POSTURE-CONTROLLING DEVICE OF REAPING HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide a posture-controlling device so as to avoid the thrusting of a reaping part into a field caused by a pitching control performed in the case of traveling over a swollen part on transferring and traveling after finishing one working process to a next working process by repeating advancing and retreating in a reaping harvester equipped with a posture change-operating means capable of freely change-operating a front to rear inclining angle of a machine body against the ground-contacting part of a traveling unit, and a controlling means for performing the pitching control for controlling the functioning of the posture change-operating means so as to maintain the front to rear inclining angle-operating means based on a horizontal reference surface of the machine body at a set inclined angle based on information by the front to rear inclined angle-detecting means for detecting the front to rear angle based on the horizontal reference surface of the machine main body. SOLUTION: This posture-controlling device is constituted by setting more insensitive control sensitivity for performing a restricted pitching control for controlling the functioning of the posture change-operating means than that after traveling a set distance, during the time in which the machine body starts its advancing travel and travels the set distance.
