PROBLEM TO BE SOLVED: To provide a work machine capable of seeding a seed and forming a ridge at a proper position while preparing an appropriate field state for crop growth.SOLUTION: The working machine includes: a pressing wheel 41 which is moved while pulled by a travel part, presses return soil S1 of a ridge furrow T and forms a pressed part S2 along the ridge furrow T made by digging a furrow on a field and re-filling, and is disposed in front of a tilling device 30 tilling outer sides of the ridge furrow T in which the pressed part S2 is formed a seeding device 60 seeding a seed 2 so as to be located in the ridge furrow T in which the pressed part S2 is formed and a ridge forming instrument 50 forming a ridge while covering the seeded seed 2 with soil S3 tilled by the tilling machine 30, the seeding device 60 and the ridge forming instrument 50 being arranged behind the tilling device 30. Pressing, preparation, seeding of the ridge furrow T can be performed simultaneously with ridge forming.
