Claims

[Scope of utility model registration request]

A seedling planting device is attached to a running vehicle body supported by wheels so as to be vertically movable via a lower link and a top link, and the seedling planting device is configured to be vertically raised and lowered by a lifting mechanism in a front vehicle body. In the riding-type rice transplanter, the top link is configured to be movable in the longitudinal direction within an appropriate range, and the top link is configured to be movable in the longitudinal direction within an appropriate range, and the top link is configured to move the top link back and forth within an appropriate range. means for switching the elevating and lowering mechanism between raising and lowering, and the traveling vehicle body is provided with means for pressing and moving the top link in a direction away from the traveling vehicle body when the seedling planting device is significantly raised. Float constant pressure control device for riding rice transplanters.
