PROBLEM TO BE SOLVED: To easily constitute an interlocking mechanism for releasing a rear wheel side clutch only by handle operation. SOLUTION: This paddy working vehicle comprises a pinion gear 57 mounted on the lower end of the steering rotating shaft 56 of a steering wheel 14 for front wheel steering, and a steering sector gear 53 engagingly driven by the pinion gear 57. It further comprises input aims 50A and 50B for connecting and releasing rear wheel side clutches 45A and 45b, spindle-shaped coil springs 54A and 54B are interlocked with the input arms 50A and 50B, and lateral interlocking rods 53A and 53B are interlocked with the sector gear 52. The free ends of the rods 53A and 53B are inserted into the coil springs 54A and 54B so that the rods 53A and 53B are engagingly locked by the tip minor diameter parts of the coil springs 54A and 54B.
