<P>PROBLEM TO BE SOLVED: To solve the problems of direct sowing machines comprising the difficulty in the confirmation of proper sowing work owing to the direct driving of seeds into the soil, and practically impossible resowing after improper sowing resulting in the necessity to constantly perform the proper sowing work. <P>SOLUTION: The dibbler is provided with a mobile body traveling by the force of a traveling engine and a sowing device to deliver the seeds by a delivery part driven by a sowing engine and intermittently apply the seed to the soil. The dibbler is provided with a controller to change the driving speed of the sowing engine based on the traveling speed in a manner to apply the seeds at a prescribed spacing independent of the traveling speed of the mobile body. The dibbler is further provided with a delivery period detector to detect the intermittent delivery period by the delivering part of the sowing device and an alarm is generated when the delivery period based on the traveling speed is out of the prescribed value after a prescribed period. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
