<P>PROBLEM TO BE SOLVED: To provide a working vehicle capable of smoothly conducting farm work without causing such situations as the cloggings and/or damage of a ditching machine due to the machine body's backward movement even in case of forgetting the raising operation of a working apparatus such as a seedling planting part or seeder set up liftably. <P>SOLUTION: A seedling transplanter is provided, being such that the working vehicle is mounted with: a link mechanism liftably supporting a working apparatus 4 and its lift position-sensing member; a granule feeder 5 for feeding granules to the ditching machine equipped in the working apparatus 4; a traveling control lever 73 conducting vehicle speed selection in the vehicle's forward/backward movement and the supporting height regulation of the link mechanism and the lever's traveling control-sensing member 73S; a rear wheel rotation-sensing member; an informative member 71; and an information-halting switch 72 laid on the working apparatus 4. In this seeding transplanter, such a control mechanism is constructed that, when all of the three conditions, i.e. the link mechanism is at a defined height or lower, the traveling control lever 73 is at backward movement vehicle speed position, and the rear wheel 11 is under rotation, are met, the informative member 71 is operated until operating the information-halting switch 72. <P>COPYRIGHT: (C)2013,JPO&INPIT |
