PROBLEM TO BE SOLVED: To resolve a problem of a conventional hitch unit wherein a work machine is coupled to a work machine attaching beam in the rear of a traveling vehicle via the hitch unit, but the hitch unit is attached to only one center portion of the work machine attaching beam and increased weight of a seeder due to multiple row planting can not be supported by one hitch unit. SOLUTION: A coupling hitch 61 allows the hitch unit 61 attached to a tool bar 21 attached with the work machine to be fixed at one or more optional positions to the work machine attaching beam 2 provided on the traveling vehicle. The coupling hitch 60 is composed of a fitting body 18 to be attached to the work machine attaching beam 2, a fixing screw 6, a body 13 to be fitted for attaching an attaching part 1 of the hitch unit, and a fixing plate 5.
