste treatment device 95 that pivots a plurality of waste cutters 96 in the left-right direction is arranged. The waste conveyed rearward by the waste transporting device 50 is supplied to the waste processing device 95 from the terminal end of the waste transporting device 50. The waste cutter 96 includes a pair of upper rotary cutter blades 96A and a lower rotary cutter blade 96B, and the waste supplied from the waste transport device 50 passes between the pair of rotary cutter blades 96A and 96B. After being cut finely, it is discharged out of the machine.

  The outer sides of the pair of rotary cutter blades 96A and 96B are covered with a hood, and the front side of the upper rotary cutter blade 96A is a cutting for guiding the cut waste of the cut waste to fall backward. A gutter guide plate 97 is provided. The upper portion of the cutting guide plate 97 is provided at substantially the same height as the lower portion of the upper rotary cutter blade 96A, and the lower portion of the cutting guide plate 97 is provided below the lower portion of the lower rotary cutter blade 96B.
