MOVING AGRICULTURAL MACHINE

摘要

PROBLEM TO BE SOLVED: To simplify assembling and adjusting works and parts controls, improve handling workability and diversify traveling transmission and steering performance. SOLUTION: In a moving agricultural machine provided with a first hydraulic pump 23 and a first hydraulic motor 24 for driving left and right traveling crawlers and a second hydraulic pump 26 and a second hydraulic motor 27 generating a difference in driving speed of the left and right traveling crawlers, the machine is provided with a steering actuator 74 detecting manipulated variable of a steering wheel 19 and performing an output control of a second hydraulic pump 26 and the machine is constituted so as to detect neutral of sub-transmission and discontinue a steering operation by the second hydraulic pump 26 and the second hydraulic motor 27.
