PROBLEM TO BE SOLVED: To provide a sulky working implement travelable in a farming field with a seedling planting device in a stable posture when mud in the farming field is stuck onto a sensor float. SOLUTION: The sulky working implement is such that a farming device( in the Example, the seedling planting device ) is liftably set on the rear side of a traveling vehicle and a ground sensor is provided under the farming device for making a lift control so that the farming device take a desired height above the ground. In this sulky working implement, the lift control sensitivity for the farming device by the ground sensor is regulated based on the result given by a mud-pushing sensor set on the front portion of the ground sensor and detecting the mud-pushing state of the ground sensor.
