PROBLEM TO BE SOLVED: To provide a transplanter with which supply work is suitably carried out without forgetting the work in the case of shortage of fuel in a fuel tank, shortage of fertilizer in a fertilizer tank, or the like. SOLUTION: This transplanter has an alarm means 8 for informing the shortage of the fuel in the fuel tank of an engine, the shortage of the fertilizer in a fertilizer applicator, or the like, equipped to a traveling machine body and a planting unit for planting seedlings installed to be ascending and descending. An alarm device of the transplanter is constituted by installing the alarm means 8, an alarm-stopping means 12 for stopping the alarm by the alarm means 8 and a transfer movement-detecting means 15 for detecting the transfer movement of the machine body to a succeeding process. When the alarm means 8 gives the alarm, the alarm is temporarily stopped by the alarm-stopping means 12 and, when the fuel,the fertilizer, or the like, is not supplied, the alarm means 8 is operated to alarm again by detecting the succeeding process of the machine body by the transfer movement-detecting means 15.
