Abstract

PURPOSE:To accurately control the operating condition of a differential locking mechanism by controlling to be the stopping condition of differential rotation only when the difference in steering angles between front and rear wheels is small. CONSTITUTION:Steering hydraulic cylinders 8F, 8R for separately changing the directions of front and rear wheels 1F, 1R and their control valves 9F, 9R, a hydraulically operated differential locking mechanism 10 for stopping/ releasing the differential rotation of the differential device 1b of the rear wheels 1R and its control valve 11, and a control device 12 for controlling the control valves 9F, 9R, 11 and a speed change motor 7, are provided in the captioned device. And, a differential locking control means 100 for controlling the stoppage/releasing of the differential rotation of wheels by means of the differential locking mechanism 10 is formed by utilizing the control device 12.
