<P>PROBLEM TO BE SOLVED: To make automatic control on work behaviors after turning executed accurately while preventing slip of wheels on the turning inside during turning travel in a riding working machine with a turning interlocking automatic control device for making a prescribed behavior performed automatically after turning. Ž<P>SOLUTION: Four wheels of front wheels and rear wheels supporting a riding machine body are supported by a front wheel suspension mechanism and a rear wheel suspension mechanism 3S capable of adjusting elastic supporting force. and a transmission shaft rotation number sensor detecting the number of rotation of the inside axle during turning is arranged in the right and the left of the front or the rear wheels. Moreover, a control device controlling the elastic supporting force of the front wheel suspension mechanism and the rear wheel suspension mechanism 3S is arranged. When a turning angle calculated from the detected rotation number of the transmission shaft rotation number sensor exceeds a prescribed angle, travel stabilizing control of the riding working machine is performed by the control device executing control so that the elastic supporting force on the turning inside of the front wheel suspension mechanism and the rear wheel suspension mechanism 3S is changed to be hardened relatively to the elastic supporting force on the outside.
