<P>PROBLEM TO BE SOLVED: To solve a problem that in a working vehicle for pulling a ground implement, when a traveling machine is rotated during performance of fixed control of inclination, the ground implement is miscontrolled due to centrifugal force. <P>SOLUTION: The working vehicle 1 includes the ground implement 24 fitted through a link mechanism to the rear part of the traveling machine 2, an inclination control actuator 32 for tilting the ground implement 24 right and left relative to the traveling machine 2, an inclination detection means 81 and an angular velocity detection means 82, which are mounted on the traveling machine 2. The working vehicle is constituted so that drive of the inclination control actuator 32 on the basis of the detection result of both the detection means 81 and 82 performs the fixed control of inclination of the ground implement 24. When the traveling machine 2 is rotated during performance of the fixed control of inclination, the inclination control actuator 32 is driven so that the ground implement 24 has a predefined set angle relative to the traveling machine 2 regardless of the detection results of both the detection means 81 and 82. <P>COPYRIGHT: (C)2012,JPO&INPIT |
