<p>The present invention addresses the problem of correcting defects such as twisting of transmission elements caused by the operation of nonuniform-speed members in a transplanting machine having a rotary-type seedling planting device. Nonuniform-speed members (48, 56, 121, 122, 98, 99), which transmit nonuniform rotational power to transplanting mechanisms (8), are provided separated into upstream nonuniform-speed members (48, 56, 121, 122), on the inter-row spacing speed-changing device (26) side, and downstream nonuniform-speed members (98, 99), on the seedling planting device side. The upstream nonuniform-speed members (48, 56, 121, 122) are formed so as to be capable of switching between multiple gears, with the acceleration/deceleration ratio changed for each gear, and the downstream nonuniform-speed members (98, 99) are formed in a single gear. In each of the gears for the upstream nonuniform-speed members (48, 56, 121, 122), the setting for the maximum-speed phase, wherein the operating speed of planting claws (96) in the transplanting mechanisms (8) is at the maximum speed, can be changed.</p> |
