It is located on the left and right center sides of the seedling mounting table, and the operation and effect are as follows.

[Operation and Effect] Since the operation lever can be covered by the cover member, the operation lever is not unexpectedly operated when the rice transplanters collide with each other or are unconscious. Oil leakage can be prevented.

An object of the ninth invention is to reduce the abrasion of the end surface caused by the contact between the rising wall that partitions the seedling mounting surface for each planting strip and the sliding plate facing the end surface of the rising wall. It is an object of the present invention to provide a rice transplanter seedling mount that can avoid the inconvenience that the entire seedling mount needs to be replaced due to progress.

According to a ninth aspect of the present invention, there is provided a sliding plate for guiding a seedling end surface on a seedling placing surface which moves as the seedling placing table reciprocates left and right, and the seedling placing surface is provided with a planting strip. A detachable spacer is mounted on an end surface of the rising wall which is divided for each side, which faces the sliding plate, and the operation and effect are as follows.

[Effects] The end face of the rising wall which partitions the seedling mounting surface for each planting strip, which is opposed to the sliding plate, is set close to the sliding plate, and comes into contact with the sliding plate. The moving seedling end face is set so as not to be sandwiched between the end face of the rising wall and the sliding plate. Therefore, the end face of the rising wall may come into contact with the sliding plate due to the individual difference of the rice transplanter. Therefore, abnormal wear occurs on the end face of the rising wall, and it is necessary to replace the entire seedling mounting table. . Therefore, a spacer that positively contacts the sliding plate is attached to the end face of the rising wall, and when the spacer is worn, only the spacer is replaced. This eliminates the need to replace the entire seedling mount.
