Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring seedlings taken out of a seedling tray with a seedling removal claw when a hard-type seedling tray arranged substantially vertically is fed back and forth. The present invention relates to a seedling transplanting machine including a seedling transplanting unit that is succeeded to a planting nail and is sequentially planted in a field. 2. Description of the Related Art In a multi-row transplanter in which a plurality of seedling transplantation units are arranged on the left and right, each transplantation unit is provided so as to be freely adjustable in the left and right positions, so that it is possible to adjust the interval between the required times. On the other hand, the left and right outermost sides and the rear side of the transplant unit are surrounded by a working step, a protection frame, or the like, to improve workability and protect the unit. [0003] However, since the working steps and the protective frame are usually fixed so that the left and right positions cannot be adjusted, the left and right outermost parts are required when the work between the units is narrow. The distance between the transplanting unit and the working step is increased, so that not only is the workability inferior, but also the lateral width of the entire transplanter is increased. SUMMARY OF THE INVENTION The present invention provides a plurality of seedling transplanting units for taking out seedlings and planting them in a field at the time of laterally moving a hard type seedling tray disposed substantially vertically. In a seedling transplanting machine to be juxtaposed, a gap adjusting means for adjusting the left and right positions of the seedling transplanting unit and a step adjusting means for adjusting the left and right positions of working steps arranged on the left and right outermost sides of the seedling transplanting unit are provided.
