徴とする田植機の変速操作装置。 A rice transplanter comprising an engine at the front of a running body supported by wheels and a seedling planting device at the rear of the machine frame, an output shaft linked to the engine, and an input linked to the wheels and the seedling planting device. Two belts having different transmission ratios are wound around the shaft, and two tension pulleys are disposed in contact with each of the first belt and the second belt, and both tension pulleys A spring is provided for pressing each of the tension pulleys into contact with the belt to bias the power transmission on, and the tension pulleys are moved to a power transmission off position away from the belt by resisting the biasing force of the spring. The two interlocking mechanisms are arranged so that when one tension pulley is in the power transmission on position, the other tension pulley is in the power transmission off position, and one tension pulley is in the power transmission off position. A switching mechanism is provided for switching the other tension pulley to be in a power transmission on position at a certain time, and a clutch lever is further provided to put both tension pulleys in a power transmission off position, A speed change operation device for a rice transplanter, characterized in that the clutch lever is interlocked and connected to a foot pedal provided on the traveling vehicle body so that when the foot pedal is depressed, both the tension pulleys are brought to a power transmission off position. .
