PROBLEM TO BE SOLVED: To facilitate mounting and dismounting by supporting a transmission by only a center differential case of a front accelerator. SOLUTION: In this riding rice transplanter 10, a rear part of a traveling machine body 16 vertically movably supports a planting part 34, and motive force generated by an engine 20 is inputted to the transmission 22 integrally fixed to the front accelerator 21 through a hydraulic continuously variable transmission (an HST) 58. A nearly central part in the longitudinal direction of the front accelerator 21 is disposed with the center differential case 64 housing a differential gear device 64a, while the center differential case 64 directly supports the transmission 22. The HST 58 and the transmission 22 are disposed before and behind the front accelerator 21 in the machine body advancing direction such that the HST 58 and the transmission 22 sandwich the front accelerator 21, to keep weight balance proper.
