PROBLEM TO BE SOLVED: To provide a plurality of seeding machines which are connected to attaching members 2 behind the machine frame of a tractor in parallel and are pulled with the tractor to travel, and are easily subjected to a row stop, intrarow adjustment and maintenance. SOLUTION: This seeding machine comprise a seeding machine main body portion 1 and a connection mechanism 3 for connecting the seeding machine main body portion to an attaching member 2. The seeding machine main body portion has driving wheels 7, press wheels 8, seeding devices 9, and power-transmitting mechanisms 11 for transmitting driving forces by the rotation of the driving wheels 7 to the seeding devices in a machine frame 4. The connection mechanism comprises the first arm 29 fixed to the attaching member, the second arm 31 fixed to the machine frame, and a support arm 34 rotatably connected between both the arms. The seeding machine main body portion can vertically be moved and travel while longitudinally vibrating with the pulled travel. The seeding machine main body portion can be locked with a lock mechanism (hook 35 and holding bar 36) disposed in the connection mechanism in a hung posture wherein the press wheel is grounded and the driving wheel is floated from the ground.
