SEEDLING TRANSPLANTER

PROBLEM TO BE SOLVED: To solve problems of six-wheel seedling transplanters using only a pair of left and right wheels as driving wheels to cause unsatisfactory driving and propelling power; a problem of a structure which does not vertically move the six wheels in linkage with each other and causes variation of longitudinal inclination of a machine body by vertical motion of the left and right driving wheels; a lack of technological knowledge to lift rearmost wheels operatively connected with turning of the machine body; etc. SOLUTION: The seedling transplanter is provided with left and right driving and traveling apparatuses 2 having left and right front wheels 3 and a plurality of left and right driving rear wheels 2a, and the left and right driving and traveling apparatuses 2 are made to be vertically movable in a state to ground the multiple left and right driving rear wheels 2a. A seedling is transplanted on a field with a seedling transplanting tool 42 of the seedling transplanting apparatus 5 at a position nearly middle of the multiple driving rear wheels 2a of the left and right driving and traveling apparatuses 2 when viewed from a side of the machine body. A steering handle 6 is arranged at a back of the machine body, and the rearmost driving rear wheels 2a of the left and right driving and traveling apparatuses 2 are lifted in a manner linked with the turning operation of the machine body.
