MOVING AGRICULTURAL MACHINE

摘要

PROBLEM TO BE SOLVED: To turn a machine body with the turning radius set substantially constant regardless of the vehicle speed when the operation amount of a steering handle is constant. SOLUTION: In this moving agricultural machine including a running speed change member 5 for steplessly changing the driving speed of right and left running crawlers 2 by operating a running speed change lever 73 and a steering member 28 for steplessly changing a difference in driving speed between the right and left running crawlers 2 by operating the steering handle 19, when the operation amount of the steering handle 19 is constant, the speed ratio (V1/V2) of the right and left running crawlers is kept substantially constant regardless of the vehicle speed.
