A combine in which a pair of front and rear swing arms is supported by a machine body frame via a bearing member, one end of each of the swing arms is supported at the front and rear of a track frame of a traveling device, and the track frame can be lifted and lowered relative to the machine body frame (2) by rotation of the swing arms. A swing arm (45) is constructed from an upper arm (46), a lower arm (47), and a support shaft (48) for connecting the upper arm and the lower arm, and the swing arm is supported at the bearing member, by an outer end or an inner end of the support shaft, the upper arm, and the lower arm. Also, left and right longitudinal frames (2A, 2A) extending in the front-rear direction of the machine body frame are placed at the center, on the left and right of the machine body frame, and intermediate sections in the front-rear direction of the left and right longitudinal frames are connected by a connection member (80) that is upwardly bent in arc. The distance in the left and right direction between the swing arms provided at the left and right traveling devices is increased, which secures a large space below the machine body frame so that mad and earth can be easily pass through during traveling. |
