。DETAILED DESCRIPTION OF THE INVENTION The present invention is provided with a mechanism that automatically and reversibly operates a transmission device interposed in a power transmission mechanism to the traveling device to a lower speed side in conjunction with the raising of the planting device. Regarding a certain rice transplanter.

が要らず、機体操縦を非常に楽に行なえる。In such a rice transplanter, the vehicle speed can be automatically reduced by raising the planting device prior to turning the machine at the edge of the processing area during rice planting work, so the vehicle speed can be reduced without requiring any special operation. The aircraft can be turned safely at low speeds, and the vehicle speed can be automatically raised and returned to the predetermined planting work speed by lowering the planting device after the aircraft has turned, making it easy to adjust the vehicle speed after the aircraft has turned. No special operations are required, making it extremely easy to operate the aircraft.

け装置の上昇量に対する変速装置の変速割合を変更可能
な操作装置を組込んであることを特徴とする。However, the rice transplanter equipped with such an interlocking mechanism has the inconvenience that the vehicle speed decreases even when the planting device is raised while traveling on the road. In view of these circumstances, the present invention has been developed to enable safe turning in the automatic transmission state as described above during planting work, while suppressing an unreasonable drop in efficiency when driving on the road or in a field with good conditions. The purpose is to make things happen. The rice transplanter according to the present invention is characterized in that the interlocking mechanism incorporates an operating device that can change the speed change ratio of the transmission with respect to the amount of rise of the planting device.

つて路上走行速度が低速に制約されてしまう不便を解消
できるに至つた。That is, when driving on the road, the speed change ratio of the transmission device relative to the amount of rise of the planting device is adjusted to a speed change ratio that does not reduce the speed compared to that during planting work.
Even when the planting device is raised, the transmission can be maintained at a relatively high speed, so while the safety effect of turning the aircraft during planting work can be achieved as described above, the road running speed is reduced accordingly. We were able to eliminate the inconvenience of being restricted.
