<P>PROBLEM TO BE SOLVED: To provide a seedling transplanter having a posture control device for making the travelling posture of a machine body suitable for the work during planting or turning by controlling a rear wheel rolling mechanism with cylinders. <P>SOLUTION: The seedling transplanter includes: a rolling machine frame 41 disposed in the rear of a vehicle body 4 to rotate in the lateral direction around a center rotation axis 42; rear wheel transmission cases 8 and 8 at both ends of the rolling machine frame 41 for feeding rotational drive force to rear wheels 3 and 3; a rotary actuator 9 for rotating the rolling machine frame 41; and a steering angle detection member 7 for detecting the steering angle of a handle 1. The inside of turning is determined from the steering angle detected by the steering angle detection member 7, and the rotary actuator 9 is extended or contracted to rotate the rolling machine frame 41 to a side in which the inside of turning of the vehicle body 4 is low, so that the vehicle body is in an inclined posture. <P>COPYRIGHT: (C)2012,JPO&INPIT |
