TURN CONTROLLER FOR WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To facilitate a turn operation for turning a work vehicle at a small angle while allowing a turn operation for turning the work vehicle at a large angle. SOLUTION: When a turning command is issued by a main turning command means and while this turning command is effective, transmission of power to a running gear of a turning inner side is interrupted and power is transmitted to a running gear of a turning outer side to continuously operate the work vehicle into a turning state for turning. When a turning command is issued by a sub turning command means and while this turning command is effective, turn driving is controlled in an intermittent operation form repeating an operation in the turning state during a set operation time Ton and then an operation in a linearly driving state where the work vehicle is linearly moved by transmitting power to both running gears during a set pause time Toff.
