86 is pulled out to the left and right as much as possible within the range of the long holes 86c, 86c of the mounting portions 86b, 86b, and is folded upward by turning so as to be in a substantially upright posture. At this time, the springs 86g and 86g are urged to maintain the folded posture. By the way, when the rail guards 86 are folded inward so as to be in a substantially upright posture, the rail guards 86 are foldable (or detachable) seedling mounting portions 42-1. , 42-8 are in a state where they are deployed (or mounted) so that they can be operable, the rail garage is located in the space where the seedling mounting portions 42-1, 42-8 are located.
The doors 86 are located. The folded rail guards 86 are located on the left and right outer sides of the left and right ends 43 'and 43' of the folded support rail, and the left and right ends 43 'and 43' of the support rail. Is located in the folding rotation area of the. Therefore, when the folded (or detached) seedling placing portions 42-1 and 42-8 are operably developed (or mounted), the folded rail guards 86, 86 are preceded therefrom. Must be expanded. In addition, the support rails 43 '/ 4
When the 3 'is operatively deployed, the folded rail guards 86 must be deployed prior to it. Thereby, the folded rail guard 86 is formed.
-You will not forget to deploy 86.

It should be noted that the seedling rest sections 42-1 and 42-
8 is folded inward, and then the support rail
Fold 3 '・ 43' inward, and
When the whole of the riding rice transplanter 1 is viewed in a plan view after the folds 86 are folded inward, the fertilizer applicator 5 provided with the fertilizer tank 5a and the feeding portion 5b in front of the seedling planting machine 4 is provided. Are provided on the inside of the machine body in the left-right direction, and are further provided with spare seedling frames 50
(The seedling frame position is the position of the handle 18 on the left and right sides) is provided on the inside of the body in the left and right direction. In the folded state, the rail guards 86 are located at the left and right outermost ends of the seedling planting work machine 4. That is, the folded rail guards 86 are located on the left and right sides of the left and right outer ends of the left and right side floats 49 and the right and left outer ends of the left and right outer end transplanting devices 41. The support rail is provided so as to be located on the left and right sides from the end and further on the left and right sides of the folded support rail left and right ends 43 'and 43'.
