PROBLEM TO BE SOLVED: To provide a rice transplanter capable of uniformly correcting the drive of a planting machine and another implement other than the planting machine corresponding to size of the slipping rate of a farm field by a single continuously variable transmission apparatus, wherein the speed change of a planting speed change apparatus does not affect the drive speed of another implement other than the planting machine.SOLUTION: In the rice planter, the continuously variable transmission apparatus is placed in the downstream of a power branch part of travelling power and working power and in the upstream of the planting speed change apparatus, and a power take out part for taking out the power for the another implement other than the planting machine by branching the power before the speed change by the planting speed change apparatus is placed in the downstream of the continuously variable transmission apparatus. The drive power for two or more implements is taken out of a power take out part comprising a single power take out shaft. The transmission shaft positioning at the utmost upstream out of transmission shafts constructing the planting speed change apparatus is brought to be the power take out shaft. The continuously variable transmission apparatus is constituted of a ring cone transmission, and an input shaft, an output shaft and a power take out shaft of the continuously variable transmission apparatus are installed coaxially. |
