PROBLEM TO BE SOLVED: To provide a riding rice planting machine that properly detects the completion of turning at the ridge side.SOLUTION: During the time after a planting clutch is operated in a cut-off state before the turning is started until the turning is started, travel distance detection means detects a travel distance of forward L2 of a machine body and a travel distance of reverse L1 of the machine body, and thereby a difference between the travel distance of the forward L2 of the machine body and the travel distance of the reverse L1 of the machine body is detected. With the completion of the turning, the travel distance of the machine body detected by the travel distance detection means after the turning is completed reaches a predetermined distance with the above difference added thereto so that a seedling planting device 5 reaches a position E1 where the planting clutch is operated in the cut-off state before the start of the turning, and then the planting clutch in the cut-off state is operated to a transmitted state automatically. |
