<p>PROBLEM TO BE SOLVED: To make an attachment position of a plunger 63 be in almost the same phase and easy to be identified even when the position is changed in a seedling transplanter in which a plunger pump for supplying water to a seedling planting tool is provided, and the plunger of the plunger pump is attached to a crank arm that rotates.SOLUTION: In a seedling transplanter, a plunger pump for supplying water to a seedling planting tool is provided, and a plunger (63) of the plunger pump is attached to a crank arm (60) that rotates. The plunger (63) is selectively attached three positions which are eccentric to the rotation center of the crank arm (60). Among the three positions, one position where a watering amount becomes the highest is arranged in the middle, and remaining two positions are arranged on both sides of the one position.</p> |
