PROBLEM TO BE SOLVED: To provide a compact mechanism for controlling longitudinal feeding levers in a planting working machine. SOLUTION: The mechanism for controlling longitudinal feeding levers has constitution that two longitudinal feeding levers 44 that regulate the longitudinal feeding amount of seedlings by a longitudinal feeding apparatus 18 and drive the longitudinal feeding apparatus are installed at a fixed distance apart right and left so that the longitudinal feeding apparatus 18 for feeding seedlings on a seedling stand 9 in the longitudinal direction is driven at both right and left stroke ends of the seedling stand 9 on which planting seedlings are placed and which is reciprocatively driven right and left. The right and left longitudinal feeding levers 44 are connected by a connection member 47, an adjustment member 48 for changing the rotation of the longitudinal feeding levers 44 and the connection member 47 are arranged so as to be brought into contact with each other, the rotation starting positions of both the longitudinal feeding levers 44 are adjusted by the contact of the adjustment member 48 with the connection number 48 to regulate the longitudinal feeding amount.
