PROBLEM TO BE SOLVED: To provide a seedling transplanting machine for solving problems in which, in the case of the seedling transplanting machine, a planting main transmission shaft for transmission to a seedling planting unit is disposed in addition to an auxiliary speed change switching mechanism of traveling and a differential device, resulting in enlargement of a transmission case, and a transmission member such as a gear is necessary extra to thereby increase the number of parts.SOLUTION: A seedling transplanting machine solves the problem as follows: an auxiliary speed change switching mechanism (71) comprises: an auxiliary speed change switching shaft (72) rotated at the rotational speed after the speed change; a switching member (73) operable in the axial direction; a planting speed transmission member (74) and a road speed transmission member (75) engaged with the switching member (73) in accordance with a traveling state; and one relay shaft (76) for performing transmission of power to the planting speed transmission member (74), etc. Also, a planting main transmission shaft (82) is coaxially disposed on the auxiliary speed change switching shaft (72) in a relatively rotatable manner to each other. |
