The invention addresses the problem of providing a combine which is configured so that mechanical vibration of a forward-reverse rotation switching case (121) and a forward-reverse rotation operating device (132) is reduced and so that the connection structure between the forward-reverse rotation switching case (121) and the forward-reverse rotation operating device (132) is simplified. The combine is provided with a harvesting device (3), a threshing device (9), and a moving machine body (1) which is provided with a moving section (2) and an engine (7), and the combine is configured so that stalks of grain are supplied from the harvesting device (3) to the threshing device (9). The combine is also provided with: the forward-reverse rotation switching case (121) which inputs the rotational driving force of the engine (7) into the harvesting device (3) and the forward-reverse rotation operating device (132). The forward-reverse rotation switching case (121) is disposed on one of left and right harvesting device supports (231) by which the harvesting device (3) is supported, and the forward-reverse rotation operating device (132) is disposed on the other of the left and right harvesting device supports (231).Linvention vise à procurer une moissonneuse-batteuse qui est configurée de telle sorte quune vibration mécanique dune enceinte de commutation de rotation avant-arrière (121) et dun dispositif dactionnement de rotation avant-arrière (132) est réduite, et de telle sorte que la structure de liaison entre lenceinte de commutation de rotation avant-arrière (121) et le dispositif dactionnement de rotation avant-arrière (132) est simplifiée. A cet effet, linvention porte sur une moissonneuse-batteuse, qui comporte un dispositif de moissonnage (3), un dispositif de battage (9) et un corps de machine en déplacement (1) qui comporte une section de déplacement (2) et un moteur (7), et laquelle moissonneuse-batteuse est configurée de telle sorte que des tiges de graine sont a
