PROBLEM TO BE SOLVED: To provide a riding type rice transplanter that performs a height adjustment of float rotation fulcrum by an adjustment mechanism arranged separately from a planting depth adjustment mechanism and vertically moves the float rotation fulcrum without changing a position in the longitudinal direction of float machine body. SOLUTION: The riding type rice transplanter includes the rotation fulcrum height adjustment mechanism 28 for lifting, lowering and moving a connection shaft (rotation fulcrum) 36 in the vertical direction relative to a planting depth adjustment link 31 while holding the position of a float 16 (16a) in the longitudinal direction of running machine body on the base of the operation of an operation lever 43. Consequently, the operation of the operation lever 43 reduces the height of the float rotation fulcrum by a planting depth adjustment range or above by a planting depth setting mechanism 58 and the rotation angle in the upward direction of a float tip is enlarged in comparison with a conventional rotation angle and the riding type rice transplanter easily gets across a levee.
