<p><P>PROBLEM TO BE SOLVED: To provide a traveling vehicle such as a riding-type working machine equipped with a turning interlocking control unit, enabling seedlings to be planted at proper positions even if intended for multi-row planting use such as eight-row planting use. <P>SOLUTION: The traveling vehicle comprises a steering mechanisms (175, 180, etc.) capable of changing the directions of front and rear wheels 10 and 11 provided right and left toward the advancing direction through interlocking with the steering direction-determining operation of a handle 34 set on the steering seat of the vehicle 2, and a turning interlocking mechanisms A such as a clutch control arm 86I, a brake control arm 86J, etc. functioning to cut off or brake the driving force of the rear wheel 11 on turning inside through interlocking with the steering mechanisms (175, 180, etc.). In this traveling vehicle, the period of intermittently cutting off or braking the driving force the rear wheel 11 on turning inside by the turning interlocking mechanism A in making a turning of the vehicle, is made shorter, the lower in vehicle speed, while made longer, the higher in vehicle speed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
