PROBLEM TO BE SOLVED: To provide an inexpensive work vehicle such as a tractor performing rolling control of an implement in good timing. SOLUTION: When the implement 3 connected to a traveling vehicle 1 is a puddling implement 3 for a field performing operation by turning while the implement 3 is kept lowered on the field without lifting the implement 3 during turning of the traveling vehicle 1, centrifugal force acts on the implement 3 because the traveling vehicle 1 turns while traveling on a horizontal plane of the field at a relative high speed during the operation. A slope sensor 10 decides that the machine body is tilted because a viscous liquid in the slope sensor 10 tilts by the centrifugal force thereof. Thereby, a horizontal cylinder 16 is expanded and contracted to shift the implement 3 from the horizon. As a result, the radius of turning is computed by a handle steering angle, and a change in a slope sensor value by the centrifugal force acting on the slope sensor 10 by the radius of turning thereof and car speed as a correction value is added and subtracted from the detected value with the slope sensor. Thereby, the actual tilt of the traveling vehicle 1 can be decided to make the implement 3 horizontal. COPYRIGHT: (C)2010,JPO&INPIT |
