PROBLEM TO BE SOLVED: To quickly perform a turn and improve the turning performance by providing such a structure as to be capable of freely selecting the control for interlocking each mechanism and the control for independently actuating it. SOLUTION: In this movable agricultural machine, a driving force is transmitted to lateral traveling crawlers through a speed change member capable of continuously varying the traveling speed by the operation of a main gear shift lever that is a traveling speed change lever, and a steering member is operated by a steering wheel to continuously vary the difference in driving speed between the lateral traveling crawlers. In this agricultural machine, the speed change member is connected to the main gear shift lever through a deceleration output shaft 178 that is a cooperating route for reducing the vehicle speed in proportion to the operation quantity of the steering wheel, or the speed change member is connected to the main gear shift lever through a direct drive output shaft 179 that is a third route different from the deceleration output shaft 178, whereby the deceleration output shaft 178 and the direct drive output shaft 179 are properly used. Further, this agricultural machine is constituted so that the control for interlocking the steering mechanism to the transmission mechanism and the control for independently operating each mechanism are selectable. |
