It is characterized by that. According to the riding type tea plucking machine of claim 3, the movement reversing link mechanism moves the leaf container from the leaf collecting position to the discharging position, reverses the leaf collecting container at the discharging position, and opens the discharge port. Fresh tea leaves can be stacked downwards on the bed of a carrier. In this way, since the fresh tea leaves can be moved and carried out without the need of manpower, there is no risk of damaging the fresh tea leaves, and the fresh leaves can be easily carried and carried out quickly.

In a tea field, the tea tree grows taller as it grows. Therefore, the height of the cutting blade and the leaf container must be adjusted according to the height of the tea tree.

In the riding type tea plucking machine of claim 3, since the cutting blade and the base of the link mechanism for moving and reversing are attached to the column of the interlocking lifting mechanism, the column is lifted and lowered by the lifting means. Allows the cutting blade and the link mechanism (that is, the leaf collecting container) to be synchronized and moved up and down by the same amount. Therefore, simply adjusting the height of the cutting blade automatically and optimally adjusts the height of the leaf container. Conventionally, the height of the cutting blade and the height of the leaf-collecting container are adjusted separately, which is inconvenient and it is difficult to optimally adjust the height of the leaf-collecting container.
