摘要： PROBLEM TO BE SOLVED: To provide a turning control apparatus for a working vehicle enabling small turning with a small turning radius without a widened range of moving operation and specifically gentle turning with fine adjustment and eliminating disadvantages such as shocks to a car body caused by abrupt change in a running state of a running device.
SOLUTION: A pair of continuous variable transmissions 11R,11L to vary running speed of left and right running devices individually and continuously are respectively speed variably mounted in the turning control apparatus. The relation between a moving amount of a turning lever 26 from a straight-forward command position and a turning radius is determined in correspondence to a quadratic function to enlarge the turning radius as the moving amount widens and to change to the larger side a variation amount of the turning radius per a unit amount of the moving amount over a whole range. An operation mechanism 30 for running is actuated to attain a target turning radius obtained based on an operational position of the turning lever 26 and the relation with the secondary function.
