<P>PROBLEM TO BE SOLVED: To provide a seedling transplanter that reduces a cost and improves maintainability by transmission adjustment of rotation inside of a simple constitution, deals with sudden occurrence of slip, secures planting accuracy and work efficiency and secures output necessary for turning. <P>SOLUTION: The seedling transplanter includes a traveling vehicle body 2 equipped with front and rear wheels 10 and 11 of all-wheel drive, a differential gear apparatus 51 with differential lock mechanism 51a of the front wheels 10, a clutch mechanism 18c of the rear wheels 11, a control rod member 52 for stopping rear wheel transmission of turning inside and a planting apparatus 4 liftably supported by a raising and lowering link mechanism 3 during rotation. The seedling transplanter has a clutch setting mechanism 53 for maintainably setting right and left rear wheel power by action regulation of the right and left clutch mechanisms 18c and 18c and the raising and lowering link mechanism 3 has a rise control mechanism C for lowering the rise position of the planting apparatus 4 with operation of the differential lock mechanism 51a by the slip of the front wheels 10 during machine turning. <P>COPYRIGHT: (C)2013,JPO&INPIT |
