PROBLEM TO BE SOLVED: To enable the interval between front wheels and rear wheels to be freely adjusted respectively, and to increase the rigidity of a rear part of a machine frame. SOLUTION: The transplanter is obtained by installing the rear parts of a right and left pair of transmission cases extended in the front and rear direction in both outside end parts of right and left extending sections for link so as to be associated, and installing the rear part of each of the transmission cases in each outside end part of a right and left pair of transmission shaft cases. The rear part of each of the transmission cases is formed into a shape installed in the outside end part of the right or left extending section for the link and the outside end part of the transmission shaft case. Both of the outside parts of the right and left extending sections for the link, and each of the outside parts of the right and left pair of the transmission shaft cases are integrally formed so as to be freely extendable and retractable in the right and left width direction through the right and left pair of the transmission cases to connect the right and left pair of the rear wheels to the front part of each of the transmission cases so as to be associated.
