The purpose of the present invention is to provide a combine harvester with which manufacturing costs such as sheet metalworking of support legs 71a, 71b can be reduced, and the support legs 71a, 71b can be made more lightweight. This combine harvester is provided with left and right support legs 71a, 71b each having a widening shape in which the left-right width dimension at the lower end increases as seen in the front-rear direction of a traveling machine body 1, and left and right auxiliary support legs 72a, 72b extending along the machine-outside surfaces of the support legs 71a, 71b. Left and right track frames 50 are linked below the left and right sides of the traveling machine body 1 via the left and right support legs 71a, 71b and auxiliary support legs 72a, 72b, and left and right travel parts 2 are supported on the left and right track frames 50. Support leg brackets 75 are disposed on the upper-surface sides of the track frames 50, and the lower-end sides of the support legs 71a, 71b are integrally fastened to the side surfaces of the track frames 50 and the side surfaces of the support leg brackets 75. The lower-end sides of the auxiliary support legs 72a, 72b are integrally surface-pressure-bonded to the flat upper surfaces of the support leg brackets 75.La présente invention concerne une moissonneuse-batteuse grâce à laquelle les coûts de fabrication, par exemple, du travail de la tôle des pieds de support (71a, 71b) peuvent être réduits, et les pieds de support (71a, 71b) peuvent être rendus plus légers. Cette moissonneuse-batteuse est dotée de pieds de support gauche et droit (71a, 71b) ayant chacun une forme évasée dans laquelle la dimension de la largeur gauche-droite au niveau de l'extrémité inférieure augmente selon une vue dans la direction avant-arrière d'un corps de machine mobile (1), et les pieds de support auxiliaires gauche et droit (72a, 72b) se prolongeant le long des surfaces extérieures de la machine des pieds de support (71a, 71b).
