SWING CONTROL DEVICE OF WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a swing control device of a working vehicle capable of performing swing operation by a proper swing force such that an operator does not feel the excess and deficiency of the swing force when the swing operation is performed. SOLUTION: This swing control device of a working vehicle comprises a swing directive means 26 formed so that the swing force can be changed by differentiating the traveling speeds of a pair of traveling devices 1R and 1L in a swing state and directing a swing state providing a larger swing force as the amount of movement to a position apart from a straight forward movement directive position is larger and a manually operated swing force change and set means 42 capable of changing and setting a correlation between an operating position and a target swing force in a state where the swing force when the device is operated to the maximum operating position is increased and decreased. Based on the directive information from the swing directive means 26 and the set information from the swing force change and set means 42, the traveling speeds of the pair of traveling device 1R and 1L are differentiated so that the target swing force can be provided for swinging.
