A work vehicle comprising: an actuator (16, 17) configured to pivotally drive an implement; a pivot angle detector (18, 19) for detecting a pivot angle of the implement; a manual controlling section for controlling operation of the actuator (16, 17) based on a manual operation of an operational tool; and an instruction operational tool for instructing execution of a target angle stop control for causing the implement to be automatically stopped at a control target angle (θao, θbo, θco) during continuation of the manual operation; characterized in that the work vehicle further comprises an automatic stop controlling section configured to execute the target angle stop control during continuation of an instruction of execution of the target angle stop control and configured also to cause the actuator (16, 17) to make automatic stop on priority over a control operation by the manual controlling section in case it is detected, during the execution of the target angle stop control, based on an output from the pivot angle detector (18, 19) that a pivot angle of the implement has reached the control target angle (θao, θbo, θco); and in that the automatic stop controlling section is configured also to terminate the target angle stop control thereby to cause the actuator (16, 17) to make the automatic stop immediately, in case one or both of a manual operation on the operational tool and a manual operation on the instruction operational tool is/are released during the execution of the target angle stop control until detection, based on an output from the pivot angle detector (18, 19), of the pivot angle of the implement reaching the control target angle (θao, θbo, θco). an actuator (16, 17) configured to pivotally drive an implement; a pivot angle detector (18, 19) for detecting a pivot angle of the implement; a manual controlling section for controlling operation of the actuator (16, 17) based on a manual operation of an operational tool; and an instruction operational tool for instructing execution of a target angle stop control for causing the implement to be automatically stopped at a control target angle (θao, θbo, θco) during continuation of the manual operation; characterized in that the work vehicle further comprises an automatic stop controlling section configured to execute the target angle stop control during continuation of an instruction of execution of the target angle stop control and configured also to cause the actuator (16, 17) to make automatic stop on priority over a control operation by the manual controlling section in case it is detected, during the execution of the target angle stop control, based on an output from the pivot angle detector (18, 19) that a pivot angle of the implement has reached the control target angle (θao, θbo, θco); and in that the automatic stop controlling section is configured also to terminate the target angle stop control thereby to cause the actuator (16, 17) to make the automatic stop immediately, in case one or both of a manual operation on the operational tool and a manual operation on the instruction operational tool is/are released during the execution of the target angle stop control until detection, based on an output from the pivot angle detector (18, 19), of the pivot angle of the implement reaching the control target angle (θao, θbo, θco).
