PROBLEM TO BE SOLVED: To eliminate disadvantages that the planting depth is not stabilized and the maneuvering and operating properties are extremely undesirable due to an undesirable planting operation efficiency because a transplanter for potatoes is provided with a belt conveyor for transferring seed potatoes to a tending machine having two left and right wheels without being subjected to the upper and lower positional control though the transplanter for the potatoes equipped with the belt conveyor for transferring the seed potatoes to the tending machine having the two left and right wheels is cited as a conventional example of this kind. SOLUTION: This transplanter for potatoes, or the like, is obtained by arranging a belt conveyor 34 for transferring seed potatoes, or the like, to the rear of either one rear wheel 2 of the left and right rear wheels 2 in the left and right directions of a machine body and providing a spatial part A for making an operator perform transplanting operations in a lateral part of a maneuvering handle 6 installed at the rear of the machine body and at the rear of the belt conveyor 34 in the transplanter for the potatoes, or the like, capable of supporting the machine body by left and right front wheels 3 and the left and right rear wheels 2, traveling and vertically moving the left and right rear wheels 2 with at least a lifting and lowering actuator 21.
