Tilt the legs of the seedling box rest to the rear, lower the spare seedling box rest to the lower rear, lower the ground height of the spare seedling box rest, and place the spare seedling box on the spare seedling box rest of the seedling planter. It is an object of the present invention to provide a spare seedling box mounting device in a seedling planter, in which a worker can carry out the placement alone from the same position on the ground.

That is, the upper and lower ends of the front leg rod and the rear leg rod on both sides are respectively pivotally connected to the spare seedling box mounting table and the machine body of the seedling plant by the horizontal axis, and the base of the brace is pivoted to the rear leg rod by the rod. A vertically long hole provided with a locking recess above the front end portion is fitted to the stop shaft of the front leg rod, and is loosely fitted to the front end of the brace and provided on the front leg rod so as to be vertically movable. The gold and the operation lever attached to the spare seedling box stand are connected by a wire, and the operating gold is pressed downward by a spring to constitute a spare seedling box stand device in the seedling planter. When placing the spare seedling box on the spare seedling box stand of the seedling planter, the worker can place the spare seedling box on the spare seedling box stand of the seedling planter alone from the same position on the ground. The purpose of doing this is to support the spare seedling box rest on the body of the seedling planter so that it can be moved back and forth by the legs on both sides, A vertically elongated hole with a locking recess at the tip of the brace whose base is pivotally supported by the shaft on the rear leg is fitted to the stop shaft of the front brace, and is loosely fitted to the tip of the brace to move up and down. This was achieved by connecting the gold and the operating lever with a wire and pressing the operating gold downward with a spring.
