<p>PROBLEM TO BE SOLVED: To provide an agricultural implement capable of simply and rapidly carrying out state changeover of a plurality of preliminary seedling-loading trays, and improving workability of operation for the state changeover of the plurality of preliminary seedling-loading trays.SOLUTION: The agricultural implement includes a support frame 19 formed on the lateral side part of a machine body, and a flexibly swingable link mechanism 60 formed on the support frame 19. At least three preliminary seedling-loading trays 20u, 20m, 20d are connected to the link mechanism 60 so as to extend from the link mechanism 60 to the laterally outside in a cantilever state. The implement is structured so as to be changed over to a superimposed state where the preliminary seedling-loading trays 20u, 20m, 20d are placed in vertically multi-stages in a planar view, and a developed state where the preliminary seedling-loading trays 20u, 20m, 20d are developed into longitudinally and almost in a straight line, by the link mechanism 60. The agricultural implement is provided with a support member 38 stopping the changeover movement of the preliminary seedling-loading trays 20u, 20m, 20d over the developed state by regulating vibration of the link mechanism 60 in the developed state.</p> |
