<p>PROBLEM TO BE SOLVED: To provide a rice planting machine whose body can be turned smoothly by optimally controlling a clutch mechanism for the rear wheel inward of the turn without performing complex operations. SOLUTION: A paddy field working machine has friction type clutch mechanisms for right and left transmission systems transmitting power from non-differential transmission gears to right and left rear wheels and the clutch mechanisms can be controlled by a hydraulic cylinder D. The working machine has a controller 36 which controls a solenoid valve 39 for the hydraulic cylinder D during the operation of steering front wheels, the state of the clutch mechanism is so set on the side that the greater the amount of the steering operation, the more likely it is that the clutch mechanism inward of turn will slip.</p> |
