PROBLEM TO BE SOLVED: To improve workability in transplanting on a furrow and maintainability of a machine body by improving the composition of a machine body frame and a layout of each part of the machine body. SOLUTION: In a vegetable transplanter 101, a transplantation tine 151 at the lowermost position and rear wheels 117 are arranged to be always overlapped in a side view irrespective of the rise and fall of the machine body frame, and a handle frame 106 is positioned behind the transplantation tine 151. The vegetable transplanter is set up so that from the front side to the back side, the gravity point of the machine body PG, the position of the axis of a rotary shaft PR of a chain case 116, and the positions of the axes PO, P1 of an axle 297 of the rear wheels are positioned in this order. The chain case 116 is rotated to raise the machine body within the range of the rotation to maintain a positional relationship. A fitting structure is configured so that each wheel 112, 117 is positioned at both right and left sides of a front wheel support arm 111 and the chain case 116, and can be respectively changed over.
