PROBLEM TO BE SOLVED: To enable rolling control to be carried out in good responsiveness and high accuracy by using a rolling sensor and an angular velocity sensor even at a turning operation at which a steering wheel is turned over a set value, and to improve the land-leveling degree at the turning operation. SOLUTION: A traveling machine body 1 is constituted so that the turning center of each wheel 7, 12 may be focused on the vicinity of the extension line of a fixed axle 29 at the turning traveling. A turning angular velocityωat the turning traveling is calculated based on a distance W between axles, a distance H between the wheels, a valueθs detected by a turning angle sensor 36, and a value v detected by a speed sensor 35. A disturbance value dθg/dt caused by another axle sensitivity is calculated by multiplying the turning angular velocityωwith the previously set another axle sensitivity of the angular velocity sensor 58 at the turning traveling. The device for controlling the rolling of the implement has an angular velocity-correcting means 67 for correcting the value dθtj/dt detected by the angular velocity sensor 58 at the turning traveling by reducing the disturbance value dθg/dt from the value dθtj/dt detected by the angular sensor 58 at the turning traveling.
