る歩行型移動農機のハンドル向き調節装置。 The operating handle 4 is rotatably attached to a handle mount 6 attached to the upper part of the mission case 2, and three or more lock holes 6a are provided between the flange 9A provided at the base of the handle and the handle mount 6. ... and a lock pin 11 that is selectively engaged with the pin lock mechanism A. By selective engagement of the lock pin 11, the control handle 4 can be moved to a neutral attitude toward the rear of the aircraft body, or to swing left and right. This is a handle orientation adjustment device for a walking-type mobile agricultural machine that is configured to be able to switch between a vertical position and a vertical position, and two auxiliary lock holes 13a are provided at locations on the flange 9A and the handle mounting base 6 that are different from the location where the pin lock mechanism A is installed. , 13b, and an auxiliary lock pin 14 that is selectively engaged with the auxiliary pin lock mechanism B. When the pin lock mechanism A is in the locked state of the handle neutral position, the auxiliary pin lock mechanism B 14 is located in the center of both auxiliary lock holes 13a, 13b and is in a state where it cannot be inserted, and both auxiliary lock holes 13a, 1
3b is set to be smaller than the distance between the neutral lock hole 6b and the adjacent lock hole 6a or 6c in the pin lock mechanism A.
